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.
No! the problem is in the LCD panel display, behind the LCD is a large circuit board that process video, colour, brightness, and balance, if that goes wrong it throws the colour content off, replacing monitor best option. But first it would be a good idea to sub the video cable from the monitor to the computer to cover everything and hook a spare monitor to the computer to rule out the video graphics card.
If you mean that you used an older monitor to test the computer and it worked and you think the monitor mentioned is failing, it is probably worth getting it checked by a tv repairman who can advise you whether it can be fixed. Generally, a monitor that refuses to show a picture, cuts off after being powered on, or has a display that is poor or with a colour cast is probably NOT worth fixing
Video-cards generate "primary" colours (red, green, blue), and "mix" those colours to produce millions of "secondary" colours.
First, try replacing the "data' cable between the LCD and the video-card.
Second, if your LCD works correctly when connected to some other desktop or laptop computer, then the video-card in your computer is not working properly -- not sending one of the "primary" colours to the LCD. Replace the video-card.
I fixed it myself, it seems that the monitor have some problems remembering it's settings and sometimes it automatically set its settings to crazy values that are out of the range that we are allowed to input. For my case, the setting that was crazy was the gamma setting since it was set so high. I wasn't able to bring it back to a normal setting so I found a way to do it by resetting the monitor. So to reset these display settings such as colour, contrast, brightness and gama, you need to turn on the monitor and unplug the monitor without turning it off and plug it back in again. It will automatically power on and the correct default settings will be present.
there are 15 Pins in Monitor cable which is connected to VGA port on the rear side of the Tower. First, we need to reset BIOS settings, and then try again - onboard video card only. for Add-on Video card try reseating video card in diff. slot if possible / reseat video card and try again. if it does not fix it, it could be the problem with Monitor RGB Connection - near the electron gun in the monitor CRT tube. resolder RGB , it will fix it.
