F61 APPEAR ON MY PANASONIC SA-HT740, HOW TO SOLVE THIS PROBLEM, IT START AND SHUT DOWN IN LESS THEN A MINUTE.
BEFORE I WAS CHANGING THE SPEAKER CABLES.
You possibly took out the output ic by crossing speaker wires or touch one to the case when the other was in the terminal. (turn off and unplug when moving speaker wires)
Before taking it in remove all wires unplug power cord wait 30 seconds and plug just the power cord and turn on. If it still goes to f61 it's going to most likely need the output ic replaced.
$70-90 labor and about $100 for the part.
SB-WA730 5 disc DVD player Home Theater with F61 error. I took apart sub-woofer and inspected power supply. Found a burn't trace (flat conductor) on circuit board.
Possibly due to a storm/lightning strike or power surge issue from using generator.
Will repair the circuit board trace to see if it is a fix. Will report back if it corrected problem.
Two IC's as mentioned in other forums STK470 090 (voltage regulater) & RSN311W64 (audio power module could be blown if speaker leads touched together..bad design!!) were found on eBay and wil be next step.
