Thats a convergence issue which is actually a easy repair on that model. You can get the convergence repair kits from www.tvrepairworld.com which also includes repair instructions.

check your magenta cartridge, and use a genuine toners

This could be from 2 things. 1 is the optical block is going bad or 2 you got a peice of dust blown in from the cooling fan and its blocking the color filter internally. If you are capable you can take the tv apart and blow compressed air into the color block and remove the dust. Hope this helps

if this line is in the picture, that is possible burn in screen. if you have a black bar at the top or faint white lines that come down from top this is caused by defective filters in vertical circuit or bad vertical output. mch

Hi,
I hope your TV model is Sony KV-G21M1 and you see color bars as horizontal lines across the screen.
Let me now are you tech guy or know how to repair TV to guide you further.

Remove battery , let sit for 2 miniutes . Re install battery , in proper position , hold on button for a few seconds and this should work ...

I had the same horizontal, solid red bar along the top of the tv screen. I have an older analog Philips Magnavox TP2785C221. It just started all of a sudden. It was on every channel. However, the bar did not appear on the other input channels (e.g., AV1, AV2). So this meant that the red bar was only occurring on the antenna input. I unplugged my cable decoder box and restarted it. The red bar went away and that seemed to solve the problem for now.

You need to contact an ISF certified calibration professional.
