crappie 1133- Keep us posted on what you find out. I have an Elite 7 HDI with pretty much the same issue as yours. Last time out, I checked the DI just as soon as the unit booted up and got some pretty decent images. A couple of hours later later I switched back to the DI page to check something and got nothing but a black screen. This appears to be a hardware issue, maybe due to heat, but it could possibly be a processor issue with the higher frequencies. If there is a software patch, I'd sure like to know. Thanks- M.
