Hyundai U90d no screen flash at all

[dmbj]

The Green Power light will come on and then go to amber. The screen never flashes on at all. Supposedly this monitor was used for about 3 weeks. and then sat on a shelf for months. IT was made in may 07.

There is a burned up ic on the bottom of the board and i have no clue how to figure out what it was, or what would have caused it to go bad.

FYI: the 12v on the inverter is steady at 11.97v and the 5v is steady at 5.05v There is no 3.3v on this board that i can find.

Any Ideas guys?

not a very good picture but its probably a mosfet, one of a matching pair the other one is to the right of it, one for each transformer

I agree. The burned up (left) is mirrored on the right. See what part number is that and you will know the part no. for the burned up.
