Re: Fix for Benq FP737s 17" (Q7T3)
Hey guys.
Got all my monitors working except one, which virtually burst into flames.
The good news is that the LCD and the little VGA board still work.
Has anyone else tried to manually power this up? I intend to use the screen as a light weight portable screen backlit by LEDs and powered by batteries (if possible)
Could someone try this and if it works, could they do a diagram of the VGA board and point out which pins require what voltages, etc?
On the schematic, it...

Had no luck so far with replacing the fuse, FU9024N and 5705 , and I still haven't received those other 5705s I originally ordered.
Do you know what voltage the backlights take? I might try to power it externally as an alternative solution.
The bright side is that I can use these to make a multitouch screen.Leave a comment:

Thanks. That actually worked out cheaper than some I bought from another ebay seller (that haven't arrived still)...Leave a comment:

Oh, and I can't find a supplier for IRFU9024N in the UK. Any suggestions?Leave a comment:

Another one bit the dust today at work, so I'll have to give this a shot using parts from the failed one. The parts still work, my guess is the fault it elsewhere.Leave a comment:

I've got the one to work (oddly) and the other doesn't.
The odd working one has backlight lit up even when the power is off, which means I have to leave it on to turn the backlight off.
The other doesn't light up at all.
I'm not willing to spend any more money on these than I already have, so I might make a projector out of the one that doesn't turn on.
Having said that, the smaller PCB with the VGA connection connects to the power PCB. Could you get the pin out for that for me?Leave a comment:

I replaced the 3a fuse, and it instantly blew up along with the SC5707's.
Smoke was pouring out of it and it stank the house out.
my guess is that I've blown a bit more than the SC5707, but there are burn marks only around the SC5707s.
I've ordered replacements they should turn up in a few days. Anything else need replacing besides SC5707 and the fuse?Leave a comment:

Re: Fix for Benq FP737s 17" (Q7T3)
Greetings from the UK.
Our work office is loaded full of these benq monitors (all Q7T3). Needless to say they'll all eventually fall to this problem as we've had 2 die already out of 14 identical models.
Anywho, I was wondering if anyone could clarify exactly what I should replace in order to get it working (identifier code on board, and part name / code) and any basic and simple preventative measures I could take to stop it happening in the future, if not stop it happening quickly again in the future.
