Question about Westinghouse L1975NW Monitor

1 Answer

I have a Westinghouse L2046NV lcd monitor. It was working earlier. I moved my computer, unhooking and rehooking the connections. Now when I boot the pc I do get the windows 98 curtain and it shows up clear, but when the desktop is just about to show the screen goes "near" blank. I say near because I can faintly see the image of the desktop. I tried going from the digital connector to the analog connector. If I turn the monitor off and on the desktop will show clear for a second and then dims again.

You have a monitor with a very common problem, a blown power supply. The heat that builds up in the monitor case causes parts called capacitors to overheat and blow out. When you turn on the monitor they try to hold a charge and show a picture but loose the charge fast and the picture goes dark. If you can solder then you should be able to do the repair yourself. Go to our web site at: and look at the pictures of what the blown capacitors look like. Now open the bad of your monitor and replace any that look like the pictures. The values that you need to purchase will be marked on the sides of the blown ones but will be values like 220uf, 470uf, 1000uf and then a voltage rating. Be sure to get high temp (105c) replacements or you will have to do the repair again in a month or two. The parts at Radio Shack will not do there are several places on the internet to order them from or we can supply you with them. When you install the new ones just insert the caps with the polarity stripe going the same direction as the old ones come out. If you have any questions just let me know. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping.

I hope this helps, if so please rate our solution.

I have a Westinghouse L2046NV Monitor and it does not come on. The monitor has gotten worse over time. I have removed the power board and found the six capacitors to the right are all bulging and 3 of them...

You may want to get the capacitor kit, but you need to get the board number used in your monitor version.
Eample of the kit:

I will not use RadioShack caps, since they are not low ESR type which is required for switching power supply, they will not last if you use generic electrolytic caps.

You should remove one cap at a time so you can see what the value is for each cap.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

More likely the filter caps failed and may have taken out the inverter fuse and the MOSFET in the inverter circuits also. yoo need to open it up and inspect the inside, see example of failed monitors due to bad caps:
