I am having problems with intermittent green snow that changes with the picture. I still have normal colors, they just have splotches of green snow. It does seem that the frequency is getting much worse.
The set is just over 3 yrs of age and had been doing this on an off for more than 1.5 yrs. Before it was always infrequent and would go away quickly.
It is there on all inputs and sources. I have pics if it would help.

Re: Problems with intermittent green snow
Looks like green horizontal lines, this is definately some type of filter problem. Looks like in the HV or Horizontal are. It first looks like turner problems but you say it's on all inputs. Then if that's correct it's not the tuner.

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
I have the same green dots that are seen especially when the bacground picture is dark or black. Mine does not seem to be changing when it warms up, and I also get it on my digital cable as well as on any DVD's I play. Please help with any advise. I think it was always there, but I assumed that a dgital cable upgrade would fix it - I should have known better...
Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck

It is a 20" TV set and will most likly, im afraid to tell you, cost more to fix then it is worth. The problem is a bad Picture tube, an intermittant CRT socket or the video jungle IC is intermittant. If you want to invest in an estimate, check out first if it will go towards the repair, as then maybe you can get it fixed at a good price, as long as the picture tube is not the problem Good Luck
