Marshall 275 AVT Problem

[spongebobrob]

Hello,

Was jamming the other day and all of sudden the amp just went dead.

The amp will switch on but then i cannot press in any of the buttons (OD 1, ac sim, Clean, OD 2) so can't get any sound out of the amp.

I'm guessing the problem is a blown fuse. Theres also a strong chance I have far too many electrical equipment items plugged into the same socket.

How do I go about repairing this problem? Hoping its a simple DIY..

Thanks in advance for any help. I have pretty much zero technical knowledge when it comes to this kind of thing.

Cheers,
Rob

If NONE of the buttons will light up, you most likely lost a low voltage power supply inside. If you can't use a voltmeter and solder parts onto circuit boards, you best refer this to a technician.
