2 seconds to black samsung syncmaster 931bw

[momceras]

Hi electronic geeks,

I have a syncmaster 931bw with th "2 seconds to black" synthom.
Replaced 4 caps hopping that problem be fixed that easy, but not.
Since I don't have experience with this problem I was hopping the you guys could point me some directions. I was looking for the next step replacing the inverting but it will take too long to arrive (4 weeks aprox). Meanwhile should I try anything else ?

I would check the High Voltage windings resistance of the inverter transfomer, and also make two test lamps: https://www.badcaps.net/forum/showthread.php?t=19987
Please also upload good clear straight shot pictures of the bottom side of the board.

Thanks budm,
I have tried with other lamps with same result. I ordered the inverter today expecting to get it in 3, 4 weeks. Also have resoldered (forgive me if this is not english) some of the contacts on the bottom side. Since theres is an image, even for few seconds, and there is image I supose the problema would be on the power board. I pointed a flash lighht and I can't see any image.
