The tv Tuner signal board is the problems that causes this whiteout.Its the board,that take in the incoming broadcasting cable signal (plugged into it)
I would suspect either the main board or the t-con board, with the main being the most likely cause. Without an oscilloscope its going to be hard to isolate between the two. Most commonly its the main pcb. The main will have the tuner mounted to it where the rf cable is connected.

Tips for Picking Paint Colors: If you don’t think you’re a very creative person...

    Tips for Picking Paint Colors:


      If you don’t think you’re a very creative person but want to paint your house or even just a room, you might be feeling overwhelmed by the challenge of picking a color! Don’t panic – here are some top tips for helping you choose a great color scheme for your painting project.


      1.Use the color wheel. Don’t be afraid to take a look at the color wheel – it’s not just for decorators to show off to their customers with. You can ask someone in a paint shop to explain to you how primary, secondary and tertiary colors work together (or sometimes against each other).


      2.Try and decide what kind of ‘energy’ and brightness you want in the area you are painting. Is it a lounge that you want to be cosy? Or a bedroom that’s modern and bright? It really helps to visualize the end result.


      3.Are you hoping to your space look bigger or a large room cozier? If so, you can use color to help you. Small spaces will benefit from pale, cool colors and larger areas can be made to feel more intimate with warm, darker colors.


      4.Watch out for lighting issues. Natural daylight shows the color in its truest way whereas fluorescent lights cast more of a blue tone over the overall color. So make sure you pay attention to the lighting issues around the area you are painting.


      5.If you want to play it safe you can always go for neutral colors. These are colors that don’t stand out but you can use furniture and decorations to really add the splashes of color while keeping the walls in more subtle neutrals.


      Have fun! You can always paint really small areas to see how it looks on the wall. And try to be bold – you’ll probably be surprised with how good it looks.

Rainbow static on Plasma Tv
The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.

Blothes of color in center and right side of screen. Very noticable when it's a light background.
May have burned CRT(s), (if you are not talking about convergence.) Burned CRT shows when that CRT (R,G,orB), does not show in an area of the screen where it should. Check bright white color = full R, G, and B CRT brightness. Gray = mid RGB brightness. Yellow = R+G(no B), Blue-green = B+G, no R, etc.

The t.v. has too much color
First set the color to 0, the TV should be in black and white. if there is a purple or rainbow color then your tube may be failing. Most default settings are when everything is half way(centered). If this dosen't correct the issue than there is an issue on your main board.

Probable causes 1) Magnetic field disturbance from near by equipments. eg. Audio Speakers. 2) It might also caused by shifting TV position 3) the degaussing might be faulty. Demagnetizing the set will resolve the problem.
