Question about Dell UltraSharp 1704FPT 17" Flat Panel LCD Monitor
I have 3 of these monitors that also shut down on their own.
Two will not turn on at all (no response from power button)
and the third will work for a short time
then the top of the screen gets brighter then shuts off.
It is possible to turn this monitor back on but it will only stay on
for a second or up to about a minute.
It is not the power cord or video card. Old CRTs work fine on the
computers and the 1704 monitors have been moved to different computers
and have experienced the same problems.
Do all LCDs have a much shorter life than CRTs or does Dell have a
problem with these products?
Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After they shut down on their own, you check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
