Hello,
I have had this tv for over 6 years and had from day one.

I have beginning to have an issue that may be simple.

When i first turn it on, after not watching it in a while, it powers right up, sound and video....but i have these 3 or 4 vertical snow bands, each 8-10 inches wide. You can still see the picture and have good sound, and it kind of tries to clear up. I usually turn the tv off, wait a couple seconds, turn it back on and all is fine !!

It only seems to happen when i have not used the set in a couple days. Almost like it warms up...
