it is fault of cooling system, and sound output error, if fan is disconnected or not running F61 comes on screen then nothing happends, power sound ic is the main cause of the device, not only cleaning works, may need to change the the power sound out put ic.

The F61 indicates a problem detected in the output amp stage and the unit us shutdown to prevent further damage. If you can supply the model number, I can give you the part required and the approximate cost.

I can not find a listing for model SA-HT545. All I can suggest is that there should be a large black IC attached to a heatsink that should be marked STKxxx or something similar. Post that marking here and I'll confirm that it is the correct one to replace. That part is the output amplifier pac and is the most common failure part that generates the symptom you describe.
Keep me posted.

F61 is a problem with the output amplifier pac. It is the equivalent of "protect" mode. The output pac needs to be replaced. I'll look up the part number for you.

Typically the F61 error is a protection error indicating that there is a problem with the output amplifier section. The failiing part is usually IC501 (part number RSN311W64D) which costs about $95. Have this unit checked as there are other possibilities.
