Hey guys so I have a PS3 slim and I've tried everything to get it to work. It doesn't have video in either HDMI or AV. There is sound when I connect it using AV cables but still no picture. I've tried the two beeps restart and tried to enter safe mode through 3 beeps. Nada. Now I believe it has to do with the GPU which when opened looks to have overheated a little. There are slight grayish "burn marks" in the corners so should I reflow it? Will it work?
