Firstly - brilliant site and forums, I've lost hours over the last week looking through it
I arrived here while looking for a fix for the above monitor. I've got a pair of them that I bought about 4 years ago as I like a big desktop
Originally I thought the back-light had gone but once I dismantled it I realised there were 2 lights and they're a pig to get out so I investigated further. I did a bit of juggling of parts with its working twin and proved that the back-lights were OK. Googling led me to the Dell E172 and common 4 transistor problem but I also came across this:-

As the cap in that area is bulging and the board scorched where the transistor is I'll try that fix first.
FYI the board is labelled 48.L0Y02.A02, the bulging cap is at C712 (Jamicon 1000uF 10V 105C 440C2(M) ) and the transistor is at IC701 (can't make out what it is but I'll go with the one in the above link).
In Photo176a I think I'll add some extra holes in the marked area to help the convection airflow seeing as a lot of the problems seem to have an over-heating aspect.
