Denon AVR 3805 picture problems

[Drummo]

Everything worked fine when I first set up the amp however some strange things have started happening.
1. The AMP turns off for no apparent reason.
2. The picture for the video player starting going all fuzzy. I thought it was the video heads, however after a service the problem still occurred. Soon after I wasn't able to get any picture at all. I disconnected the video and put it straight the tv and it works fine so the problem must be the amp.
3. The amp is 'live', if you touch the outside there is a minor tingling like a very small electric shock.

I bought the unit in Singapore and brought it back to Australia so I'm not covered by any warranty.
Any idea's.

Thanks

It's a shame you don't have a warranty, cause I think your going to need to take the receiver in to be repaired. There is definitely a defect with it if you get a shock whenever you touch it
