Hai Bill and others,
I hope I didnt broke any rules by contacting you directly, I did search for the subject as aboved but nothing related to my situation. I need your advices.

This hp 2033sw has a ploblem as I ON the set, the display look fine and the bios display ok it moved around as normal set, but after few second (let just say 10 sec) the set went blank. I did put a testpen on top of the hV trans on the inventer brd and the testpen light up, to me this an indication a present of hv there.
please advice me what went wrong. I did change all the ecap on the psu brd and the AD Logic brd.

Thank you bill.
Attach pictures. This sounds like 'Two seconds to black' comment by bill.

Did you hookup a working computer to the LCD? If not, most monitors will go to sleep if there is no valid signal.

If you think it is 2 seconds to black, the most likely problems are

a) bad caps
b) bad inverter transformer
c) bad ccfl and/or wiring

All the above are documented in more detail starting with post #13 an #14 at

Also note the misc suggestion #1 on how to attach pictures using the manage attachments function.

Am I missing something? Is this an HP or a Samsung? Thread says samsung. Category says TV instead of monitor?
