Re: blue hue

This might denote a problem with the CRTs (Red and Green). I would suggest having them checked with a CRT analyzer and if they are bad, having the technician perform a picture tube rejuvenation on all three CRTs. Now this will cut the tube life down to about 2 years, but if the CRTs are bad you really don't lose anything by doing this.

I hope this helps
Thank you

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.

The tv comes on and picture is perfect, then blue hue starts and progressively gets worse. Finally all blue with only sound. Turn off and back on and picture is perfect then fading begins again.

During this procedure DO NOT touch anything else than whatever I mention here! You can get serious injury due electric shock!
You have to wait for TV to warm up and get worse blue hue you can get. Than remove front grill and behind it locate center shielding piece that also have to be removed. It held in place by 4-5 screws. Behind that "shield" you can locate "black box" size smaller than pack of cigarettes made out of plastic. It has 6 rotary buttons. 3 of them are" focus " and another 3 in the row are "screen". They all marked - take you time to study them with magnifier glass and flashlight if necessary! Locate one with letter "B" in "Screen" row . Others for green and red. You have to slow and carefully turn it counterclockwise using matching Philips screwdriver until blue is in balance with other colors.
Put everything back and enjoy your TV!

There's a green hue over everything

One of your other color tubes( blue or red ), is blown. The green saturation you are seeing is beacuse you are missing a color to complete the picture. Rear projection t.v.'s are pretty cheap to fix with this problem. Just contact a t.v. repairman.

The color on my mitsubishi model # vs-5041 is faded and foggy.

Hi, did you try a color convergence? I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website: 

Hope this helps :)

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.

Faded colors

If the picture is dark or messed up too bad, the magic focus will not function, are all the primary colors faded? RED GREEN BLUE? You might have a bad CRT, would call a service man to check out.
