The picture color (mostly whites) is beginning to become a dingy yellow in various areas of the screen. Rather than the crisp bright white color when the unit was new. This is also evident in the white grid of the convergence screen.
Is there an adjustment (perhaps in the maintenance mode) that can possibly correct this deteriation of the picture?
THANKS!
I might be that your lens are dirty which just may need to be cleaned or most likely you could have the comtaminated fluid in one or all three of the picture tubes . With th escreen off you can look into the picture tubes and see which ones are affected . Be careful as you can be shocked if you reach around the tubes when the set is on. If the fluid is bad call around to get a good price as it can be changed but some shops will want to replace the tube or tubes that are affected and this can get expensive .
