I have 6 of these monitors and they all have the same problem. They all have over 2000 backlight hours on them based on the on screen menu timer.
When the screen goes black, the power light stays green and I am able to see faint image on screen by shining it with a flash light.
I have disabled the on screen sleep mode and power saving mode via screen menu.
I believe I have isolated the problem to the inverter on all of them. Since the PSU and inverter are on the same board do you think recapping the board will help? All the caps look good. I dont have an ESR meter.
I have checked the backlights by using my CCFL tester made from a Case mod kit and the lamps stay lit (only able to check one at a time)
I plug the TEST CCFL from the mod kit into the inverter board and the light only lights half way up on two adapters and then goes out, on the other it lights up completely, but goes out in seconds.
I have googled and searched the heck out of this problem and have not found much. I do see the board is used on lots of other PSU as well, but in different configurations.
Any ideas on this problem?
