4. If the problem still exists, go to HDMI EDID Ver menu, and change the HDMI version to HDMI 1.2 or HDMI 1.3.
5. Change the Main Board if same problem occurs.
HOW TO SET-UP NETWORK
Click the [Menu] button and open [Setup] to select [Network].  Confiure wired or wireless network settings.
How to check the network status
Select [Menu] >[Setup] >  [Network] and run [Network Test] to see test results and check the network status.
In a network test over a wired connection, the second items which include the IP address, subnet, gateway and DNS server fail.
If the IP address, subnet mask and gateway address were typed in manually, check that valid values were entered.  (For example, 0.0.0.0 is not valid for an IP address, subnet mask or gateway address.)
If the IP address the user entered in is invalid, change it to a valid IP address.
In a network test over a wired connection, the third item, gateway ping fails.
1. Check that the network cable is connected to the TV correctly.
2. If the TV is connected correctly, check whether the IP address is automatic or manual.
3. If the IP is automatic and connected to a sharing device, check the settings of the sharing device (AP) that is using a cable connection, or consult the corresponding Internet service provider.
4. If the IP is manual, check if the IP address is entered correctly. (Here, the user should confirm if the manual IP address entered in is valid.)
Cannot connect to a wireless network.
1. If an encryption key must be entered in to connect to a sharing device, please check that the correct password set for the sharing device is entered.
2. Search surrounding sharing devices to see if there is a sharing device with the same SSID by selecting [Wireless Network Setup] and [Select Network].  If there is a sharing device with the same SSID, try to connect to this device.
3. If the IP address is set to automatic and you cannot connect to the sharing device using option 1 or 2, check the settings of the sharing device to see if the DHCP server function on the sharing device is enabled. If disabled, activate the function. (For details on how to set up the sharing device, see the manual for the corresponding sharing device.)
4. If you still cannot connect to the sharing device after confirming options 1, 2 and 3, reset the sharing device and try again.
When using a wireless network, the user’s wireless sharing device cannot connect to the PBC (WPS)
Check if the sharing device of the user supports WPS.
2. Check if the user pressed the PBC button on the sharing device.
3. If there is another sharing device with WPS running nearby, a connection cannot be made. Please retry after 2 minutes.
4. Reset the sharing device and retry.
5. If the sharing device of the user is not Wi-Fi certified, it may not be able to connect using WPS.
The auto-configuring sharing device cannot be connected to automatically through a wireless dongle.  (Here, the user’s sharing device must support auto-configuration.)
1. Check if the sharing device of the user supports auto configuration.
2. If the sharing device of the user supports auto configuration, place the sharing device as close as possible to the wireless dongle on the TV and try to re-establish the connection. (Must be placed close to the TV to establish a connection.)
Cannot connect to a wireless network (2) or AP
* There could be several causes of the connection failure. Check the AP settings to see if the following condition is found.
* The Pure high-Throughput 802.11n mode (or Greenfield 802.11n mode) is selected and the Encryption type is set to WEP, TKIP or TKIP-AES. • Under the conditions stated above, Samsung TVs will not support a connection in compliance with new Wi-Fi certification specifications. This is intended to maximize the performance of the AP, TV and TV network.  To connect to the AP, set the Encryption type to AES. If Pure High-Throughput 802.11n mode (or Greenfield 802.11n mode) is selected and the Encryption type is set to AES, your Samsung TV will connect to the AP providing you with optimum
performance.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration.
Select [Menu] > [Setup] > [Network] and check if SWL is Off.
If the AP is turned off, the TV will try to re-establish a connection for 2 minutes.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration and a message that it is connecting is displayed only
Check if the AP is not turned off during connection.  If the AP is turned off, the TV will try to re-establish a connection for 2 minutes.
In order to use the Samsung Auto Configuration function, I did as the user manual instructed. I get a message that connecting to an external network has failed
The Samsung Auto Configuration feature is designed to establish an auto connection between the TV and the gateway of the AP. It performs a connection test if the AP is connected to an external network.
