Faint No Image / Backlight Out on Monitor Westinghouse L2046NV

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

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series

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! :)

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

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 [email protected], 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.

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.

try to power cycle it to reset it

"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.

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

well i just had this problem this morning i woke up turned on the monitor and it came on but went out. but i soon found out it was not the display that is not coming on its the black light. if you look closely you can see the display but there is no light to light it up so you can see. it doesent seem to be anything wrong with the circuit board just the black light i am going to be taking the monitor apart to see if there is anything me or any of you can do for the monitor to fix it.
