SOURCE: sony 51inch tv blue screen appears

I had just adjusted the lower right adjustment on the screen focus block. 1. Remove the front speaker panel (there were 2 screws) 2. After the panel is remove, unscrew the sheet of plywood that's held together with 4 screws, this will expose the TV's innards (guns, etc) -- be careful. 3. At the bottom, there's a small box with 6 adjustable (via a philips head screwdriver) screws. Disregard the top row of 3 (they're for focus). 4. What I had to do was adjust the left most one ever so slightly with my philips screw driver. It seems the TV was over-firing blue causing everything to have a very slight blue tint as well as the lines. Once adjusted, the TV was good as new.

SOURCE: 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!

This model also has a paper filter for the Optic block that should be changed. No one ever said anything about it. shortens the life of the optic block if not changed.

Sony Trinitron picture turning green hues


Nowadays CRT's do not have good quality shadow masks anymore. After heating up a little they can give a so called "blooming" effect giving a blue an yellow leaf effect large over the screen. Reason nonparallelity in deformation of the shadow mask.

TV turned off itself


Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?
