Replaced one W fuse, now it just cycles through power, on off, on off. You can see the backlight quickly light up then off every time.

Tested the other two fuses, they read just fine. The one W had a varying result.

Re: 19" LCD - No Backlight - Replaced Caps - Replaced MOSFETs

PS. I already plugged in new lamps to the board... no light up. It's not the lamps.

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...
