Blue spot on screen center. Peoples faces and show blue tint

your color engine is failing its also known as the optic block and they are very expensive to replace good luck google the optic block failure in these sets to better educate yourself with what your dealing with ok it most often blue that shows the failure but green and blue to and red

u just want to take peoples money this site sucks

sounds like the linear adjustment is out of whack.....most projection type tvs, projection, lcd, plasma, have to be correctly aligned so that the color grids overlap each other to properly display the correct hue being created. you'd need the service code to re-adjust it, or have it serviced. also possible that one of the color grids is bad, but if you have all three (red,blue,green) colors showing on the entire screen area i would doubt it

This might sound like a worn spot in the (blue) lens from heat, or a bad color driver on the mother board. It could possibly be dirt or condensation behine the lens(s)

CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.



TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.





Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

The problem is an expensive one. The blue display has become distorted due to excessive heat overtime. The blue display is closest to the lamp and gets most of the heat. The Light Engine must be replaced by a repair shop to correct the problem.

if you have hd cable or satellite box make sure the component cables are properly connected(green red and blue) and matching same color in source (cable box or satellite and tv as well)
also make sure in tv menu that color and tint are 50%

careful adjustment of the y sus pcb using a scope cures it, i repair these all day for lg

Some people have a scale on their T.V. somewhere, or for most cable users it shows on the menu an area where you can change contrast, color, tint, brightness, ect...
