Audio Systems: Problems with my panasonic cd player, panasonic cd player, output transistors


Question
My panasonic SA-AK340 has stopped working. It displays F6I on the screen for 2 seconds and then shuts down. Please help.. thank you.

Answer
The model number you gave is for an HES system.

It is probably a power supply system failure, but, quite frankly it could be from many or several causes.

Another common cause of failure is shorted down audio output transistors in the power amplifier section.

You will need to have a tech troubleshoot using a voltmeter and checking the voltage operations throughout the unit to find out the exact cause of this.

I would guess the cost of repair to be in the $100 area plus or minus, depending on the final result of the diagnosis.

Hope this helps.

PS:  Make sure, first off, the speaker wires do not have any shorts or breaks in the insulation and that you have reset the system.  (You can reset it by unplugging the power cord for 1 hour before powering it up again).
