Defender - no sound

[chubsta]

Played defender this morning, all was good, came back to it a few hours later and there is no sound - any ideas on what to check, bearing in mind i am crap at this stuff..

Worth checking the fuses / holders. There's 2 on the sound board itself.

If fuses check out, try swapping over the volume control and speaker connectors on the sound board. If you listen very closely you may hear pre amp volume coming through the speaker. In which case you probably have a dead TDA2002.

No luck so far - still not working this morning, checked fuses and switched over the cables, couldnt hear anything at all. There is power going to the speaker because i get that hum you always get when the sound is right up, but there is nothing when i press the test switch on the board. Unfortunately i cant run through the cab diagnostics as i am waiting for a new set of switches to arrive

Small update, remembered i have a similar soundboard in my Sinistar so jumpered that up correctly, stuck it in the Defender and it worked, so the board is definitely bust, at least that narrows it down a bit, now all i have to do is find out exactly what is broken!
