HP 1730 blank while power on

[Azagtoth]

I have problem with an HP1730 which turns of by itself after aproximateley 10-15 minutes.Had some bulged caps on power board, and i remove them , put new ones but problem persists!I checked also logic board (has Benq logo on it) and everything seems in order.i also checked for dimmed screen, but no image at all.It simply turns itself off while power led is stil shining continuously.
If there is any solution please suggest...im out of ideas!
Thanks in advance!

Replace all the caps not just the ones that where bulged re solder inverter transformers
you may have bad CCFL bulbs. test CCFL bulbs could be useful. Pictures of power board and logic board would be nice.

you can check all caps with LCR/ESR meter if you have, so you can easily find the bad caps like high ESR but low value.
