My monitor was fine for about 2 years then suddenly one day it has a lot of flicker and color swirls on the entire screen. Looks similar to the vertical hold on a tv being messed up (similar). Twice it eventually went normal, but then messed up again after it went to sleep or off and back on. Any ideas?

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.
Check the cables, connectors and connections.
Take it to a repair shop.
Welcome to Fixya Support,

Monitor Flickering May due to following Reason
1. Deffective LOT
2. Deffictive Filter IC or Deffective horizontal IC
To fix this issue,you have to check LOT, if LOT working fine, you have to search for burn out capacitor along with filter IC and replace with new one. After this your monitor must work properly, without any flickering.

The easiest thing would be to check your cable for a bent or loose pin. Next put another external monitor on the laptop. The circuitry to provide video to the laptop screen and the external monitor are separate except that they share a video processor and video memory. There can be bad electronics involved.
maybe ur screen was put into a lot of magnetic interference. so check for any magnetic rays emitting devices like speaker adapters etc. a simple check would be to degauss( its in the screen properties).
