Re: Benq FP951 Invert/CCFL
Inverter is working correctly.
I have removed the 2 sets of CCFL's and both look fine, no obvious defects.
Were is the best place to buy replacements?
I'm in Australia, in saying that I'm not fussed if they have to be shipped over just dont want to wait months for them to get here....

Re: Benq FP951 Invert/CCFL
Just had a thought, I can get my hands on the same model screen and do some part swapping.
Is there any chance I could damage the other working screen if I put the power/inverter board in it? I don't want to kill the other screenLeave a comment:

Re: Benq FP951 Invert/CCFL
Just tested all 4 transistors and no beeps from any of them.
So next on the list, work out what/how to use a case mod kit to test CCFL's
Thanks for your help Bobdee!...Leave a comment:

Re: Benq FP951 Invert/CCFL
Just checked fuse and both are closed. New and old one.
I tested with DMM in continuity mode and DMM beeped.
So I take it that means it's closed ??Leave a comment:

Re: Benq FP951 Invert/CCFL
Hi Bobdee,
Thanks for your reply, I just replaced all 4, hoping it would fix it.
There are only two inverter transformers on the board and each has 11 points.
To answer your question, no I have not yet I'm just about to start.
This is my first time doing anything like this it's only the second time I have used a soldering iron
.
I'm not 100% on how to check if the fuse is open (I will search around now to find out)
Same answer to "was there...Leave a comment:

Benq FP951 Invert/CCFL
Hi,
After reading through the forum trying to find info on my faulty Benq FP951.
I have tried a couple of things.
My issue is no display, the power light stays on (Green).
If I shine a light at the screen I can make out a very faint image.
I have checked all the invert joins (all 22 of them, hope I'm looking at the right component) and replaced the 4 c5707's and the pico fuse.
Still the same issue, once it displayed an image for about 2 seconds and then back to nothing.
It has 4 individual CCFL tubes,...
No activity results to display
