openbox dm500s clone

Hi, all my trusty dm500s clone has stopped working the green light on the front is there but no output to tv I cannot ping it from my pc it was running linuxsat support image by ten below I vaguely remember, but cannot remember the exact one its been running fine since i think year and a half, my brother was playing with it but not sure if he did anything to it or not, please help

i've checked the psu and its working will try dreamup thanks

Help just reflashed with dreamup which says it flashed successfully however still no output onto now my home tv any help please guys thanks dazzza

I fixed it, it wasn't the original image or the commando one I reflashed it with, it was dry joints on the scart socket resolderered them and a picture came up almost immediately,
One question though the new image is great with the proper working guide and it seems more stable with no glitching at all, I cannot seem to stream anymore to my ipad using dreambox live is there a different way of accessing it, even from the the web ui It will not stream on my pc with vlc, not a major problem just wondering if anyone alse can shed some light as I do like the newer image, cheers all for the help and suggestion Dazzza
