I have an audio signal injector. Kindly see my previous articles. I have explained about the use of it. https://jestineyong.com/servicing-philips-tv-tester-808tvt/

Thanks for another great article, they are always very informative! I am new to these audio repairs, can you elaborate a bit more on how you “injected audio signals”?

Another set saved by you, but as you said: it´s not an original SONY

In reply to Parasuraman S.

Not only the cabinets but when one looks more closely will see other problems: a wiring harness badly executed, the power supply doesn't have a circuit board (the rectifiers are not seen, perhaps floating) and there is a misalignment in one of the yellow (or amber) circuit boards (as one can see comparing the relative position of the two boards). Anyhow, your repair work continues to follow the same way: fast, well done and effective. And with a good and technical writing style. Thanks for sharing (201!!!!)

Readymade cabinets are coming in the market like that. Anyone can easily make out that it is a local make. Sony is printed on it and not a sticker.
