Sony KF50WE610 Vertical Blue Lines Across Screen

I have a sony rear projection LCD TV that recently started having multiple vertical blue lines across the screen. When the TV is first powered on, the picture is fine, but usually within a minute the blue lines appear. When powering off, the lines remain during the time it takes the TV to completely power off (between no picture to black screen). If powered back on right away, the blue lines will remain; however, if left off for a while, picture will be fine at initial start up for about a minute.

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!

I installed new electronic ballast in some florescent lights located in a room directly beneath the television. Apparently something in the ballast caused the vertical lines, even when the lights weren't turned on!

Blue Vertical Lines on the screen


It means the optical block is going bad. Contact Sony support. They will sometimes warranty these even after the 1yr warrany has expired. Have your model and serial numbers handy.

Vertical lines


IF the area of the OSD (on screen display) displays the same vertical blue lines as the rest of the screen, then it is most likely the optical block assembly at fault. It's part number is A1606006A and should cost close to $2,000. I'm assuming the set is out of warranty. I know many people are hooked on Sonys, but as a technican that works on them, I wouldn't want one in my home.
