REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

Press and hold STANDBY/ON on the Player until "RESET" appears on the front panel display when the Player does not operate properly even after the power has been turned off. Then turn on the power again.
# It may take several minutes until completion as the system check will be executed when the power is turned ON. Please wait until the indicator lights up in this case.
# Since all settings including the language setting stored in memory are also reset when a reset has been performed, they must be set again.

TROUBLE SHOOTING
Power does not come ON.
Is the 12V power supplied to pins (2, 3 and 4) of P9001 inside MAIN PWB-S (AT_12V) while AC is ON and the power source is OFF >>The POWER Assy is normal. (12V power is supplied.) Replace and check MAIN PWB-S.
Disconnect the P9001 connector on the MAIN PWB-S after turn the power off, then do not pins 2 and 5 of P9001 on the MAIN PWB-S short-circuit >>Replace and check the MAIN PWB-S. (Short-circuit is being caused in the MAIN PWB-S.).
Is the 12V power supplied to pins (2, 3 and 4) of CN901 on the POWER Assy (AT_12V) while AC is ON and the power source is OFF >>Replace and check the POWER Assy. (The circuit up to 12 V generation in the POWER Assy has broken down.).
Check between CN901 on the POWER Assy and P9001 on the MAIN PWB-S and their peripheral circuits. (e.g. nearly detached connector, disconnection).
BD drive does not operate properly.
Does the problem (discs cannot be played back stably) happen only to certain discs >>
(In case discs cause the problem)
1 Check any dirt on discs.
2 Check whether the problem is disc-specific.
Does the problem happen only to BD, DVD or CD >>(In case LD breakdown etc. causes the problem) Replace and check BD drive.
Is the error rate wrong >>
(In case the problem derives from PU breakdown or disc-related factors)
1 Check any dirt on discs
2 Check whether the problem is disc-specific (e.g. Pirated edition)
3 Replace and check BD drive
1 Check the drive relay board (BRIDGE Assy) and circuits around CN101 and CN104. Check any connector nearly detached or obliquely inserted. Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
Discs cannot be played back stably.
Does SLED motor initialize while the power is ON >>
1 Check the drive relay board (BRIDGE Assy) and circuits around CN101 and CN104.
Check any connector nearly detached or obliquely inserted.
Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
Does it load >>
1 Check the drive relay board (BRIDGE Assy) and circuits around CN102 and CN104.

How to open the tray when the power cannot be turned on
When the tray cannot be opened because the power cannot be turned on, it can be opened using the emergency disc ejection rod (GGF1529). (A long, thin rod about 1 mm in diameter can be used in place of the rod.) Bend the emergency disc ejection rod at aright angle, and insert it horizontally into a hole as shown in the figure.
