Having problems with your Computer Monitors ?

LCD Monitor turns blank after 1-2 seconds

\015 Having problems with a Vision Quest 19'' LCD monitor VQL-19WSD 900W. My friend dropped this off as a spare. Plugged it in using the VGA and PWR plugs from my new I-INC 22'' LCD... (tigerdirect 179.99) Monitor comes on clear for 1sec and goes blank. Turning off/on, image re-apears for 1 sec and goes blank again. Running AMD phenom2 920 -w- windows vista 64 bit Nvida 9400 graphic card, 4GB Kingston Mem @800MHZ..Not sure if vista supports this monitor. Spoke to an LCD repair guy across town, but he wouldnt expand only to say it's a commom prob and he can repair for 40 bucks or less, prob is the hour drive each way x2. I've searched thru the archives at this site for similar probs, only to conclude from the Pro's comments it must be either the backlite or pwr supply. Any insight to this prob would be greatly appreciated. Thanx in advance.\015

Answers :

Yes, this is a very common problem. Often times it is the inverter capacitors that wear down (they look like small batteries with a white stripe and are close to the transformers). If you can get in to the circuit boards, these capacitors are often visibly swollen on the tops; they are normally flat with an embossed X.

If you are going to replace the capacitors, pay very close attention to which way the stripe is; if you reverse this, the capacitor may explode.
We are reluctantly trashing our second 19" VisionQuest monitor, same problem as the first one, black screen on both our XP and VISTA. The company replaced the first one under warranty, no such for this one. Anything besides money for repair recommended?
