Troubleshooting main board.


Three things to look for in service with LCD monitors,
1 bad capacitors
2 Bad transistors for the back light feeds
3 bad ic pulse chips for the Non function circuit
you will not find schematics unless you peruse the patent office records, reverse engineer the circuits and you will have a schematic
when the main chip fails on the vga board its time to buy a new vga video board,
sounds like your board may be suffering a bad IC telling the main chip the power is OK

let me know how it goes.
