Re: STAPLES SP9106 -Strange behaviour.

I have one of these monitors too, and it comes on at first, but after about one minute it starts to flicker, then it shuts off. I do not have the original power supply, but I'm using a PC power supply with more than enough power on its 12V supply. The three CapXon capacitors looked fine, but I replaced them anyway. No improvement. I also re-soldered many joints on the LCD driver board. No improvement.

Re: Dell E153FPB Back Light problem - and another

[B]Just wanted to report back and say that the Dell E153FPb that I repaired back in August is still going strong. [/B]

I've been so encouraged with the success that I purchased a broken LCD monitor on Craigslist for $10 and attempted to repair it for use on another PC of mine.

It's a [B]KDS "Radius"[/B] LCD monitor with exactly the same symptoms that the Dell had.

I poked around with it for a while, looking for a blown fuse or bad caps. I re-soldered a few, but nothing helped....

Re: Dell E153FPB Back Light problem

[B]Ahhh - finally I've found the problem!!!![/B]

After a lot of trial and error I have the CCFL lamps back on!

I won't keep you in suspense any longer... The problem was a [U]blown fuse![/U]

No... not the big white one, it was a little black one labeled [B]PF751[/B] (see previously posted photo if you're interested - it's on the right side and looks more like a rectifier diode).

I can read the letters "MS 2A" on it - so I guess that means that it's a 2 amp fuse. Someone else...

Re: Dell E153FPB Back Light problem

I inherited a defective Dell E153FPb. It has a defective backlighting.
I tested the bulbs in another LCD, and they are good, so it must be
a problem with the inverter. I've been reading another thread on this
site about the Dell E172fpb.

Both have Benq inverter boards and both are plagued with
similar backlight failures.

The partnumbers for the transistors are slightly different.
The C5706 are used...
