SAMSUNG PN50C450B1 - POWER SUPPLY [SMPS] TROUBLESHOOTING
Firmware: Check Samsung.com for latest update - 3/16/11 IMPORTANT -T-SAT4AUSHC(1008.2 or 1008.3).EXE
You should check serial number and bulletin before updating firmware.
Reason: Red Dot issue. Buzzing noise level will be reduced.
Activating Power & Logic Board test patterns without main board.
* Remove the power cord to panel.
* Short the Highest two pins on the logic board.
* Remove the power connection at the main main board; keeping connection to SMPS. Short the Power ON pin to circuit ground on power connector to SMPS.
* Connect the power cord to panel.
2010/2011 models
Will not be run with the “X” or “Y” main disconnected. The SMPS will shut down immediately. However if a meter is first connected to the test point when power is applied it will read the correct voltage briefly before shutting down.(You have enough time to check key voltages). CAUTION: Do not reconnect any connectors to SMPS or Y/X Boards until power has been turned off long enough for Vs to drop below 10V or damage will occur to X or Y Boards.

CAUTION: Do not reconnect any connectors to SMPS or Y/X Boards until power has been turned off long enough for Vs to drop below 10V or damage will occur to X or Y Boards.
Over Current Protection
For the SMPS Power Supply... If a short circuit occurs on either the VS or VA voltage lines, the SMPS stops operating, but should not fail. When the short circuit is removed from the source line, the Power Supply will operate normally again. Many SMPS Supplies are replaced needlessly.
For the SMPS Power Supply... If a short circuit occurs on either the VS or VA voltage lines, the SMPS stops operating, but should not fail. When the short circuit is removed from the source line, the Power Supply will operate normally again. Many SMPS Supplies are replaced needlessly.
When troubleshooting, It’s very important to first check Vs, Va, Vsc & Ve If Vs is missing (0V), disconnect power and check for short. Use ohm meter to measure resistance while disconnecting Y-Board & X-Board supply feeds one at a time. Turn Power On and Test SMPS with short connector removed for correct Vs voltage verification. (It may only come up briefly but to full level). Again be careful not to reconnect Power Connectors until Vs falls below 10V.
If Va is low or missing, disconnect Supply Feed to Address Boards and Check to see if SMPS Supply is restored. (Note Va feed normally passes through the Y-Drive to the Address Boards (Logic Buffer Boards).
If Vsc is low or missing and Vs was OK, the failure is with the Y-Board since the Y-Board generate the Vsc voltage from the Vs supplied by the SMPS.
If Ve is low or missing and Vs is OK, the failure is with the X-Board since the Ve is generated by the X-Board from the Vs supplied by the SMPS. Please note in some rare cases the Ve may be generated by the Y-Board feed to the XBoard.)
Other SMPS Voltages:
Check Low Voltage feeds to the Main Board and other supplied Assemblies.

WIRING DIAGRAM & SETTINGS
5_4 & 3 CHANNEL SETTINGS
SETTING THE CROSSOVER(S)
Determine your system plans and set the crossover-mode switch accordingly. If your system design does not include a subwoofer, set the crossover mode to FLAT and skip to “Setting Input Sensitivity.”
MODE SWITCH
Flat:Allows a full-range signal through to the speakers; can be used with larger full-range speakers such as 6" x 9"s.
HP:Allows a high-pass signal through to the speakers; should be used with most loudspeakers (can protect your full-range speakers from being overdriven with low frequencies, one cause of speaker damage).
LP:Allows bass to pass through to the speakers; should be selected when powering subwoofers.

HP:Allows a high-pass signal through to the speakers; should be used with most loudspeakers (can protect your full-range speakers from being overdriven with low frequencies, one cause of speaker damage).
LP:Allows bass to pass through to the speakers; should be selected when powering subwoofers.
Initially set the crossover-frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible. Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. Adjust the crossover frequency to limit bass, and provide increased system volume with less distortion.
For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer. The subwoofer output of the 5760a/5761a is low-pass only and does not have a crossover-mode switch.
SETTING INPUT SENSITIVITY
1 Initially turn the INPUT LEVEL control(s) to minimum (counterclockwise).
2 Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track.
3 On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard. [After the source unit is on, blue LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit.]

REMOTE LEVEL CONTROL (OPTIONAL)
All three Reference subwoofer amplifiers and the 5760a/5761a amplifier have inputs for an optional remote level control (100rc). This will allow the subwoofer level to be adjusted from the listening position. Connect the optional remote level control using the RJ-11 jack on the side of the amplifier. Install the control module in the front of the vehicle within easy reach of the driver. Both the underside of the dash and the center console are suitable locations. Refer to the mounting instructions accompanying the 100rc.

The Blinking LED Procedure
The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly. Errors can also be displayed by the blinking LED procedure. The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
> 1 long blink of 5 seconds to start the sequence.
> 12 short blinks followed by a pause of 1.5 seconds.
> 9 short blinks followed by a pause of 1.5 seconds.
> 6 short blinks followed by a pause of 1.5 seconds.
> 1 long blink of 1.5 seconds to finish the sequence.
* The sequence starts again with 12 short blinks.

NVM Editor
In some cases, it can be convenient if one directly can change the NVM contents. This can be done with the “NVM Editor” in SAM mode. With this option, single bytes can be changed.
Do not change these, without understanding the function of each setting, because incorrect NVM settings may seriously hamper the correct functioning of the TV set.
Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect.
Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect.
Load Default NVM Values
It is possible to upload the default values to the NVM with ComPair in case the SW is changed, the NVM is replaced with a new (empty) one, or when the NVM content is corrupted. After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed.
Unstable Picture via HDMI input
Check (via ComPair or factory mode) if HDMI EDID data is properly programmed.
No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
TV Do Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
Audio Amplifier
The Class D-IC U606 has a power pad for cooling. When the IC is replaced it must be ensured that the power pad is very well pushed to the PWB while the solder is still liquid. This is needed to insure that the cooling is guaranteed, otherwise the Class D-IC could break down in short time.
CSM [Customer Service Mode]
When CSM is activated and there is a USB memory stick connected to the TV, the software will dump the complete CSM content to the USB memory stick. The file (Csm.txt) will be saved in the root of the USB memory stick.
Loudspeakers
Make sure that the volume is set to minimum during disconnecting the speakers in the ON-state of the TV. The audio amplifier can be damaged by disconnecting the speakers during ON-state of the set.
Display option code
Attention: In case the SSB is replaced, always check the Panel Code in CSM, even when picture is available. Performance with the incorrect display option code can lead to unwanted side-effects for certain conditions.
SSB [Small Sognal Board] Identification
SSB’s of this chassis are identified by a “715” code on the SSB. 715Axxxx-Nnn-MMM-OOOO
> 15 main category, Printed Wiring Board
> Axxxx sub category, sequential coding number
> Nnn Version code
> N Development number
> nn Production number
> MMM Mounting variation code
> OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement panel.

> OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement panel.
Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB.
A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Dealer options” items in SAM (do not forget to “store”).

After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. The loading of the CTN and production code can also be done via compare (Model number programming). In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
Remark:
# After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address>
# Select the item and press <OK> on the RC.
