JBL SUB-10 _ POWERED SUB-WOOFER _ SCHEMATIC _ [Circuit Diagram] _ Troubleshooting flow chart
Specifications
Amplifier Power (RMS): 100 Watts
Peak Dynamic Power : 225 Watts
Driver: 10" (254mm)
Inputs: Line Level and LFE
Crossover Frequency: Variable from 50Hz to 150Hz, 24 dB per octave
Frequency Response: 30Hz – 150Hz
Dimensions (H x W x D): 19-3/4" x 14-1/16" x 14-3/4" (502mm x 357mm x 375mm)
Weight: 35 lb/16kg
General Unit Function (UUT = Unit Under Test)
* Switches/knobs on the amplifier face-plate:
* Low Pass Frequency Adjust full CW (150Hz)
* Phase switch – either position
* From the signal generator, Connect both right and left line level inputs (RCA) – not the LFE jack - to signal generator and UUT. Use Y-cable if necessary from mono source.
* On the amplifier, turn the LEVEL control full Counterclockwise (Min).
Turn on generator, adjust to 100mV, 50 Hz.
* Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max).
LED should now be Green; immediate bass response should be heard and felt from rear port tube opening.  Turn off generator, turn LEVEL control fully Counterclockwise (Min), disconnect RCA cable.
Sweep Function
Follow steps above, using a sweep generator as a signal source.
Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofer and test.
Driver Function (Woofer)
* Remove woofer from cabinet; detach + and - wire clips.
* Check DC resistance of woofer; it should be 3.3 ohms ±10%.
* Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
Adjust Level
Turn your Sub-woofer-Level Controlup to the “5” position (halfway). If no sound emanates from the sub-woofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact? 
Is the AC plug connected to a “live” receptacle? 
Has the Power Switch  been pressed to the “On” position? 
Once you have confirmed that the sub-woofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.
Set the overall volume control of the pre-amplifier or stereo to a comfortable level. Adjust the Sub-woofer-Level Control  until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the sub-woofer volume too loud, adhering to the belief that a sub-woofer is there to produce lots of bass. This is not entirely true.  A sub-woofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the sub-woofer so its impact on bass response is always there but never obtrusive.
Phase Control
The Phase Switchdetermines whether the sub-woofer speaker’s piston-like action moves in and out with the main speakers (0˚), or opposite the main speakers (180˚). Proper phase adjustment depends on several variables such as room size, sub-woofer placement and listener position. 
Adjust the phase switch to maximize bass output at the listening position.  Crossover Adjustments  The Crossover Adjustment Control  determines the highest frequency at which the sub-woofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the sub-woofer’s efforts on the ultra deep bass sounds required by today’s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment Control to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE Input ¢ is used. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting.

HOW TO TAKE OUT DISC AT EMERGENCY - harman/kardon - BDP1/BDP10 - Blu-ray Players

December 18, 2014, 6:04 am

TO TAKE OUT DISC
Retrieve a Blu-ray/DVD/CD disc from the tray without power
This method will allow you to retrieve a disc without power in the BDP1/10 or pull out the disc tray if needed.
* Remove all screws holding the top cover on: four screws at the rear and four on the sides. Remove the top cover.
* Tip the unit up to view the bottom of the chassis near the front panel; there are two open slots under the disc mechanism.
(With one free hand, reach inside the unit to support the Blu-ray/DVD/CD disc; it may fall out when you release the loader mechanism in the next step.)
In the slots, you can see a white bar inside. 
* Using a small flat-blade screwdriver, move the slotted bar as far to the right as it will go; this will unlock the loader mechanism and free the disc.
The disc should now be free and can be pulled out the rear of the loader mechanism, if it has not fallen out already. 
Now move the white bar back to the left, to its original location.
NOTE:  There is also a method where you can open the tray without removing the top cover, but in the process of tipping the unit up to slide the mechanism release, the disc may drop out of the tray (and may possibly scratch the disc) and into the unit, so you would still need to remove the top cover.  
In this method, you will need to locate the white locking bar under the unit as described above, without tipping the unit upright. Once this is done, open the hinged tray door with your fingernail. 
Use a pair of long-nosed pliers to reach in and pull the tray out of the loader, exposing the disc.

PN50C450B1DXZA - HOW TO ACTIVATE POWER and LOGIC BOARD TEST PATTERNS WITHOUT MAIN BOARD
HOW TO ACTIVATE POWER and LOGIC BOARD TEST PATTERNS WITHOUT MAIN BOARD
> Remove the power cord to panel.
> Short highest 2 pins # on logic board test jig (can be 4 pin or 6 pin)
> Remove power connector at main board; Keeping connection to SMPS.
> Short “Power On” Pin to circuit ground on Power connector to SMPS.
> Connect Power cord to Panel.
Power Supply Trouble Shooting Notes
  Do not  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)
  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.
SAMPLE VIEW – READINGS & VITAL SIGNS
  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. 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.
