bad news indeed hehe no warranty somemore its a arb unit, maybe send to someone try to see if its fixable or not
Hmm.. Check if it's the cable or interface that's malfunctioning. Switch to a different DVI port, and if that fails, swap to a different DVI cable?
I am putting my money on the fact that the interface cable (usually some sort of ribbon connector) from the digital input to the panel itself might be loose or ineffective. Doesn't hurt to have a crack at it and try fixing it.
