All power supply voltages are ok but still no power LED turns on and set remains DEAD. What could be the problem?

It doesnot turn on either with power sw or with remote control. Some problem in main board . I have not yet received the schematic to check micro IC viltages.The green or Red led also not turning on.

I have tried to clean and heated the main pcb with hair dryer.Surprisingly the set started working. It worked for 10 minutes and suddenly Volume OSD appeared on screen then the set Hung. No switches were operating. No remote operation.I turned it off by pulling power cord,then now it does not turns on.
Back to step 1 again
Any clue?
