How to replace red crt on 52" RCA

I had repair man out to look at tv. had no red colour. he showed me that the light just above the board lit up on the green and blue, but not the red. He said I needed a new crt. does this sound accurate?? how do I replace this myself. I have researched as much as possible without becoming a tv repairman myself, and have taken apart much of the tv to get all the info needed. Including the number off the red crt. Or should I just scrap it.
model D52W26
serial G492CN05C
chassis ITC222
crt P16LXL00RFA(U)

When a red crt goes out and wont light its usually another reason such as a transistor or even faulty CRT pc board that causes it since the set powers up the other two tubes. Go to this link and leave them an email and list the model number and tell them the symptoms they will help you out with it, they are real good with the RCa sets. If the red tube was shot it would cause the set to go into shutdown or throw red retrace lines across the screen. Heres the link,

I have a light red hot spot just right and above center, any idea how to repair?

You have to take front projection screen off of tv. When you have taken screen off, turn on tv and observe light coming from the three crts. Look into the face of each crt and you will notice some contamination inside face of one of the crts. Most crts are sealed, so youll have to replace the burnt crt causing spot on picture.

I have a 52 inch RCA projection TV about 15 yr old today the colours are not lining up causing a shadow of red behind white lettering and looking like a 3 D show withought wearing the proper glasses?

you need to replace the convergence supply board, if it's one of the earlier models, you change the chip stk730-130 that will fix it. the board is small and up off the chassis to the right slightle, 4, 1/4'' screws holds it in place.
you might be able to get a whole new board, which would require no soldering to fix.

The RCA model is a 3 CRT projection TV. Most probably you need a new RED CRT, or there is a problem with the R(ed) channel (the picture is made up of 3 component colors: Red, Green and Blue). No way of telling without testing of the projector. Sorry!

Green light stays on but no picture

This is very hard to know the problem. A lot more info is needed to know about voltages on the inside of the tv. I would say to take it to a repair man.

Take off back cover--look to see if red tube is lit,if not
then voltages must be measured at red CRT circuit board.
One way to help diagnose is compare voltages to working tube
