If you are missing one of the colors but still have an image (red, green or blue). Real simple, turn on the TV and see if there are any colors missing from those. Most rear projections have a color bar you can put up or a converge feature which is used for aligning the colors for a clear picture.
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!
It sounds like the CP150 and or the CP114/120 capacitors need to be replaced, they cost around 3 dollars each and can be found at Radio shack or you can order them from http://servicemanuals.vstore.ca/ and they will send instructions with them.
My RCA 52 rear projection TV has the letters getting blurry on top and bottom, Picture is OK but visually losing my eyesight staring at blurry numbers and letters.
sounds like your color guns are out of alignment and need adjusting. its a cheap fix with a tv tech but i wouldnt recommend doing it yourself. plus, a visit from a tech can tell you if there is anything else wrong/about to b wrong
ok go into setup menu.... go to convergence.. try to adjust convergence .. does the crosshair move up and down side to side... if not then you might hqve q poblem with convergence power supply if they move then u might have s setup issue
Pull out the plastic pieces (green , red and black) and pull slow out the red wires come from fly back, box focus-screen and 3 red wires from CTR. Keep attention in position wires ( for put it back). You will take out 2 screws for splitter box ( one in the front other in the back side)
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
