Re: yellowish tint on all channels

Hi, bad news guys, from your brief description you have a bad light engine, you both need to have a tech verify this but thats most likely what is causing your symptom. This is NOT a layperson repair, you`ll need a tech, BMW Rider

How do I get rid of the pink tint on my tv screen

If it is a rear projection TV then I would look to the IC's that control the Red or Hue in the color circuits. Depending on the year, make and model some have some adjustments. If it is a rear projection
unplug it for a night and day and get back there to each one of the picture tubes and feel around and you will a soft thing sort of like the primer on a weed eater. Press and release it several times. This agitates the electrolyte behind the tubes and could possibly cause a color problem. If you have a newer model of the flat type then I don't really know, possibly the main board. I honestly have never ran into screen off color in the newer flat TV's. Sorry I can't be of more help. If it is a pretty new TV I would call the mfg and ask for one of their techs. He is suppose to help even if it is out of warranty.

LG LCD TV has yellowish center tint

A firm ware upgrade might solve this problem. Upgrading your RAM, if not, the procesor ic on the main board.

We have a new bulb for our 50v720 and now there is a yellow tint!

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, yellowish tint,pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

How do I find out which lamp is blown? My screen has a lot of yellow throughout it. It is a Sony KDF-E50A10.

It is dlp tv that has one lamp as back light source. Yellowish tint is problem of Optical Block Unit (commonly known as light engine) that will be replaced to fix it.
Local tech will help you in optical block unit replacement because it is purely job of qualified tech.

All my channels have a green tint on them.

You have not provided any details about your system. What components are in your system? How they are connected? Etc.
Have you tried resetting the TV? Have you tried switching inputs around?

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
