    I have a horizontal blue line that goes all the way across the middle of the screen on my 2 month old Sony 46 inch lcd panel hdtv that I got as a gift. No warranty info came with it, so I would like to know if it is an easy fix.

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.

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!

I got this TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Hello im having problems with my sony wega


It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer
