Picked this up to fix today.....
When the unit was switched on for a 10 minutes of so it would then turn off and if you tried to turn it back on again it would only stay on for 0 - 2 seconds after that.
After cracking it open I tried a working CCFL in each of the monitors CCFL sockets to see if that was the cause. The monitor still switched off after 2 seconds. At first I didn't think that it could be a bad CCFL but after my past experiences with them I wanted to rule them out for sure so I tried 2 working CCFL's and then 2 of the original monitor ones and the back light came on and stayed on!
I tested both of the faulty ones individually one of them didn't work at all and the other one did work but I could hear a slight hissing noise from it that could not be heard from the others.
After taking the panel apart the 2 low voltage cable practically fell off the end of the tube so I re-soldered them on and the monitor is now up and running again! its been going for an hour strong so far.
Hopefully this post will help others to make sure that when you are testing things out you need to check and then double check. Otherwise it might cost you extra hours of your time and you may potentially start buying components that are not needed.
Something I learnt from re-soldering the cable to the CCFL was that if you very carefully cut off the shrink wrap holding the cables together then you can pull through a little extra cable to make the soldering easier and then pull the remaining cables back through the end to make sure that the cable is nice and tight.
Attached is a pic of the monitor running and a slight shot of a multimeter as we know how much retiredcaps likes them
