Blue Hue Replaced the lamp in this tv, (fourth time in five years) and there is still the blue hue to the picture that prompted me to replace the lamp in the first place. Any thoughts? Mechanically inclined, but is this job for a pro?

My Mitsubishi wd-62531 has a yellow hue over half of the screen. What do i need to do to fix it?

Not a cleaning issue.

The lamp shines into a OPTICAL LIGHT ENGINE, which has a series of lens and baffles---blue is the first part of the engine to get that light and heat---in your case the blue area is damaged from the heat----minus blue equals yellow.

The entire engine would have to be replaced--not a cheap part--Google the model number with "light engine" to get an idea of cost.

May be time to either use it as is or ?

Problem with sony 60" rear projection TV

I'm afraid, it is problem of optical block unit (light engine) that produce picture by 3 lcds inbuilt, the blue lcd and its related uv filters become defective and causing this kind of blue hue on screen.
Complete optical unit block (light engine) will be replaced by qualified tech to get tv fixed, light engine is costly part so ask an estimate before sending tv in.

Sony KP-53HS30 Projection TV has pink and blue hue w/timer blink

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.

3LCD Projection TV 2.5 years old displaying blue hue/blobs

I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.
