Hello, my monitor is not showing any image on the secreen the light is turned on but the monitor does not seem to get the image from the computer, i can tell the monitor has received a signal because the light turns from orange to yellow as if would have been shaken hands with the computer. Is there a reset combination of keys or how can i fix the problem I dont have any warranty left. Thanks EEGordon's post looks legit I opened it up and and two of the caps pointed out are definitely busted. I ordered all the parts and ill be installing them next week. Ill repost and let you know how it goes. -TJ

Open up the unit. You should replace the damaged/bulged caps on it. You should also check the two MOSFETs before the transformers on the inverter section. If that does not do it, there's one SMD fuse beneath the card that normally blows when the MOSFETS fail. You should either replace it r bridge it with solder.

Hello there! when I turn the monitor on it shows the the screen and the image on for about 3 seconds and then it goes back to the sleep mode and it doesn't turn back on what can I do to solve this issue


Bad news, when the DC filter caps went out it could damage a lot of components (fuse, MOSFET's, resistors) in the inverter circuits.

Monitor will not turn on? westinghouse model L2046NV black screen will not turn on what should I do?


Do you see an orange light on the monitor anywhere? Usually the light turns green when the monitor comes on, but its orange when in "standby" mode. If your monitor is plugged in and you get an orange light, that usually means that your video card has gone out on your computer. When your video card goes out, the monitor doesn't receive a signal from your computer, so it doesn't know it is suppose to turn on. So if this is the case, you need to replace the video card on your computer


If your monitor doesn't turn on whatsoever, and everything is plugged in correctly, then you need to get a new monitor or send this one back to the manufacturer for a defective replacement.

Hope this helps! :)

Westinghouse 22 lcd monitor. faint click and went


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: http://s807.photobucket.com/home/budm/allalbums

How do I reset my Westinghouse L2046NV monitor -- this monitor will turn on and light up and the picture will come on but then go off after 1 or 2 seconds -- any ideas ?


Hello, reseting your monitor will not solve the problem, what you need to do is replace the inverter board, if you would like to know price and availability for this model please send a request to parts@wde.com, they will let you know if they have the board, how mutch it is, and they will also troubleshoot with you over the phone at no charge to make sure that is what you need.

Black screen after a brief windows loggin screen


Hello

It's either the backlight, the inverter or the power supply. My shop would charge $50.00 + parts + shipping. I've repaired alot of Westinghouse monitors and I haven't junked one yet.

Monitor comes on, I can see everything perfect then goes black


"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

The screen went blank while the computer was on, we restarted it, the screen shows the Dell sign & the white bar then it goes blank, it won't go into safe mode, the light is green on the monitor, what...


If there is a faint image in the background it is the coils on the planar if no image it is either the invertor or the backlight
If you have a faint image resolder the coils or replace them
