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.
3-1. MECHANICAL ADJUSTMENTS
When replacing any drum related parts, after S2, T2 and F guide adjustments have been made, tape pass fine adjustment (�1.5FWD mode) in Electrical adjustment should be performed. S2, T2 and F Guide Adjustments Adjustment Method: 1. Enter the Test Mode 1 (see page 19.) and set the test tape TY7252 (8-909-822-00). 2. Set the REC MODE switch to STANDARD 48k and press the AMS + key. While in FWD mode, check that there is no curl on the upper and lower flanges of the S2, T2 and F guides. If any curl is present, put the S2, T2 and F guide of concern back in the high position and adjust by adjusting the direction of tightening.
* What is curl?
FWD Back Tension Adjustment Adjustment Method: 1. Enter the Test Mode 2 (Torque Measurement Mode) (see page 19.) and set the torque meter TW-7131 (8-909-708-71). 2. Press the PLAY (�) key. 3. Press the AMS + key or = key and adjust so that the back tension (S side) is within the range of 8.5 ± 0.5 g�cm. 4. When the torque meter is circulating around, check the indicated value. 5. Verify that the maximum value is less than 19.5 g�cm. REV Torque Check and REV Back Tension Check Check Method: 1. After FWD torque adjustment and FWD back tension adjustment are completed, press the PLAY (�) key again and set REV (�) mode. 2. Check that the REV torque value is within the range of 13.5 to 17.5 g�cm and that the REV back tension value is within the range of 7.5 to 11.5 g�cm. Tape Pass Fine Adjustment (�1.5FWD Mode) When replacing any drum related parts, be sure to perform this adjustment. Adjustment Method: 1. Connect the CH-1 terminal of an oscilloscope to TP (RF) and the CH-2 terminal to TP (SWP) on the DIGITAL board. 2. Enter the Test Mode 1 (see page 19.) and set the test tape TY7252 (8-909-822-00). 3. Press the AMS (+) key. Role of each switch in test mode.

3-2. ELECTRICAL ADJUSTMENTS
End Sensor Adjustment When removing the holder assy and when replacing the mechanism deck block, this adjustment should be performed. Adjustment Method: 1. Connect the CH-1 terminal of an oscilloscope to TP (S-END) and the CH-2 terminal to TP (T-END) on the DIGITAL board. 2. Enter the Test Mode 1 (see page 19.) and set the end sensor cassette tape (see page 19.) 3. Set the STOP (p) mode. 4. Adjust RV502 (S-END) and RV501 (T-END) on the DIGITAL board so that the respective peak to peak values of the waveforms on the oscilloscope are 1.2 Vp-p.

Adjustment Location: See page 23. FWD Torque Adjustment Adjustment Method: 1. Enter the Test Mode 2 (Torque Measurement Mode) (see page 19.) and set the torque meter TW-7131 (8-909-708-71). 2. Press the PLAY (�) key. 3. Press the ) key or 0 key and adjust so that the FWD torque value (T side take-up torque) is within the range of 11 to 13 g�cm. 4. When the torque meter is circulating around, check the indicated value.
REC MODE
4. Put the REC MODE switch to the LONG (ATF: OFF) position and put the REMOTE switch to either the WIRED or WIRELESS position (OFFSET: � or +), fine adjust both the S1 guide and T1 guide so that the RF signal waveform of the oscilloscope repeatedly contracts and expands in vertical directions as it has the same shape.
* Adjust the direction of tightening to complete this adjustment. If there is curl on any of the upper and lower flanges of the S2, T2 and F guides, adjust the guide of concern.
