Hi I have a DM500S which has been happiliy working for the last couple of months. It is using Gemini 4.6. Last night I was watching a channel when the picture froze. I tuned to another channel and back to the same channel and got the msg "Service not found". I tried other channels but just got the same msg. I power cycled the box and the green light on the box came on but faded slowly and there was no display. I changed the PSU for a spare one I had lying around, same voltage, and the power light stays on and I do get an image on the screen but the picture is like a badly tuned TV, black and white, rolling and distorted. There is also a hum from the power connection at the back of the box. I can stop this if I play with the power connector. On the screen I can just about make out the GP logo and part of the screen showing TV system and PAL. My TV is PAL so I shouldn't be getting issues with a rolling picture unless something on the DM500 has failed. The box was connected via scart, I've tried the component out and get the same issues. No matter what I seem to do I can't get the rolling to stop. I'm guessing it has failed. Does anyone else have any ideas?
