    yes the same problem is evident with my unit as well.

    even with the red focus all the way down it seems there are red shadows present, I notice there are 3 more knobs on the top row ?

Fix my line problem but red LED flashes five times


Hi Guys, Looks like your advise took care of the problem. I adjusted the power knobs for each of the RGB guns on my Sony 51 inch projection TV. The color looks great and I don't seem to have the blinking indicator light bugging me any more. I will be sure to suggest you folks to anyone with these type of technical questions.

GREAT JOB!!

Faint red curved lines on Sony KP 51ws500.Converged = no work???


Hi There!
This sounds like a typical problem related to a older CRT.
If you remove the front cover of the tv, you can then remove a wood panel. Behind this panel you will see a block (high voltage splitter) it will have 6 "knobs" on it, 3 will say focus, 3 will say screen.
They will also be labeled R - G - B  
Put the tv on a blank input so you can see the lines clearly on a black screen  - Find the knob for red, and SLIGHTLY turn it down until the red lines disappear.

Sony faded colours and double lines


You probably need to replace the convergence IC's and do a good cleaning of the internal mirror and lens. This repair will involve soldering and un-soldering on the printed circuit board. If you have no printed circuit board repair experience, play it safe, and have a pro do this repair for you as that price sounds reasonable for this type of repair. Good luck!
