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!

The blue screen is fairly common and is displayed when inadequate signal is present.
In other words, 'no reception.'

The weak BBC1 signal is kind of a confirmation of your poor signal strength.

Blue horizontal and vertical lines


We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
