This manual is accurate and of high quality. It is only volume 2 of the service manual. This is schematic, parts lists, and exploded mechanical drawings. The theory of operation and the diss-assembly instructions are in volume 1. The unit can be tricky to dis-assemble portions of so the volume 1 manual can be important. The product description of the manual is accurate but it does not say anything about volume 1 and the image of the front page does clearly say Volume 2.

Wellll again thank you very much fast and effective. Clear and well done for such an old TV!!!!

It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.

Set the handset in the NG test mode 3, check whether deviation of the TX data is app. 9.0 kHz Dev.
Check whether there is a NG 250 Hz data waveform at RT602. OK Check handset RF section.
Check R668, R712, R713, R716, R717, C719, C748 and RT602.
OK Set the handset in the NG test mode 6, 926.997467 MHz (250 Hz ±8 kHz Dev.) 1mV output signal from RF test point is applied. Check whether the bell ring. OK Place the handset on the base to charge about 5 seconds, then connect again. Check whether the 250 NG Hz data waveform from Pin 9 of IC603 is fed. OK Check IC603 and its peripheral circuit. OK NG Check handset RF section.
Check whether there is a NG 250 Hz data waveform at Pin 10 of IC602. OK Check whether there is a NG 250 Hz data waveform at Pin 40 of IC608. OK Check IC608 and its peripheral circuit.
Check IC602 and its peripheral circuit.
