Question about Sony STR-DE135 Receiver
My sony str-de135 receiver will not produce sound out of the left speaker. I switched the speakers to troubleshoot and think that it is the left outputs on the receiver. Can anyone tell me how to fix this problem?
Did the left channel work when u switched speakers, if so then the left speaker or wiring is a fault.if not then the output circuits on the amp are blown or the fuse is blown some amps have internal fuses in the output to protect the output transistors. unplug the power cord and take the cover off, look to see if u can find any fuses and check these for continuity u can hold these up to the light and u should see a fine filiment in one piece and not broken. these fuses sometimes blow just from age and use at high volume like a regular light bulb.If the fuse is blown replace with the same value else the output transistors will need to be replaced most likley along with the drivers.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
