Viewsonic vx924 LCD burnt transformer - T1

My friend had a VX924 that was turn off after it was turned on. The output was just fine, but would go away for some reason. You could turn off the monitor and turn it back on and you could see output for about .5 sec. I did notice that after booting up you could see the desktop very very faintly. I decided to take a look at the power board so I opened up and found that T1, which is some 10 pin through hole part with EPC 19 on it, has been burnt up on some of the coils. I guess it's the CCFL transformers...Does anyone know where I can find a replacement part for this transformer. I can't find a schematic, layout, anything for this board. Anyone know where I can find a data sheet for this transformer, or the part number, or any information on the details.


I think viewsonic used the same or very similar power board for the VX710, 910, 912, and 922.

Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

ViewSonic VX924 transistor

Hey Brandon.
Besides those transistors, you may also fine the large capacitor adjacent to the transformer gone too, Possibly the transformer may be bad too ?
Also the 924s used at least two style boards.
