Westinghouse L1975NW DAC-19M005AF burned resistors

I have a Westinghouse L1975NW 19'' LCD monitor with a Delta Electronics DAC-19M005AF power/inverter board. In the primary power section, resistors r131,r132,r133 and r134 were damaged/burned when a mosfet shorted out. Does anyone know the values of these resistors? Thanks!

Installed new 27-D01567 power supply unit in my 19" monitor L1975nw. have green light but black screen. whats next?


Is the board brand new or used? You will need to verify the voltage (12~18vdc) feeding the inverter circuits, there is also a surface mounted fuse.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Goes dark for 5 to 10 second for no apparent reason?


Look for bad caps in the power supply, it will get worst and can take out the inverter fuse and the MOSFET.
