The screen on my Sanyo suddenly went "grey" one day. Now I can turn the tv on and for several second the tv looks fine before going "grey" again. Sound works fine. The grey screen also is whitish in color and sometime has a darker grey circle in the middle...weird huh? Any help would be great. Thanks Ken
Dont know for sure but i think that the tube is going bad. Have one in my shop doing almost the same thing.Taped on the tube and it does strange things. My tube tester wont test this kind of tube that is in these sets.Not much help but it is a start.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
hi do you mean the colour flashing on the screen, if so it's gone in to screen burn mode try press menu on the remote, retune the tv, if this don't work get back to me with model number of the tv help you a bit more thanks
It's possible that the screen itself went defective or the controller board for the screen. It's best to use the warranty at this point because the replacement board or screen panel maybe somewhat expensive. Being that it's only 8 month old, manufacture warranty shouldn't be an issue.
I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.
