Schematy są ale można wysilić się i zrobić kolorowy skan i o większej rozdzielczości. Wtedy schematy płytek będą czytelniejsze. Całość super jako wartość merytoryczna. Wszystkie dane potrzebne do podłączenia różnego rodzajów urządzeń takich gramofon, CD itd.

Szybko, sprawnie i tanio. Serwis godny polecenia. Będę polecał innym

Ogólnie jest OK, z wyjątkiem obrazu płyty głównej, który jest miejscami mało czytelny, ale można sobie poradzić.
;
Dokładna dokumentacja, pomogła w szybkiej naprawie telewizora. Dziękuję!

jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.

4 Diagnostic mode
This mode is only for servicing and checking the circuit design, and not open to users. When the STEREO/DIRECT key and TONE + key are both held pressed for 2 seconds in Standby mode, the power is turned on, and the number of times of each defect or Speaker relay off by abnormality detection is sequentially displayed on the FL display. Displayed items: � DC detection � Overload detection � Fan detection � Temperature detection Hold the STEREO/DIRECT key and TONE + key pressed for 2 seconds in Standby mode.

Protection Process List
Item Purpose Detection Method Process Turns muting on and speaker relay off, then turns off the power after 3 seconds. Warning Indication Remarks To detect amplifier damage (defect status) A process to DC protect speakers detection (for protection of connected external devices) To detect overloading (abnormal status) With lowload driving or a short circuit of the speaker terminals (for protection of the amplifier) Flashing "AMP ERR" for Once detected and turned 3 seconds. the power off, input a key Flash the standby LED never again. after the power off.
Detects when the DC_DET port becomes "L".
D
Turns muting on and Detects when the AMP_OL port speaker relay off, and becomes "L" (checks by interrupt). immediately turns off the power. Detect temperature more than 100°C. Turns muting on and speaker relay off. Rotate the fan None
AMP overload
Continue flasing with "OVERHEAT" Mute, relay and warning indications is leading hold.
Fan control
Protection function against a temperature rise at the heat sink
Detect temperature of 90 to 100°C. Rotate the fan Detect temperature of 74 to 90°C. Detect temperature of 69 to 74°C. A condition except the above. Rotate the fan Fan is leading hold Stop the fan Turns muting on and speaker relay off, then Flashing "FAN STOP" turns off the power after 3 for 3 seconds seconds. Turns 12V_TRG port to "L", then turns off the 12V output.
Mute off & relay on (normal mode)
E
Fan stop
To know that the rotating fan is forcibly stopped
Detects when the FAN_DET port becomes "L".
If the FAN_DET port becomes "H" within 3 seconds, the unit resets automatically. After the power off, the key input is possible once again. Only a fan that is assigned 12V TRIG is valid.Release the FL indication with the power on/off.
Detects when the 12V_DET port 12V trigger To detect the shortcircuit of 12V trigger circuit becomes "H".
