Westinghouse L1975NW 19" Widescreen LCD
Power Supply: DAC-19M005 (DAC-19M009 Later Generation)
I get video, but still after replacing two blown caps, no backlight. Then I replaced the mosfets, no backlight.
As far as I can tell I'm getting no voltage to the inverter, no spike at startup, nothing. Using a craftsman digital multimeter to do the checks.
Another member, eguevarae, mentioned SMD fuses. I'm not familiar with all the different types, but I don't see any on the board that would suggest being bad.
Any specific things I should test? Also how exactly to test too?
I've attached two extremely large shots of the top half and bottom half of the board. Please photoshop any test procedures or components to check You can save the images and zoom around and see far better than with the naked eye!
