Re: main unit will not stay on
Check to make sure none of the speaker wires are touching the case. If not, unhook them all and see if problem persists. If it does then the amp is damaged. If not then plug one spkr in at a time and check to see which one is causing the problem.
The promblem could be that one of the two fans stops running. This causes a feedback response to the circuit system and shuts down with F61 error. Replacing the fan is easy and should not cost any more than £5

I found this link to the Panasonic DVD Home Theater Sound System SC-HT995/SC-HT995W. The Panasonic wireless system SE-FX61 works with the HT995W only. On pages 9-11 of the manual, it shows how to connect your surround speakers to the wireless SF-X61 unit in order for it to work. The SF-X61 unit sits between the rear R and L surround speakers (as illustrated on page 9 of the manual). https://panasonic.ca/viewing/ALL/SC-HT995/OI/rqt8766-1l/rqt8766-1l.pdf
This is a sign of a power supply problem. These units use what is called a "switch mode" power supply. These use a capacitor to kick-start the power supply. While I can't say for sure, this is the most likely cause. There are other components that can be close to failure later in the circuit that can cause this as well. Without seeing the actual unit and testing the circuits, there is really no way for me to know. You should expect to pay in the $20 range for parts for this repair.
the wires are color coded, follow the color coding on the wires, and connect the wires to the proper color coded connectors on the back of the main unit or go to panasonic.com to get the manual online for that model
