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.

BASE UNIT TEST MODE
Automatic Answering System Test Mode [Start-up] While pressing the �MEMO�, �ANSWER� and BOX3� keys all at the same time, turn on the .main power or reset the system. Then the beep tone sounds for 500 ms and the test mode starts up. Initial setting of the DSP is established and the flash memory data is checked during start-up. If the first status is not returned from the DSP during initial setting of the DSP, the initial setting of the DSP and the flash memory data test are not performed and the system enters the test mode idle state. [Test Mode Idle State] When the machine is in the test mode idle state, the LCD �0� indicator lights and the ASNWER LED, IN-USE LED and NEW CALL LED are turned off. During the test mode idle state, the DSP is in the DSP idle state (i.e., microphone, speaker and intercom are in the MUTE state), the machine is in the normal charging mode, the communication line is in the open state and the volume setting is in the initial state. However, the audio path setting is valid. The desired test mode can be selected form the test mode idle state by pressing the VOLUME +/- keys as the test modes are numerically displayed on the LCD. Press the �ANSWER� key and the system enters the test mode. Press the �ERASE� key to return from the test mode to the test mode idle state. 1. Key Input and LED Test; LCD �0� indication Select the test mode �0� from the test mode idle state using the VOLUME +/- keys. Press the �ANSWER� key and the system enters the test mode �0� [Key Input and LED test mode] . Press the keys in the following order. The LEDs light up accordingly. �MEMO� n �ERASE� n �ANSWER�(ANSWER LED lights up)
n �GREETING PLAY� n �GREETING REC�n �TIME�n ��� n �+�(NEW CALL LED lights up) n �BOX3�n �REPEAT�n
3. LCD Test; LCD �2� indication Select the test mode �2� from the test mode idle state using the VOLUME +/- keys. Press the �ANSWER� key and the system enters the test mode �2� [LCD test mode]. � During the �LCD test� mode, the following indication patterns are displayed alternately every 0.5 second interval by the LCD segments. Indication pattern 1
Indication pattern 2
� The system returns to the test mode idle state when the �ERASE� key is pressed during the LCD test mode. 4. DSP Signal Detection Test; LCD �3� indication Select the test mode �3� from the test mode idle state using the VOLUME +/- keys. Press the �ANSWER� key and the system enters the test mode �3� [DSP Signal Detection Test mode] . During the �DSP Signal Detection Test� mode, detection of the FSK, CAS, DTMF, VOX and Call Progress Tone signals is performed. � The LCD indications of BOX1, BOX2 and BOX 3 are turned off. The LCD indications of MESSAGE COUNTER shows �- -�, and that of MAILBOX flashes. � The communication line is closed, the DSP enter the following state: The send state is established, the MIC MUTE state is established, the call reception is set to ready, the speaker is turned on and the system waits for receiving the signal. � While the DTMF is being detected, the DTMF number is indicated on the MESSAGE COUNTER of the LCD. When asterisk (*) is detected, the indication �A� appears. When sharp �#� is detected, the indication �C� appears. When the DTMF is not detected, the indication �- -� remains appear. � While the VOX is being detected, the LCD indication of BOX1 appears. When the VOX is not detected, the LCD remains turned off. � While the Call Progress Tone (BUSY TONE, DIAL TONE) is being detected, the LCD indication of BOX2 appears. When the Call Progress Tone is not detected, the LCD remains turned off. � When the CAS is detected, the LCD indication of BOX3 appears. After the CAS is normally detected once, the LCD remains turned on. � The system returns to the test mode idle state when the �ERASE� key is pressed during the DSP Signal Detection Test mode.
�BOX2� n �SKIP� n �BOX1� n �HANDSET LOCATOR�(INUSE LED lights up) � Whenever the respective keys are pressed, the key touch tone sounds. If the keys are press in the wrong order, the error tone sounds and the system returns to the test mode idle state. When all keys are pressed in the correct order, the ringer of completion sounds and the system returns to the test mode idle state. � When the keys up to �ANSWER� are pressed, the ANSWER LED lights up. When the keys up to �+� are pressed, the NEW CALL LED lights up. When the keys up to �HANDSET LOCATOR� are pressed, the IN-USE LED lights up. 2. Call Arrival Detection Test (Related to ASIC); LCD �1� indication Select the test mode �1� from the test mode idle state using the VOLUME +/- keys. Press the �ANSWER� key and the system enters the test mode �1� [Call Arrival Detection Test mode]. � During the �Call Arrival Detection Test� mode, the communication line is in the open state, the machine monitors the RING DET (IC201, 25-pin: port 30). When the RING DET port is �LOW� (the arrival call is present), the ANSWER LED lights up. When the RING DET port is �HIGH� (the arrival call is absent), the ANSWER LED turns off. � The system returns to the test mode idle state when the �ERASE� key is pressed during the Call Arrival Detection Test mode.
