My screen symtoms are a little different on my L1975NW.


I am guessing the LED power indicator blinks green then becomes steady when the screen "turns on" (shows video). The problem is most likely a failing backlight power supply. That's why there is a 30 minute delay. Try to disable sleep mode and see whether that helps.

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.

I have the Westinghouse L1975NW


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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.

Notes: When the caps went out, it may have raken out the fuse and the MOSFET in the inverter circuits with it also. http://www.instructables.com/id/How-to-repair-a-Westinghouse-L1975NW-19quot-LCD-/

L1975NW Monitor: My monitor is very dark; too dark to even see how ...


More likely the backlight is not on, check the caps (leaking/bulging tops) in the power supply first, then check the fuse in the inverter circuits, when the caps went out it may have taken out the MOSFET for the inverter transformer with it. See failed WESTINGHOUSE and other monitors due to bad caps.

The color is incorrect on my L1975NW (Westinghouse) widescreen


Try hooking it up to other PC to see if it does the same thing.
Try another VGA cable.
If none of above change the symptom then open it up and inspect the caps in the power supply, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

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.
