bsims77010, Tell me brand name of electrolytic filter capacitors on the large "switch-mode-power-supply / CCFL inverter supply" printed circuit board. Are any of them SWOLLEN on the end that is up ??? You can see typical "failed units if you visit YOUTUBE for video clips that show owners/tech's that replace them with new ones and now have working units again. You must tell me more about this "keeps turning off" thing???? Is unit going to "black screen" only?? Or is it going to "black n blank" screen"??? There is a difference!!! If black only then 5vdc might be ok! If "black n blank then +12vdc & +5vdc sources could be in shut down mode. Do you see screen data with aid of bright flashlight held 1 inch from the "black" screen?? Once you have knowledge of what makes "raw white light" on reverse side of your lcd panel, then you will have clue to how the new screw-in, curlie-Q style CFL light bulbs work and what an "electronic ballast" circuit is. 12fixlouie
Post reply if you need further assistance.

You need to verify to find out if it is the monitor is bad or the PC is not sending the video signal to the monitor. Try another monitor with the PC, if you still have the problem then you need to fix the PC, if it works OK then it is the monitor problem.

that means no incoming signal, but some problem i encountered related in vga cable and lost connection on ckt board. as long that the cpu is working and the monitor show (no signal) focus trouble shooting on that parts. replace cable if possible( same port configuration)

1. Take this Monitor and attach it to another working computer to see if it works
2. If it works, it means the video card on your pc needs to be replaced

the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

Check the Inverter card Connector which goes to pannel,Next Panel to AD card signal Cabble,..

Ok shut it off and take the coords out make sure you re-connect the coords back and try it again.. This should fix it! It tooke me 8 times the other day to get a display so i am hoping it works let me know!
