I've got one of these that comes on and then the display fades out to black after about 20-30 seconds. Turn off then on and same thing. When opened up, I can see the CCFLs are brightly lit although the display has faded to black. I replaced the power supply caps even though they were not bulging so I don't have to deal with it later on. I swapped in a converter board (the one with video inputs) and no joy. I opened up the column driver board and blasted it with cold spray. I blasted all boards with cold spray to see if the fade rate changed..... still no joy. I've googled and bad caps seems to be the prevalent problem, I am not using the DVI connector as I know there is a data rate problem with the display blanking out..... Any clues or ideas for whatever it is that I missed??
Thanks a bunch ;)
