Having problems with your BenQ FP222W LCD Monitor ?

The monitor switches on and shows benq logo, then screen goes black.Tested on 2 computers and still not working. Have changed capacitors on board but still nothing.


Answers :

After changing the caps, do you get steady 12~18vdc feeding the inverter circuits? Inverter fuse OK? It can be bad transformers, or lamps also. Pictures will be great help. See where I post my pictures: http://s807.photobucket.com/home/budm/allalbums
