      Hi mate,

      Yeah it comes on when I eventually get it connected, but it is all blurry and unreadable. I think it is defo a power issue on the board.

          No it does not show up, it's like the Flash chip is corrupt!

              Another good suggestion. Tuner is out and the only thing connected is the lcd. Still the same issues.

                  I have tried about 10 different power supplies as I have a load of DM500's. They are the exact same. Still no joy. Do you know where I can get a schematic of the mainboard?

                            Take the top off and check the 4 big electrolytic capacitors have flat tops. If the tops are at all bellied upwards they are stuffed, I would just replace them anyway whether they look naff or not.

                            These boxes are just way too small to get rid of the heat that they generate and the electrolytics dry out really fast. Your symptoms are exactly what will happen when they are heading South.

                              I thought dreamUP was clone safe. I have always used it and it has been successful in the past. Can you suggest others and where I can get them. I will try anything now to get this box up and running. Cheers mate.

                                Thanks for the reply mate. Where would I get replacements?
