If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish 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

Large green wavy lines faded in background for 2 months. Then once turn on slowly fades to solid green. Turn off for 10 minutes turn back on, good picture for 3-15 minutes, then fades to solid green....


The Green CRT has shorted and will need replacement. You can verify the problem by removing the Green CRT drive board from the green CRT dont unplug the wires just slide the board off and let it hang suspended then try powering up the set if it stays on without shutting down then you will no its the green CRT for sure. You can get a green CRT from www.tvrepairworld.com

Monitor fades and turns blue


this sounds like a transistor issue concerning the ccfl lamps the power transistors are deteriorating and they will eventually go bad you can have them replaced and that should fix the issue. otherwise I would say have the capacitors that feed the ccfl's may be getting old and need replacement as well, its not something the average customer will want to do but if you have a service center that does electronic repair then that would be bst.
Hope this helps

Picture fade to blue


You can reduce the g2 for the blue tube
open the front grill and open the 4 screws hold the resister block
to have acess to the register block.
Then there should be the black box have 6 knobs
the one call for Blue g2 not the focus block.
Adjust it counterclockwise a little bit
and try turn on TV again

Picture comes on then fades to blue


Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.

Sony KP-51WS500 fades into a blue screen


You have a bad Blue picture tube. with Sony, they suggest you replace all 3 tubes at the same time. If you have warranty coverage good, if not forget about it. Get yourself another TV.
