Having problems with your Computer Monitors ?

Benq 937s monitor problem

\015 Thanks for your response on my monitor problem. I have looked long and hard at the electrolytic capacitors, but can see no bulging or leaking. Could they still be at fault or should I look elsewhere. I have had experience in soldering and the like so is not a problem to do, but I don't want to start pulling stuff apart until I am confident I have homed in on the problem. Any further comments?\015\012\015\012Thanks, Lucksafortun\015

Hi again,
\015\012They can most definitely still be at fault - here's where it becomes tricky. To properly test electrolytic capacitors you need an ESR meter - not cheap - or you could spend the $150 on a complete set of replacement caps instead. You're really rolling the dice either way, because it might turn out to be a bad transformer or something completely different. I've fixed 15-20 LCD monitors and the problem is almost always a cap, some are visible and easy fixes, others have stumped me for days and days until I just start replacing caps in the hopes of lucking out.
\015\012One of the things I tried when I first started doing it was searching google for the model number of the monitor to see if anyone else had fixed one and might know which parts were bad.
\015\012
\015\012Wish I could help more, sorry it didn't end up being an easy fix. Maybe it's worth calling the computer/TV repair shop and asking how much they'd charge to fix a LCD power issue.
\015\012
\015\012Best of luck,
\015\012Russ
