Hey guys just spent 3 hours searching so I figured I'd finally post up. I just bought a D3 that supposedly had a map disc error (I've fixed this on a few pioneers). It came in today and the first thing i did was of course wire it up to my test bench. Unfortunately as soon as it powers on it goes to a grey screen and never boots past that. None of the hard buttons work and i've tried resetting it multiple times. The screen flashes to a different color grey about 3 times but doesn't do anything else.
If anyone knows what to do or can help I'd greatly appreciate it. I've looked into repair costs and if I can't fix this is 130 a fair price? I bought the unit broken for 70 dollars and got a free avh-p5700 with a calibration issue from the seller.
