It uses a 2SC5707 transistor for the inverter
Its specs are 80V, 8A, 15W
Has anyone used a substitute that they could suggest
I can get them from WES for cheap
just curious thats all
cheers
The lost forum had a great thread about these monitors
and the replacement transistor. Does any one of hand remember
the equivalent of those transistors or the part number
cheers
When you do things right, people won't be sure that you have done anything at all

I got one I'm trying to fix... I'll take a look at it at lunch...
Hi Best4less
Have heard of MJE340 or MJE13003 & 2SC5706 or 2SC5707 being used.Specs for SRF9224
cheers

Your best to get the actual transistor from WES. The replacements I found just didn't cut it.
What would you do if your server was stolen or failed beyond repair?

i was lucky enough to solder up all the pcb and my monitor is all good for now, it was a fp767
however in my travels i found this
I changed the 5707’s on my BenQ 767-12 but the originals checked out ok and no change. I then jumped the fuse PF751 (looks like a diode) with an automotive blade fuse and resoldered the transformers and hot section and voila!
Trannies from Farnell. Ordered them at 4pm and they were here at 0730 next morning
Just found a Dell 172FPb in garbage room, with flashing power LED and black screen.
Tried re soldering main transformer = no joy
Tested 2SC5707 transistors, found one shorted, replaced = steady power LED and image visible in strong light but no back light
Resoldered all transformers = much joy
I think the forums are correct in that the transformers appear to fail, but what is actually happening is guys are replacing them unnecessarily. If they just resolder the old transformers that should do the trick.

Hi B4L .I got the right ones from Farnell.
There are two there that look the same but are mosfet switching transistors and they fail too
