Question about Yamaha DSP-A3090 7-Channel Amplifier

1 Answer

DSP-A3090 Parts list

Does anyone have access to this? It'd be nice. Seems to me that the three main problems with this model are the power supply, source knob, and the display.

If we can find a commonality among the power supply problems, for instance, maybe a quick repair guide could be established.

Hi...
Is the first set "stereo" settings and the 2nd set "surround" settings?
If so that may mean that the surround speakers arent all connected right.

Yamaha DSP-A3090 7-Channel / Power + Volume Knob Problems


Hi james, Hard to pin down a diagnosis of the problem without having a looksee under the hood. Good amp, worth repair, if you are into it. Could be a number of things
  1. Loss of a rail in the power supply
  2. System Processor down
  3. Main power transformer faulty
Are you able to check over the amps power supply? Need to start there to sort out the problem. Good Luck. Get back to me here if you want to get into it further

regards
Graeme

Yamaha DSP-A3090 sound problem when viewing movies


Sounds like a cold solder joint around the imput to the power amp stage on the board. If you can get to the board take a bright lamp and a magnifying glass to chek for solder joints that are frosty looking .If so heat them up and dab solder to make them shiny.
Good Luck
