I have a dell E196FPf / E197FPf 19'' LCD monitor which recently died. I have extensive pc build/repair experience, but I have never worked on an LCD before. After spending some time on this, and other, forums I've come to believe it is the CCFL lamps that are the problem.
When the monitor first went on the fritz, it would light up for a second and then go dark, if I gave it a couple of whacks (I know, that's terrible) it would come on and then stay lit up perfectly fine until I turned the monitor off again.
After a couple of weeks of smacking it every day, that finally stopped working.
I've disassembled the monitor and visually inspected the components (I do not have a multimeter to do a proper check). None of the capacitors are bulged, and there is no visual evidence of any problems with the power/logic, or inverter boards.
The only thing I can visually see that looks bad is on the ends of all of the lamps, they appear to be blackened, and possibly burned out. Combined with what I've researched so far, and the symptoms the monitor showed, I've come to believe the CCFLs are the problem.
Now however, I'm having a very difficult time locating the proper replacement bulbs. I also am uncertain whether I should be purchasing just the new bulbs, or new wiring harnesses as well.
Any help is appreciated, either locating the proper replacements, or if anyone has any other ideas please feel free to share.
