Akai LCT2715 power supply repair?

[miniman82]

Duh, should have looked at the board closer. There's a pin marked "on/off", putting 5vdc on that made all the other voltages appear like they're supposed to. So the power supply is fine again. Still no light on the screen, the green light in front comes on for like 30 seconds, then it turns orange and stays that way till I cycle power. I think the main board is probably shot, considering the power supply is now fine. The little PC mount fuse for 12v is still good, and there doesn't seem to be any shorts anywhere. Anything else I should check?
