**Copied from another product however my problem is the
same. No picture what so ever. even when shining a light into the screen. would
this be an inverter issue? **
Hi, Whenever I turn on my monitor it displays the computers
output briefly (~half a second) before going blank. I have tried the monitor on
two other computers with the same result so it is definetaly not a computer
problem. The power light on the front of the monitor stays green when the
screen goes blank. Whenever I turn the power off and back on again the exact
same thing happens.
Help please!
**PLEASE NOTE - This solution applies to ALL LCD's
but NOT CRT's**
It's a very common problem with all LCD monitors
LCD's use four small Cold Compact Fluorescent bulbs to back light the display.
(thats what gives the LCD it's brightness allowing you to see it)
The inverter board runs these lights and when they go bad they will typically show
symptoms like you have or the monitor power light comes on and you have either
no display or a very dim display.
If you ever have one that has no display but the power light is on you can
check by shining a flashlight directly into the LCD from the front (right into
the screen) if you can see an image then it's either the inverter board (most
likely) or the CCFL bulbs have gone bad.
IF there is no display even with a flashlight, the P/S board is malfunctioning. Bad capacitors or LCD driver board circuit. Mine did this and it was bad caps, 4 of 8 were bad and a burned out chip on the P/S board.

Hi. Does the TV stay on I.e standby light stays on OK.
if so try shining a torch into the screen while the TVs on see if you see any picture .if so possibly backlight issue.
. What's your make and model number
Hi. It could be one of a few parts
I.e main board you say the TV stays on I.e standby light stays on OK.
if so try shining a torch into the screen while the TVs on see if you see any pictureor menu when pressed on remote .if so possibly backlight issue.
try darken thye room your in when shining a torch at the screen
. What's your make and model number
as it could be tcon or main board issue even
This could be caused by multiple things. The first problem that comes to mind is a bad power supply in my experience. The second problem that comes to mind is possibly a bad t-con or backlight inverter board. Could you tell me, when the TV powers back off can you see a picture in on the screen if you shine a flashlight up to the display?
hi in a dark room shine a flashlight on the screen see if you see an image, if you can then you may inverter/ power board problem, if you can't you may have mainboard or tcon board problem thanks
It sounds to me like you either have a bad inverter board(The board that lights up the screen),or a bad bulb in the screen itself.When you turn it on,and the screen goes away,shine a light on the screen,and see if you can see a picture.I hope this helps.Thank You very much!

amy .... first you need to get the data cable for that phone so that you can hook it up to your computer. second there is an lg program that will allow you to download your contacts etc to your computer. you may already have both of them. if not go to http://www.lge.com/ca_en/support/product/support-product.jsp and locate your phone, it should give you the information about the data cable if you don't already have it.
From what you say there is probably not much you can do with it, the parts inside are SMD, to small to work on. If you could still see txt on the screen when you shine your torch, it could be fixed by replacing the back lighting PCB.
Take a strong flashlight when the set is on and shine the light into the screen see is you have a picture as it may be the backlight. If the screen lights with no picture its a pcb board problem. Please verify your model number and I will try and assist you.
