I am having the same F61 problem has anyone found any infomation on this if so email me. thanks

Hi there, I have just started having the same problem and was wondering if you have had any success finding out any info. Would greatly appreciate it if you could let me know. Many thanks, Lauren

I just replaced the STK470-090 voltage regulator chip in a Panasonic SA-AK600 with one I got from Best Buy per this site. The F61 error is gone but the heat sink gets way too hot after a few minutes of operation and the unit automatically turns on when I plug it in. Otherwise it seems to work fine. I advise anyone doing this repair to keep the lid off and power it up to check the temp of the STK470 heat sink before buttoning it up.

error message on panasonic sa-ak-600,what's my solution.
