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.
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
Most of the time it is due to a hardware issue like a video card or the screen itself.
When does the line appear? A. Is it there even with the monitor or laptop turned off? B. Is it there during the OS logo / boot screen or does it appear after the OS loads? C. If it is a monitor, with your system turned off go into the menu of the monitor by using the buttons on the front. Is the line there?
What you can do to try and fix it is.
1. Make sure you have all the latest drivers for your video card. 2. Change the resolution of the screen. 3. Change the frequency of the monitor.
If these do not fix your issue you may want to look at getting or borrowing a video card and replacing it if this system is a desktop. If this system is a laptop and the above does not fix the issue your best bet would be to put up with it or buy a new laptop to be honest.
you're video card is failing, try the secondary port if you have one, artifacting such as different colors, shapes and lines are VGA related, you need a new VGA card and for more info contact http://tinyurl.com/m7ghqz
