Just found this one on the garbage yesterday : )
Well, as soon as I turned it on, I noticed a burning smell so opened it up and noticed the 2 resistors "cooking".
I would like to ask you if you think this might be solve by direct replacemente?
Also, anyone has a service manual / user's manual in english they could share in pdf?

I checked the surrounding transistors and, since I don't have much experience, I've been reading around and retained that:
b-e should conduct in one way only;
b-c should conduct in one way only;
c-e shouldn't conduct either way.
I measured the transistors (still on the board) around the faulty resistors and most of them measure faulty.
If they are indeed faulty, what might have caused it? what shoudl I check next? _________________ Best regards,

Typical signs of water/fluid damage.
Very likely to be more problem that it's worthed. |
