UNTIL IT IS SWITCHED AT NIGHT AND THE SAME THING HAPPENS THE NEXT DAY. HOPING YOU CAN HELP THANKYOU.\015

Answers :

If you can check your monitor with another computer, that would be the best inspection and make sure that the problem is from LCD monitors. The following steps are how to check what wrong with your monitor.
1. Power on both CPU\015\012and monitor. After it goes off, you have to\015\012check that if you can see the image on the screen or not by shining a\015\012flashlight into the\015\012screen, not directly but find the best angle to the screen and take a\015\012look very\015\012closely.
2.If you can see the icons or any image, there will be a minor\015\012problem. I used to check my LCD monitor and could see window image\015\012using flashlight and found out that Some\015\012of CCFL lamps inside were broken and it is very easy to replace.
3.If you\015\012cannot see anything on\015\012the screen, there'll be some problems with inverter board. If you have\015\012soldering tool and want to fix it by yourself, check the caps first. It\015\012may\015\012cause this problem. Some caps might show leaking or burn spot on the\015\012board\015\012because of too high temp. If you don't have soldering tool, you better\015\012go get a\015\012technician to do so.
Thank you,
