This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.

Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.

Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.

The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.

You will have to take the set in to have it serviced.

Sony KF50WE610 Vertical Blue Lines Across Screen


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!

Thin blue line


I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience

2) Later on in the broadcast, it goes away.

One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.

If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
