Help

Recently joined and got great help fixing my Cambridge audio 640c so I thought I'd try again. I have a Panasonic sa-xr15 AV amp which started showing fault code f76 and switching off. It would turn on again but only for a few mins. I disconnected everything and then reconnected. It worked faultlessly for a few days and then blew the plug fuse. I've taken lid off and nothing obvious burnt or damaged. Has anybody got any ideas if this is fixable? I have basic soldering skills. Any ideas very welcome.

can you find out exactly what fault code f76 is?

maybe check with the gang over at diy forum?

Find and visually check the power supply board in the unit. Look for crowned (bulging) and/or leaking capacitors. Replace any bad ones you see, remembering to observe polarity and discharge the unit. Unplug and press the power switch before letting it sit for at least 8 hours (overnight is good). That's a good place to start. Hope this helps.
