Hoo kay - got me one dilly.

A pal's 4700. Locked with an AR105B. We can't get any atmega128 to work in this puppy. When I remove the atmega, I will read and try to verify the eprom, and we get a butt-load of errors... so something is corrupting the atmega as the receiver powers up.

Anyone have an idea where we can start looking? (I'm thinking the lock..as when it's in ON, this receiver will lose Sat signal)

Update - STILL have the black screen, but fixed the lock/sat signal problem.

Receiver has currecnt firmwear... and I'm bumfuzzled.
