Hi all, looking for a little help if possible. I have here 3 Neo Geo CD's. Two have completely dead mobo's and were bought as faulty for spare parts (previous owner tried to install a unibios and damaged pads and the board). I have bridged tracks and pads but they are dead. The third one the board works fine. I don't have an original PSU i am using an external HDD psu (not one of the cheap chinese molex ones) that gives out 5V@2A, 12V@2A & Gnd, the original psu socket was removed and a 3 pin din socket was put in its place. The console boots up fine and will load a game disc fine, i can then play or leave on rolling demos for hours and it will be fine. After a little while though it all seems to give up, if i turn the console off and then back on the disc is detected and i get the press start flashing but every disc shows the loading progress bar and then black screens. this is the same until i turn the unit off for a little while and let it cool down. I thought this may be a laser issue so swapped that out, same thing happens, can play for a few hours and then everything boots to a black screen. Tried a different drive controller board, same issue. I have tried another video.power board and again it boots fine and plays but then gives up again.
Anyone have any tips that might help?
Thanks