If the AP is not connected to an external network, a message that establishing a connection to an external network has failed is displayed. In this case, connect the AP to an external network. After a connection to the external network is established through a network test, you can use the network without any problem. Check if the AP is connected to an external network.  If you perform a test when a connection to an external network is established through a LAN cable, you will obtain successful test results.
When SWL is On,  cannot connect to the 5GHz Wi-Fi mobile device
SWL is connected to a Wi-Fi mobile device which uses 2.4GHz bandwidth and supports PBC (Push Button Configuration) mode.  A mobile device which uses 5GHz or 2.4GHz bandwidth but does not support PBC cannot be connected to the TV.
* WPS: WPS is the acronym for Wi-Fi Protected Setup, and includes two types: PBC (Push Button Configuration) type which performs cross certification with the press of a button and PIN type which performs cross certification when a PIN (Personal Identification Number) code is entered.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration and a message that it is connecting is displayed only.
* If Samsung Wireless Link is On, a 5G-bandwidth wireless sharing device may not be found in a search (restriction).
* If Samsung Wireless Link is Off or the product does not have the Samsung Wireless Link function, please retry searching to fid the sharing device. (May not be found in a search depending on the settings of the wireless connection.)
In a network test over a wireless connection, the second items which include the IP address, subnet, gateway and DNS server fail
*If the IP address, subnet mask and gateway were typed in manually, check that valid values were entered. (For example, 0.0.0.0 is not valid for an IP address, subnet mask or gateway address.)
* If the IP address the user entered in is invalid, change it to a valid IP address.
In a network test over a wireless connection, the third item, gateway ping fails.
1. If the IP address is automatic and connected to a sharing device, check the settings of the sharing device (AP) that is using a cable connection, or consult the corresponding Internet service provider.
2. If the IP address is manual, check that the IP address is entered in correctly. (Here, the user should confirm if the manual IP entered in is valid.)
In a network test over a wireless connection, the fourth item, Internet service test fails.
Consult the corresponding Internet service provider (an Internet network service provider the user has subscribed to such as KT)

SELF DIAGNOSIS
  The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to fl ash. The number of times the LED fl ashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
  When an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas.  Results for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, an error has occurred.
* If a +B over-current is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the micro-controller is displayed on the screen.
** Check the screen (G2) voltage for abnormality in this case.
*** If STANDBY/STEREO LED flashes six (6) times, unplug the unit and wait 10 seconds before performing the adjustment.

Clik here to view.
Stopping the Standby/Timer LED Flash
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER LAMP from flashing.
Self-Diagnostic Screen Display
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to bring up past occurrences of failure on the screen for confirmation. 
To Bring Up Screen Test
In standby mode, press buttons on the Remote Commander sequentially, in rapid succession.
DISPLAY> Channel [5]>  Sound volume (--)> Power ON.
Handling of Self-Diagnostic Screen Display
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to “0”.  Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after completion of the repairs.
Clearing the Result Display
To clear the result display to “0”, press buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as shown below:
Channel 8> ENTER
Quitting the Self-Diagnostic Screen
To quit the entire self-diagnostic screen, turn off the power switch on the Remote Commander or the main unit.
Self-Diagnostic Circuit
+B over-current (OCP)
Occurs when excessive current fl ows through R5013. The increase in voltage across R5013 causes the output of Q5004 to go high, and this high signal goes to the micro.
+B over-voltage (OVP)
IC6505 detects +B OVP condition and turns on Q6522. This sends a high signal to the micro and also shuts down the AC relay.
V-STOP
Occurs when an absence of the vertical de fl ection pulse is detected by pin 24 of IC2801 (B Board). Power supply will shut down when waveform interval exceeds 2 seconds.
White Balance Failure
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC2801. TV will stay on, but there will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
1. Occurs when set 5V is out.
2. Horizontal Deflection Stopped
3. Occurs when either:
1) a +B over current is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).

THE TV IS HOT
Since a PDP TV displays a picture on the screen by discharging plasma, operating for a long time may introduce heat onto the panel. The internal heat of the panel is sent to the vent on the upper part of the product, and users must take care not to touch the hot air from the vent.  The heat from the PDP TV does not indicate a defect or problem.
