I guess no one has ever seen this problem before?

Re: Dell E153FPB Back Light problem

I figured someone here has had to run into the same Power inverter board with the same problem before. I was just wondering what other people have tried so I get an idea of which ones to test. It would give me the ability to do it on my lunch hour at work where I have all the proper equipment to remove and test them. As at home I do not. I cant do them on company time thats all..

Just trying to narrow my search down.

Thanks.

Re: Dell E153FPB Back Light problem

I know I could just go buy the Power/Inverter board but I dont want to spend that money on that. I could buy a new monitor for that price. I know the Benq DS-1107A is the board I need to look at but I have not Idea what Transistors to look at to replace.

Any Help would be greatful!

Thanks

Well I have 3 Dell E153FPB LCD's that have a back light Issue. I have tried to do some research on the Transistor problem for this specific monitor but havent really come to any real good conclusion or even the specific transistors to test. I am not afraid of doing board level work at all. Thats what I do for a living but this problem stumps me a little bit.

I took one board and reflowed everything on the board. It seemed to work for about 2 hours then dropped out again.

Any one got any good suggestion on this Dell aka Benq monitor?
Thanks
