If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.
Testimonial: "I found the problem. Was on VGA cable. These cables from PC to monitor should not be close to any electrical cable and should be attached on PC and monitor very good. If that is not the problem then I recommend to buy one new cable and try again. That is the cheapest solution before you waste your money taking your screen to a technician!"

There are a couple of reasons for this problem.
1. The screen resolution was set too low. Try 1024 X 768 or higher.
2. If you cannot change the screen resolution then the video driver was not installed or the wrong video driver was installed.
Testimonial: "Exactly right! Thank you. I think I may have a Trojan changing my resolution...will work on that problem next. Thanks so much for the help!"

The native resolution for that LCD is 1440x900. If you do not see that resolution in your display properties you can try to update the video driver. If it is still not displayed as an option you may need a newer graphics card. Many newer low end card support this widescreen resolution, so if you need to replace the card you will not need to spend a lot of money.

It is probably the power supply, or the inverters.
Similar problem with solution, though it requires you to know something about electronics.

The problem can be bad power supply feeding the backlight inverter circuits due to bad caps, or in the inverter circuits, or worst case will be bad lamps, you need to open it up and tell us what you see inside first, good pictures will help, see example of failed VIEWSONIC due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Check the two insertion ends of the power cable and ensure that they are well fitted in. Check your area power voltage range and ensure that the monitor complies with specification.
Make sure you are using the right and GOOD power cable.
Lastly, Unplug from the monitor from the system and allow to cool for a good 3 hours or better still, disengage it from duty for 1 day and start using it the next day.
Do you have enough ventillation there?
Don't forget to rate me and get back to me if this helps. Tnx.
