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.

KP-57WS520 Sony Projector - No picture

5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.

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.
