My rca rear projection tv screen turns mostly green after being on for about 2 hours and the writing is blurry


Not an uncommon problem with projection TVs. The image is projected onto the screen by three high intensity lamps located in the base of the unit, one tube for each of the three colors necessary to recreate the video signals. (red, green, and blue). Direct view TVs have all three built into the neck of the picture tube. The from each of these colors are controlled by signals and voltages applied to wire mesh screens, called grids, that are part of the tube. Sometimes these internal grids fail in such a way so that as the device got warmer the wire in the grid flexes as it gets hot and at some point contacts something else in the tube. In your case, assuming that the picture is good until the failure, the green tube loses control, goes into overdrive, defocuses, saturates the display with green. If you open the unit, you can see the three tubes and verify the failure. The proper fix is to replace the faulty tube. Sometimes opening the unit will keep the internal temp cool enough to prevent the failure. In a pinch, (Superbowl Sunday, 2004), a cooling fan installed in back worked. I hope this helped.

No Red color at all. The convergence feature does not work either. Lots of green and blue RCA Model D52W59


Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !

RCA P52731WK REAR PROJECTION NO RED ON SCREEN


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!

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

Hi I have a 52" RCA big screen tv that is only 3 years old however we turned it on today and it is showing some red blue and green lines and the picture is blurry


Hello clara7,

This denotes a convergence problem. I would suggest that first you enter the menu of your TV ad try to do an auto converge on your set, if this does not work I would suspect that the convergence ICs have gone bad and need to be replaced. I would suggest that you have a qualified TV repair technician replace the convergence ICs in this set.I hope this helps,Shuttle83http://www.electron-age-technologies-llc.com

RCA P46921. Just changed flyback.


First, this assumes nothing else is going on to cause it. Here's what I did. Go to the 'green grid' via the v76 menu and go through the alignment there. Notice that there are red letters, blue letters, and a green grid. While you are in this screen, adjust the red, green, and blue focus watching the individual color's item until they are in focus. If they won't focus here, they won't focus and you have something else wrong (what I do not know). Then, return to normal programming, then select menu on the remote, then screen, then adjust projection tv convergence both horizontal and vertical crosshare. That ought to get it.
