MY MONITER WANT DISPLAY PITCURE IT COMES ONWITH GREEN LIGHT BUT WHEN COMPUTER GOES TO BOOT THE LIGHT GOES TO OARNGE AND THEN LIGHT GOES COMPLETLY DIM

There are 3 things to think what can be the problem.
1. there is a day/night sensor on the dash.{not working properly}
2. there is a variable dimmer for the cluster illumination. loose connector or terminals.
3. The display itself.{can be defect} loose connection at the display or terminals.
lot of work.

Hope it helps.

Most probably caused by a power supply failure or main board short. Either way it is not a repairable fault.

This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:

• No Display, but Power Indicate light stay on green (Or Blue).
• Screen flash on and off and the power indicate light stays on green (or Blue).
• Dim Display

hori output Transistor maybe shorted you have no high voltage,so your Tubes are not lighting.

hi, hook up your old one and change the refresh rate to 60 or 70 hertz, go 2 display properties, then the settings tab, then advanced,then monitor. and set it as i said. turn off computer after you change settings. hook up the nec, you then should be good 2 go. good luck! and please rate this solution. if you need further help, reply.

What OS are you running is it Windows XP if so press f8 to get into safe mode if this happens its a software problem if nothing goes again then the problem must be the motherboard??????

Is it actually going to sleep or is it just really dim in the background? I'm currently investigating one I've been given to fix, and have ordered a new inverter board to try and fix the problem.

Hi Jeryl; Im sorry to have to te3ll you but when the power went out it sent a surge to the external monitor . This blew the monitor which in turn blew your video display. This is a not so uncommon problem with laptop displays. They are very fragile. Especially when it comes to power urges. The only way you can fix this is to replace the monitor. Even this may not fix the problem. It could be any one of a few thousand parts inside your laptop. Best advice would be to let your local repair shop do the repair. Hope this has helped. If it has please accept this answer. Thank you; HELP2DIY
