No picture My tv worked fine one day and then slowly started to get a thin blue line through the center on occasion. Recently, the thin blue line is the only thing on the screen. No picture whatsoever.

Your email addy was not included , here is mine email me I will answer with a solution.TY.

This is vertical problem. The tv have a cold solder in vertical ic or ic is bad.

that could be a sign of a bad panel. my experience is that these panels are more expensive than the tv itself, but might be worth looking into since I've heard about prices coming down

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

call the repair guy, he will be able to diagnose, prbably a bord problem.

THI IS THE INTERNAL CIRCUTRY FAULT BEST YOU
call the service person and dont try to open it other than in side of TV SET HAVING Hazard of electrical shock be handle most care fully .
and check video board and all.

To me, sounds like a picture tube issue. horizontal / vertical controls don't fix it. then its dead.

intermintence in vertical IC deflection its a job for experienced tech need to look for that circuit and do fine job resolding that IC

Hi there,it looks as if you have a frame collaps,this is the first time i have ever heard of this on an LCD tv,i take it that there is no picture at all only a thin line.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
