Manual is actually a pack of schematics, good quality pictures.
;
Great service. Manual delivered at a great price. Reliable delivery service. They have a great selection. A recommended service!
 ;
I used your service and I found myself well I need service manual teac v plate 770 and I was able to access and remove the belt that erno routes. thanks I recommend it to all
;
At first I thought there had been a mix up as I required the service manual for the cassette unit and the one supplied was for the CD unit. However when I scrolled further down I realised that both had been scanned together! This enabled me to dismantle and repair the cassette unit as intended and I also have a copy of the manual for both the CD and graphic equaliser units should I ever need them. Thanks very much for a great service.

Excelent service, the manual is complete, very cheap and fast

MD-MT80W/90W/90/90C
� The spindle motor fails to run. Does the head move
Does the waveform appear on the IC201 pins 24 and 25 after TEST mode AUTO2 completion and in this state? Yes
No
Check the IC201 periphery.
Does waveform appear on the IC601 pin 43? Yes Does waveform appear on IC901 pins 1, 2 and 23? Yes
No
Replace. IC601
No
L608, IC201, IC901, CN601 and flex, etc. soldering check
Replace the spindle motor.
� Recording/playback operation
Insert a low reflection disc, and ascertain audio output by normal playback, and then set TEST REC mode. Does the head move down, failing to start record even when the continuous record mode is set after address? No Does the RF waveform appear at TP201 (When monitoring the RF waveform, set to MSL:80H using the control setting item of EEPROM) when recording/Playback is performed No Does level of pins 86 of IC401 and pin 17 of IC101 change depending on record and playback? Yes Yes Yes Check voltage of pins 52 and 53 of IC201, pins 3, 4, 7, and 9 of IC651, pins 1 and 2 of CN601. Check whether disc is recordinhibited.
No
Check periphery of IC401 and IC101.
Is RF pattern output from IC201 pin 50? Yes Check whether there is any damage in IC101, periphery of laser diode. Check for defects of IC351 in head drive flexible PWB, head, flexible PWB.
No
Check for soldering failure of IC201 .
Is audio monitor output given in normal mode LINE IN record? No
Yes
Check waveforms of pins 8,10,11,12 of IC501, pins 70 to 73 of IC201.
Is waveform obtained on IC501 pins 2 and 3? No
Yes
Check whether the pin 13 of IC501 and the pin 59 of IC201 are in H state.
Is audio waveform observed on the pins 8 and 17 of IC703? Yes Check whether input waveform is observed on the pins 4 and 21 of IC703.
No
Does voltage on the IC701 pins 13 to 15 change in case of record VOLUME UP/DOWN?
