This symptom comes after convergence output ICs failure in rear projection tv. Replacement of convergence output ICs (usually two ICs) will fix the picture problem.
Let me know if you are handy with electronics stuff repair, can remove and install parts in circuit board with proper tools and wish to replace defective ICs in tv to provide you more technical info.
And if you are not comfortable working in tv circuit boards then local tv repair shop will help you because it requires expertise.
Thanks.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.
