Any suggestions? What are the part numbers for the power and main board?

yes,veryry possible you have a bad transister on the power supply board .best way to fix it is to change the hole board.
SOURCE: tv won't power on, stand-by light blinks 6 times continously
just unplug tv 5 minutes. and plug it again. power on again. if not reset tv.
SOURCE: samsung lcd tv le40r8. tv will not switch on.
The problem is the mainboard tried to turn on TV but failed due to internal circuit problem. Normally, the power supply board is malfuntioned.

Hi
Thanks for using FixYa. Please check the following—
1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a
multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an
IC tester or an oscilloscope to check this IC.
After checking this if it still doesn’t
work then check P3 D-sub Input (on the D-board). See this schematic for
details--
Please do accept the solution if the issue is resolved or else revert for further assistance.
Thanks
Rylee
