The P52926 uses the PTK195 series chassis. The middle "rear projector" is actually the Green Picture Tube. If the red and blue tubes are working then all major components of the set are fine. The only things I can think of that would stop the green tube are cracked solder joints on the green picture tube socket PC board or an open high value (100k - 120k ohm) resistor on that board. If you do not have experience testing and replacing small parts or resoldering boards in a projection set then have a qualified tech handle it for you.

Picture is distorted and colors are wavy almost looks like the picture is doubled and color doesn't look right

You can try a new lamp, use the convergence feature to align the three lcds inside. If it doesn't work, you need service.

Sound but no picture. I'm thinking I need a new picture tube but how much is it going to cost me?

First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
