If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
hi" do you try to adjust color settings.theres a red,blue,green color adjustment under picture setting.
try to set red color to full. of you already do that. probably your display driver board has a causes the problem. display driver board produce image comes from the tuner, then it sent to x and y drive of your LCD screen.
There is quite a lot you can do. Go to menu, picture settings and select user 1. From here you can adjust everything from colour to contrast to warmth to sharpness. The best thing to do is to switch to XD manual adjustment and make sure the mpeg noise reduction is set to max. This removes artifacts and gives a better picture. Oddly, connecting via SCART rather than HDMI will give a more watchable picture if the HD broadcast is't at a very high bit-rate.
Go to your TV settings and change the "Zoom" function (not sure if LG has same terminology as my Sony) - you can flip through different options until you get to the setup that does not "stretch" the picture to fit the screen - if certain shows are filmed in 4:3 format (or square), they will need to be displayed with two black bars on either side (letterbox) on a widescreen set so the image is not distorted or stretched.
Adjust backlight respectively asin the brighter the room the higher the backlight setting the darker the room the lower if you go below 16(if the room is totally dark, turn backlight to 0 and bump up brightness 3 or 4.
p.s. the cinema setting is pretty darn good for out of box calibrations just turn off high contrast, colors, tru motion for normal non 100% computer generated movies for example, finding nemo and the rest of the animated movies look excellent with tru motion regular film is too video like it looks like soaps to me but hey you may like it so whatever floats ur boat do you have blu ray player, well if ur going to get one get the bdps350 as it does 24fps excellent and well so does your tv it actually uses 5:5 pulldown which is great. (leave tru motion off when feeding 24fps/ real cinema!)Great tv pick dont follow the hype lg is a good brand. lol no i dont work for lg just sick of the sony, samsung, sharp fans. As far as lcd goes lg70 is it right now. I didnt calibrate for sd but i would say they should be pretty close honestly. ill check when i get time.
First try go to TV mode setting, menu, setup, you should get what you wanted to program the colors, If still doesn't work please contact me by calling # 323-767-6030 and I will go through with you.
