I have one SA - EH700 which is 20 Years Old. It used to work fine but last time I've opened up the main amp. The control board was malfuntioning for those old switches. But during soldering out the bad switches , I accidently broke a 6.3v 100?F capacitor. I replaced the capacitor with same rating but my amp goes to fm mode after starting and the Mixer Tuner "SA - EH750" don't power up or sometime it powers up with wrong light patterns. (System Crash Type). I don't know what to do. Can someone help me out please?

Here is the troubleshooting section of the guide. It points to several things for you to check.

See no response when any button is pressed. Oddly, it might be condensation.

The SB-WA350 is the sub-woofer for the SC-HT900 home theater system. See the manual here at Panasonic's support page, https://shop.panasonic.com/support-only/SC-HT900.html , or ManualsLib, https://www.manualslib.com/manual/266877/Panasonic-Sc-Ht900.html?page=2#manual . The manual lists the system cable as part K1HA25HA0001.

I've found the cable listed at E-bay and here: http://salestores.com/pak1sucak1ha.html . However, Panasonic has discontinued the SC-HT900 and the cable is out of stock at most vendors. I hope this helps.

Not so much an answer more a shared problem with a slight insight. On the Panasonic manual page 40 http://www.panasonic.ae/EN/Manuals/SC-PT550%20-%20850W.pdf
It states the following: This unit can decode the surround signals received through cable TV box, digital broadcasting or satellite broadcasts. Refer to your equipment’s operating instructions for details. Only Dolby Digital and PCM can be played with this connection.
So it sounds like the SA-PT850 unit will decode DTS from an internal source ie DVD but not from an external source ie ps3 or WDTV which is a shame because I own a WDTV. The solution for me is to convert the dts to ac3 (Dolby digital) which works great. But not sure if this is an option for you.

Since you are going into Overload (and back out again) it sounds like the MOSFETs might still be good and are shutting down before any damage has been done (as designed). The fan is a normal 80mm 12vdc computer case fan. You could easily try swapping it out.

The F76 message indicates a fault in one of the internal outputs on the power supply. There aren't any settings or resets that will fix this, and the Panasonic will require service.
