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.

Tv picture sags


Projection tvs have a white colored cloth drapped over the pastic screen on the inside for the image to be projected on. This white film may have become unattached on the insid causing the sag.

Is the tubes going out on my rear projection tv?


If the red, green, and blue colors are separated like a rainbow, then the convergence amps are going out. This set has a common problem of two electrolytic caps going bad. The caps are in the upper left-hand corner of the main board and will have a bulged top if bad.
I would not think the picture tubes are bad, especially all at once.

RCA P52830BL picture is bowed and colors separated.


There is a convergence printed circuit board that likely has a few bad components. If you decide to get it repaired, the technican will probably check for fluid leaks from the picture tubes coolant area which has given problems on this model also. If the picture quality leaves a bit to be desired, it may be a wise move to upgrade to HDTV. A Sony KDS-55A20 model has a great picture and should be less than $2300. I just saw one at a local Sams Club store.
