Having problems with your Computer Monitors ?

Viewsonic vp171s lcd flickers on start up then goes black.

\015 Viewsonic vp171s lcd flickers on start up then goes to a black screen. Took tower and monitor to computer repair shop and the tech varified it was a monitor problem and not a pc problem. PC worked fine on tech's monitor. My husband then took monitor apart and blew in some canned air and when it started it displayed normally long enough in the boot up process to get to Microsoft's request for password, then it went black and stayed black.What might be the problem and how do we fix it? Where do we get parts?Computer tech said it wasn't worth paying a repair fee that we should buy a new one.Is that what you say too?Sue\015

Answers :

This is typical of a back-light problem, especially when you view the LCD screen at a sharp angle and you see a dim Windows image. This fault is caused by either a faulty inverter board or a faulty CCFL lamp.
\015\012The inverter supplies high voltage to the CCFL lamp. the CCFL lamp is a mini fluro lamp which fails with age and use.
\015\012This LCD screen can be repaired, the cost of an inverter board and CCFL lamp is a lot cheaper than a new LCD screen, but this is an opportunity/excuse to buy a larger size LCD screen as these monitors have dropped in price.
