Caroldickers,

if the picture have lost red, possibly there's a loose contact somewhere in C-board area of your screen. The only way to revive the red color is to check and resolder the c-board are.C-board is located at the back of the CRT unit.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

I have sound but the picture is purple and will not adjust with the remote or manually with the buttons on the tv what can I do to fix this on the philips 36pt41b129


The unit has lost its green video information. This can be a picture tube or a green drive problem. The only colors you are getting are red and blue thus the purple picture. All picture tubes have red, green and blue guns to make all the colors needed for a normal picture. It will take some troubleshooting to determine whether it is a drive problem or the picture tube itself. Have a repair shop check it out for you. A 36" TV is worth a check out fee. Thanks for using Fixya. Let me know how it goes.

I have a Symphonic 32" Color TV the picture is red. I need a tv repairman person to come out and look at the TV.


the dives or guns are out of balance. either the blue and green circuits are weak or the red drive is maxed out. when picture tubes are getting old, this normally occurs.
another thought is that the tint is incorrect and saturated. what is the picture quality details?

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Picture is fine, but the sound won't work


Are the yellow, red & white cables RCA phono plugs?

Yellow = Video
Red = Right Audio
White = Left Audio (mono)

The red, blue & green cables are for picture only and don't include sound. Have you tried using the red, blue & green for the picture and using the other cable, red & white for just the sound? Don't use the yellow.

Good luck!

Faded and out of focus picture


Your TV has a burnt CRT base socket. Replace that, it is not a tough job, but make sure that you get the exact same type of base socket.

How do I decrease the amount of green in the picture?


Unfortunately this model has a bad CRT. If is 3-4 years old and the greenish picture is in all inputs, for sure the picture tube is gone. If the picture is green only in component input check the connections for the blue and red cables.