NOISE FROM THE TV
A PDP TV may produce sound at a certain level when operating the fan to cool its internal temperature. In addition, since the high-speed switching circuit and the high current may produce noise depending on the screen brightness change, a PDP TV produces more noise than a conventional CRT TV.
AFTER IMAGE REMAINS ON SCREEN
Due to the nature of PDP TVs, partial after-images may appear if a still picture is displayed for a certain period of time after connecting a video game console or a computer.  This is caused by brightness deterioration due to the storage effect of the panel, and to prevent this from happening, we recommend you reduce 'brightness' and 'contrast'.
RED OR BLACK SPOTS APPEARS ON THE SCREEN
A PDP TV uses a PDP panel consisting of 123million (SD Grade) ~ 315million (HD Grade) pixels. Although a PDP panel is a product that requires high technologies to integrate a few million pixels, a bright or dark pixel may exist on the panel, this does not affect the performance of the product.
BOUNDARY APPEARS ON THE SCREEN
Displaying a still picture on the screen may permanently damage the PDP panel.
A boundary may appear due to the difference in the transparency of the panel when watching the picture in the 4:3 aspect ratios for a long time and the picture in the left, right and center screens is a still image.
A boundary may appear when watching a still picture from a DVD player or a video game console on the screen for a long time.
UNUSUAL LINES APPEARS
Keep the antenna away from the power cord or connectors if possible.
The SMPS relay repeatedly turns on and off by the protection function due to a defect on a board connected to the SMPS.
> Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if each voltage output is correct.
> If the symptom continues even when SMPS is operated alone, replace the SMPS.
> If the symptom is not observed when operating the SMPS alone, find any defective ASSYs by connecting the cables one by one.
[When separating and connecting the cables such as CN809 of the Main SMPS, CN1, CN2, CN3, CN4 and CN5 of DC-DC SMPS, CN of the X Drive Board, and CN of the Y Drive Board, a spark may be generated by the electric charge of the high capacity capacitor. Therefore, wait some time after separating the power cord from the unit.]
The SMPS relay or the LEDs on the front panel do not work when connecting the power cord if the cables are improperly connected or the Video Board or SMPS is out of order. In this case, check the following
* Check the internal cable connection status inside the unit.
* Check the fuses of each part.
* Check the output voltage of SMPS.
* Replace the Video Board

SAMSUNG PS42D5SX/XEC_PS42D5SX/XSG_PS42D5SX/XTL _ SMPS [Power supply regulator board] – VOLTAGES – PROTECTIONS
SAMSUNG 42"& 50" PLASMA TV - SMPS OUTLINE
   Considering various related conditions, the switching regulator with good efficiency and allowing for its small size and light weight was used as the power supply for PDP 42" (Schubert) / 50" (Strauss), VS requiring high power consumption Asymmetrical Half Bridge converter and fly back converter. To comply with the international harmonics standards and improve the power factor, active PFC (Power Factor Correction) was used to rectify AC input into +400V DC output, which in turns used as input to the switching regulator.
An output short circuit is defined as output impedance of less than 300Mohms.    The power supply shall shutdown and latch off for shorting VS DC rails to return. Shorts between main output rails and STD_5V shall not cause any damages to the power supply.  The power supply shall either shutdown and latch off for shorting is removed, the P/S shall recover. The power supply shall be capable of withstanding a continuous short-circuit to the output without damage or over stress to the unit (components, PCB traces, connectors, etc.) under the input conditions specified in Section 3 above. Current Protection as defined below.
   The over voltage sense circuitry and reference shall reside in package that are separate and distinct from the regulator control circuitry and reference. No single point fault shall be able to cause a sustained over voltage condition on any of all outputs. The supply shall provide latch-mode Over Voltage Protection as defined below.
INPUT
   The power supply shall be capable of supplying full rated output power over free voltage ranges that are rated 100 VAC - 240 VAC RMS nominal. Operating voltage : 90 VAC - 264 VAC The power supply must be able to start up under peak loading at 90VAC. The power supply shall automatically recover from AC power loss. (Note that nominal voltages for test purposes are considered to be with +/- 1.0V of nominal).  STD_5V & Vpr2 (3.3V) is a SELV standby voltage that is always present when AC mains voltage present.
