Question about Samson SX1200 Amplifier
Both chanwnels appear to be good. ie. No blown output transistors, no speaker circuit shorts and nothing gets hot. Anyone have a schematic for this amp? Extensive searches have yielded no results for a schematic.
Have you checked the power supply section? Also look out for any IC's in the amp stages. They can go causing that kind of fault.

my friend resistors and diodes don't just go off your circuit without a real problem. those parts gave up because of shortage on your power section, i suggest that you check your power transistros first along with the diodes and resistors.
noisy transformers... hmmmm why is that making sound? the solution there is to dip the power transformer to a thick shellac varnish let it there for let's say an hour then let it dry for a day. then place it back in your unit and see if still sounds

SOURCE: one side of the amp
Either the channel on your radio is not working. Or the AV cord you are using is not working on one side (reverse the cord and plug it in the opposite you are using now. If it still only works on the one side your cord is good.) Or the final transistor for the channel on that amp might have blown. You could also have a cold soldier joint on or otherwise faulty jack plug. Let me know if this helps you find the issue.

SOURCE: My speakers stopped working
Heating of the power
can be one of the causes.
you may have to take out the complimentary pairs to check.
The pair may take out the drivers and some components along with it.
These may take some time, (troubleshooting)
But have a tech to guide you, if you need to DIY.
Good luck, let us know what you find or needs further assistance.
