your tv needs repair one of the transistors on the neck board is bad..the neck board is connected to the picture tube end inside the tv..but be care full as it stores very high voltage.if you are not a tech have a tech look at it.
Not sure what causes it but it can be fixxed by your local repair guy, I just had mine fixxed for under a hundred bucks, he takes the back off and with a tiny screw driver adjust a few screws to near brand new perfect picture.. and it has been good ever since
could be a jumper on the DMD board that must be removed, look for a small sticker that points to the jumper, or it could be a setting in the factory mode, mute-182-power will get you in there, check the settings for the color wheel
it depends if its just that input or the whole tv itself if it works on other inputs it may not be to bad to fix, but if its the tv itself it depends on how old it is and how much you paid. it could wind up costing quite a bit. so take all those things into consideration. it might just be time to upgrade
It sounds like the common problem with this set. It is an intermittant picture tube, or there is a loose connection on the green drive board on the green picture tube. Try lightly tapping all around on the green drive board while the set is on and see if you have any change. BUT BE VERY CAREFUL! Lots of high voltage on the board. Also use a plastic or wooden device to do the tapping. If you do great, you know you need to resolder the connections on the board or clean the CRT socket on the green drive board. If there is no change, I would bet the green CRT is on its way out. But try tapping the green drive board all over as I said before, that is a very very common fault with these types of TV sets. Good Luck
