Hi all!
My Onkyo TX-SV353 is almost died last week. The front panel buttons and the remote controller are not working anymore. Any button I push on the front panel has no effect, and if I try with the remote controller, the led on the front panel blinks but there is no effect on the sintoamp.
I've already tried turning on while holding video-1 button and then speaker-A, and the panel displays "CLEAR" and reset. But the problem persists.
I've looked inside at the PCBs and I don't find anything burned, as far as I can see.
Have you any suggestion? Anybody has the service manual of that unit?

Thank you very much and greetings from Italy Wink

After a better lookup, I've found that the capacitor C701 on the front panel PCB (NCDIS-5871) is defective (the electrolyte appears out) . But, I'm unable to read the capacitor value (it's "button" form). Anyone knows that? The schema could be helpful....
