It sounds that the back-light section has some fault with your TV. Otherwise, 30% brightness, 60 to 65% contrast, and 20 to 30% color settings should give you perfect picture.

it gradually get damaged pls it shut off for sometime.

Sounds like the sensor ribbon has slightly come out of it's socket.

Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:

• Cool: Gives the picture a cooler, slightly bluish appearance.
• Neutral: Gives the picture a neutral, more natural look and appearance.
• Warm: Gives the picture a warmer, slightly reddish appearance.

If your TV has a Hue setting, follow the appropriate step below to make adjustments:

1. Move the setting to the right to reduce the reddish appearance.
2. Move the setting to the left to reduce the greenish appearance.

Check in your printer driver settings "advanced" section, and see what the presets are. if the RGB or CYMK settings have a slider, see if the magenta is set at 100%. If it has a slider, try it at 90%, 80%, etc until you have a less pinkish hue. You can then create a printer profile which will work with the photo paper you are using.

Different photo papers can cause hues like this.
Also, you can remove pink any unpleasant hues with most photo image editors through color correction.

It's possible that you have a contaminated cartridge...especially if it's a refilled tri-color cartridge.

The light engine will need to be replaced. Without a warranty the part is very costly. You are lucky...

My computer did this and I think my TVs just gone the same way. Was definitely a loose connection somewhere. In the computer monitor it was because the pins in the plug were slightly bent and if I moved the wire the picture got better. In the end I had to replace the connecting cable
