Sanyo dp46848 Power Surge Blues Can't Post

a sanyo dp46848 went through a power surge and was given to me for free..

Upon plugging it in, there is no flash, pop, hum or anything. When i press the power button a green light comes on for about 5-10 seconds, there is no screen flash or anything making a sound, nothing but the green light until it goes out.

I bought a used power power board 1AV4U20C32500 for 8 bucks (which could be bad itself) and it didn't change or fix anything, 5-10 second green light, nothing audio or visual on the screen or the TV.

I have an analog ohm meter and can check points but i don't know which ones to touch on this board.

I'm thinking a new Sanyo N6EE (1AA4B10N21300) Main Board for DP46848 for 39US or the Backlight Inverter master..

Any help or observations is greatly appreciated!

CN201 voltages? Especially pin 7. (STB5V)

See if there is any difference between measuring for a voltage when set has been connected to AC mains and once Power button is pressed. Standby versus ON (Run)

Power/Inverter board.

I thought you said you swapped? You didn't examine either board? Board is well labeled.