[Normally there is no repair to these SMPS boards, except for damaged or bulged main filter capacitor replacement.  It is advised to replace it as card basis.  After SMPS board replacement, Va & Vs voltages to display panel should be adjusted as per indication at the silk-screen at the panel.  These voltages will differ to panel to panel.]

SET DEAD.  NO POWER
  When switch ON, there is no power light or any other indication.  Sometimes, the Power LED may light up, and shut down atonce.
The power supply section circuit to this kit has short circuit protection.  By anyway, any short circuit occurs at the main board, the power won’t switch ON.  The main cause found to this circuit is with shorted Horizontal Output Transistor [2SD1651C / 2SD2499; (Collector to Emitter or Collector to Base; short).  The best way to troubleshoot is, just de-solder out the horizontal output transistor from the PWB, and just switch ON the set, and see whether the Standby Light is ON.  If it does, make sure that this transistor is damaged.
Before replacing this transistor, just check for any other reason for its failure.  The C435 & C438 should be checked with a capacitance meter for its capacity.  It will be best to replace both of them at the same time, along with the horizontal output transistor.  Even loose solder terminals at these capacitor terminals will surely make the H-Out transistor get shorted.  Check VD435 & VD436 and C437 too.  Without checking all these components and its soldering thoroughly, never switch on the set with a new H-Out transistor.
  The next possibility for H-out transistor failure is; it’s loose seating screw with the heat sink.  Another one is with shorted winding [Horizontal section] of the deflection yoke.  Other is HOT [Horizontal Output Transistor; otherwise called as LOT BSC24-01N4014K / BSC25-09N20E.  Check all the solder terminals to the leads of this Line out Transformer [LOT] too, for any loose soldering.
  If deflection yoke winding has any short (this short can’t be measure by normal technique or with a multimenter); it should be replaced before switch on the set.  You can switch ON the set without this deflection yoke connection; but; must unplug the CRT base card from the CRT base; otherwise there is a chance to make a dark spot at the center of the screen due to accelerated beam of electrons inside the CRT, without any scanning.  It will fall straight at the center of the screen itself, provided the LOT and H-Out transistor as well as the SMPS is OK.  Be sure about this, when you switch on the set without deflection yoke connection.  This is true to any CRT based televisions; irrespective of its brand and size.
  If the horizontal output transistor is found damaged, check the load resistor R551 2.2Ohms 2W W/W for open.  In most cases, this won’t happen to this kind of circuit, as any short circuit occurs at the secondary stage of the SMPS will clause the SMPS to shut down instantaneously.
  In practice, this is the most venerable fault that can occur to sets fitted with this kit.  90% of it I did faced was it. 
  If the LOT is defective (Internal short in its winding), the horizontal output transistor will heat up within seconds.  To make this sure, just switch ON the set, and see whether the standby light lights up.  If it does, just switch it OFF after 30 or 40 seconds, and unplug the set from AC mains wall socket, and feel the heat of the horizontal output transistor with bare fingers.  It can be slightly warm, but not too hot.  This effect can due to a damaged deflection yoke too.
 It is advised to re-solder all the terminals of IC LA76810 / LA76818A; because this IC will heat up to an extent while the set works, and repeated heating and cooling can make its solder terminals to expand and shrink; and make any loose solder terminals, so microscopic to see with naked eye.  It is be best to suck out the solder from each terminal; using a solder suction pump and re-solder it by applying fresh solder, without making any solder bridge short in between.  Be very careful.  After soldering the IC terminals, clean it using Medical Quality Turpentine or Rectified Spirit. 
  In most cases, the main system control IC found OK.  Do not do any unwanted checks and meter prods touches to it; when power is ON.  This is a very sensitive IC; can be damaged easily.
  The SMPS circuit to this set is quite simple related to STR based ones, and is easy to follow.  I’ve here described some service experiences of mine with this type of kit.  There might be more to describe for others.  Service experiences to person to person will be different indeed.
