Sansui AVR Repair needed
« on: July 11, 2018, 10:06:05 PM »
Hello

I have an older Sansui AVR which after a random time of use around 10 minutes makes a horrible screach and shuts off the speakers,, Then ok for a while after turning off and on again.
Blowing a fan on a heatsink/board near the top through the vents seems to reduce the frequency of the problem.

Is there anybody that can do repairs at a worthwhile cost? obviously this amp is not worth a lot and not worth spending more than its value fixing it.
I am ok with repairing electronics myself too if I can get help troubleshooting the issue from somebody that is knowledgeabile on these amps.. I have already replaced the voltage regulator on the small heatsink that I was cooling, but still have the same issue.

Thanks,
Don

Sounds like you've been playing around with this for quite a while in it's current state.  Not sure what speakers these are powering but I would refrain from use until the issue is sorted, so as not to risk potential damage to your speakers.

Assuming this AVR is pre hdmi you are likely to buy an equivalent or better amplifier used  for the cost of 3 hours of skilled technician labour.  Sansui has been brand engineered (badged) Chinese stuff for 15 + years. 

I would buy a used yamaha Denon marantz or even Onkyo and move on. 

AVRs are seldom quick fixes as they are more complex and harder to strip down.
