I have this tv but the white of the ice (watching hockey) is yellow and I can't seem to get the color adjusted right. The user guide I found online only has instructions to go through, which I did, but still the white isn't white and movies that are dark on a regular tv are black and I cant distinguish anthing in the picture. Is it just going bad and won't be able to adjust the color?
If you turn color off and stand back and examine the screen---if it is not black and white but yellow looking you have bad Glycol in the blue picture tube which is quite common.
Easy way to know for sure is with set on and rear cover removed peek with a small mirror at the three lens---don't touch anything with the set on===each tube red,blue, green should have a picture with the set on.
Likely you will find the blue one looks like a floodlight with little or NO image/picture.

What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps

The problem is an aging tv. The small signalboard needs reworked. Send it to PTS elctronics for repair. It will be guaranteed work. Tell your local tech.
