The picture is only producing the basic colours red green and blue
The television will only produce colurs of blue red and green. Also there is a strange pattern appearing in the picture, sort of like a maltese cross along the length and breadth of the screen(in the red green and blue)

Hi. If it's not a picturetube (internal) fault, you may look for bad soldering joints on the printed circuit board, located at the tube.
This contains mostly the RGB amplifiers. A bad soldering on the one driving the "green" cathode, may cause such problems. It can easily be detected by gently knocking on the latter. Also look at the actual CRT socket solderings.
It is most unlikely that the fault is located in the colour decoder. Faults there mostly influence red and blue. In a PAL system, only red and blue are transmitted. Green is produced by a matrix.
Finally, in the worst case there is an internal fault in the picture tube itself. Usually, the discolouring is very bright, shows retrace lines across, and even makes the system shut down due to excessive beam-current. good luck.
Good day sir, your inquiry about the green lcd screen can be caused by several things. 1. The monitor/tv produces 3 colors, red green and blue, the tv mixes these three colors to produce the picture. a loss of red and blue produces this green screen. so check the cable, specially the red and blue jack of the component inputs, and the red and blue cable. 2. there may be loose contact on the signal cable. try using the video input instead of the component input. 3. the dvd player may have the problem, check the player component out jack. a loose jack port can cause these problem. hope this may help. thanks
First question is how old the printer is, The second is how many times have you cleaned the cartridges? In the process of cleaning there is a well that recieves the old and dried ink. This well needs to be serviced by a tech and cleaned.Make sure when you clean the ribbons you do not go across the colors, you want to go in line with the colors and use denatured alcohol don't use rubbing alcohol as this contains 60% water. Be mucho blessed... Mark
The green,blue,red hd plugs are for video only. you'll never get sound to produce out of a video line. audio comes from left and right which usually is white and red. it's always marked above or below the jack input.
your colour guns (that's what they call the light tubes that produce the 3 main colours, red/green/blue) need to be fixed. One or two of your guns need to have the liquid that protects the lens flushed out. I had the same thing and the repair man came in took the unit apart and removed one of my light guns (blue one) and showed me the dis-coloured liquid. He drained the liquid and added new clear liquid which protects the heating of the gun and everything was perfect again.
Hi, J !
You didn't say how old you set is, but to me it sounds like you may have a warped shadow mask in you picture tube.
A shadow mask could be compared to a piece of screen wire. It's function is to make the electron "beams" from the three electron guns strike the proper phosphor dot to produce the proper color- red-green-or blue.
If this is the case the picture tube would requie replacement.
