1) When did this problem start ?
2) Did you make any changes (OR) whether any changes were made around the vicinity of your computer location ?
3) Is there a pattern of colors in any particular corner of the screen ?
3) Please provide with any additional information you can.
I didn't change anything.
There is no such colour around the corner.It's OK.
Screen is just jumping with lots of horizontal bar as TV screen shows on low voltage.
Sorry I don't know whether your problem was solved or not.
But the problem you stated is nothing but just a dry sold problem.
Check that when you hit your monitor from any side then sometimes its screen becomes clear and then again became in the previous condition.
Check the Sold on the circuit attached just behind the CRT, I don't know its name but check it out.

If the monitor flickers, it has to do with the refresh rate of the monitor, go into your monitor properties and adjust and apply until it fixes it, if that doesnt help at all then its a component failure inside it physically, and that means you need a new monitor
the last time I use my 15" LG 500G works good. but suddenly the screen turns black but the light green power still on. what happen to my screen? is that horizontal and vertical circuit`s problem?
thx alot for helping out.
