FWIW: I tried the search function a couple of times, it just takes me to a weird useless screen. Have a large flat screen TV. A couple of months ago a vertical black bar appeared on the left side. Over time it progressed from left to right until now there's no picture at all. Sound still works. Are these things fixable or just throw away? Any suggestions on the subject are appreciated. I'm not a total newby to electrical stuff, got a degree back when vacuum tubes ruled and flat screen tvs were just in the movie 2001. Thanks in advance.
