Black shows upas darkred, If image is on screen bright red pixels
When I turn my tv on without an input connected, the screen is a dark red color. As soon as i switch it to any input so that there is an image on the screen, bright red pixels show up. Everything still has a red tint to it though. I have changed all the color options including the color temp with no avail.
Tech support of course will not just tell me what this issue is, instead they will tell me to send it in for diagnostics and charge me a fee for that. Isn't that what we were trying to do on the phone? I thought so but apparently not.
I figured i would take this to the internet and see if i could get some help. I did take the back panel off to check for loose wires, and bulged capacitors but did not see anything like this.
I have only had this television for 13 months. Sadly no extended warranty as i wouldnt have expected to need one.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Cause of screen burn typically is pixels are no longer showing full range of color. Typically a shop would cycle screens or blocks of very bright colors alternating colors to unstick any pixels not showing full range of some color. Setting tv back to factory default then adjusting could help also turning up brightness. Change color settings from cool to warm could help. Could also be a refresh rate. Verify tv is set to display at same rate as input device like cable box set to output 1080i while tv native is 720p. Just because there is a pic doesn't mean they are synced.if tv has to convert signal from 1080i to 540i then resize to fit 720p tv it may slow refresh rate tv is trying to display progressive scan image but not enough data is coming in so it redisplays previous image on every other line.and new data on every other line.
solution is check output video settings of source to match native resolution of tv. Hd cable box this is common as tech sets output to high resolution 1080i most inexpensive tv are 720p
Some newer TVs do not have the traditional "yellow" video input, known as an "AV" connection. Even without that input, you should be able to use the standard three-color Wii AV Cable that came with the system.
What to Do:
Look for "component" inputs on your TV. These connections have a row of five differently-colored inputs (green, blue, and red for video, white and red for audio). If you have more than one set of component inputs, it's the first set that generally works with standard AV cables. Look for a set that has a green input with yellow around it, or the word "video" just above or below it.
Plug the yellow end of the Wii A/V cable into this green "Y" input. Plug the white end into the audio "L" and the red into the audio "R." Leave the blue and second red holes open.
Turn on your Wii console and set your television to the input select being used.
If you are seeing the image from the Wii in black and white, try the following to get the image in color:
Cycle through your television's input channels (usually with the "Input Select" or "Source" button on your TV's remote control) to find the input select that has the image in color.
If you're only finding the image in black and white, you may need to switch the setting of the input select from a component signal to a standard AV signal. This can be done by:
An on screen menu option. This is often accessed by using the "Menu" button on the remote.
A button on the remote that switches between the standard and component signals. These can be labeled such things as "AV" or "Video."
usually you can correct this issue with only a few system checks, dark streaks can be caused by damaged pixels on the screen, in which case you need to replace the TV.
Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.
Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.
Inspect the cable connection. Oftentimes when connecting a computer to an LCD TV, you can have strange dark streaks across the screen. Use a DVI-to-HDMI cable connection when plugging in your computer, then press the "Menu" button on your TV remote, select "Picture" and chose "Square Pixel." See whether the image adjusts and the dark streak goes away.
Contact the manufacturer of your LCD television if the dark streak remains. This streak can be caused by a defect in the television; if the TV is still under warranty, you can have it replaced.
When the TV is on, if you look at the screen and can see dark images, then you will need to replace both the inverters.The inverters drive/power the back light inside the LCD to show the images.You may have to try and different channels and or inputs to truly see if you can see dark images while the TV is on.If you are hearing audio from a channel or an input then you should be able to see the dark images if just the inverters are bad.
If the screen is dead black without any dark images, then typically your LCD screen/module is bad.
If the TV powers up (power supply is good), you have audio and the remote will work with the TV (the main board is good), the only parts left is the inverters or the LCD screen/module.
I can get you LG part numbers if you need them.
Your CRT's getting old. Plus dust on lenses don't help much. You have to open front frill (below screen) and back of the TV. Clean up lenses using dry paper towels, do not wet. In front of the TV after grill remove center cover and locate "black box" that have 6 potentiometers on it that looks like plastic adjustment screws for philips #2 screwdriver slots. 3 of them should read "Focus" These you don't touch. Another 3 reads "Screen". Put some still image on your screen (like paused DVD movie frame). Carefully add brightness in all 3 colors trying to avoid horizontal lines appearance. If lines show up, just turn it back a little. Try to keep color balance looking at the picture. This procedure will brighten up image but further reduce CRT's life.
In case that you posted wrong model here and you have DLP Projection TV - just replace the lamp.
LCD stands for liquid crystal display.These types of displays have been around for awhile and are commonly used with computers.One reason for their big popularity is the ability to produces a better picture than CRT monitors but also being much thinner. Pro’s
Low Energy Consumption – LCD monitors use very low amounts of power. This is why it is very commonly used in battery powered devices.
LCD screens also reduce the amount of glare on the screen which can be very beneficial if your TV is in a room with lots of light.
If an image is left on the screen too long, LCD screens are less likely to experience the image being burned into the screen. If this does occur, it’s easier to repair than other types of TV’s.
The viewing angle of an LCD TV is typically not as great as Plasma but the difference is not great enough to make a huge difference.
LCD TV’s can sometimes get dead pixels which aren’t typically covered under warranty. Although they are very small, they can become very annoying.
Brightness levels aren’t as great as Plasma and it’s not possible to display darks quite as dark.
Plasma technology hasn’t been as widely used as LCD in previous years but has become very popular in large HDTV’s. Although they have historically been more expensive than LCD TV’s, they are becoming more comparable in price. Pro’s
Brightness and color are the major advantages of Plasma TV’s. They produce rich colors along with very deep blacks.
Their wide viewing angles allow more people to be able to watch TV comfortably.
The pixels of Plasma TV’s are lit individually unlike LCD screens. Because of this feature, the pixels can be completely turned off to display truck black colors.
The lifespan of a Plasma TV is typically shorter than other types of TV’s. The lifespan can be extended by turning down the brightness of the screen.
Plasma TV’s are more susceptible to screen burn-in where an image is “burnt” onto the screen when left on the screen too long such as a network logo in the bottom right corner of the screen.
Plasma TV’s require a panel of glass to cover it. This glass can reflect light and make it difficult to see the picture. If placed in a dark room, this typically isn’t an issue.
