Sony kp-51ws510 Rear Projection HDTV - Picture quality is fine, just doesn't have any red's in the picture. What shoud i look into?


Make sure the cable box or DVD/Blu Ray player is hooked up properly. Sometimes one of the component cables can become loose and lose the reds.

The red tube could be shot also. My old projection tv had the green go out. Believe it or not the whole thing can be replaced, but to replace a CRT on an older model can cost a lot.

The picture is is now in pink


If Sony KP-51ws510 it is an common issue with the picture tubes but there may be a simple way to adjust something in the set to correct this--these had problems with the 3 picture tubes where it can go to excessive red, green or blue.

Confirm model and issue and I will assist.

It only requires a screwdriver and the back does not have to be removed in this case.

The tv picture looks like should be wachting it whith 3d glasse


This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

You can see some example photos and find a solution here on Fixya.

Pink image on Sony KP-53HS30 TV


Pink? If this is a retangular box that appears then I would suggest to look into the fact that you have turned on "TEXT" mode within the "CC" closed caption settings.

Colour misalignment and focus


You need a new convergence board. Not an easy fix, sorry.

Hi Ross, This repair is quite easy, But before I tell you how to fix the problem I need to know have you gone in to the user menu & tried adjusting the convergence This will save time & expense for you ? If you havent then try this first it may sort it out without needing to dismantle the set. Let me know how you get on by either replying to this post or let me know via email [email protected] Chris..
