Clear but only blue/green color


Do you have a component cable hooked up to the TV? (cable with RCA connections Green/Blue/Red/White/Red)

If so you want to check that the red cable is tightly connected to both ends (TV and whatever it is connected to).

Good Luck...

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.

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.

Green & red tint


Most likely nothing you can do to fix this. CRT TVs use 3 colors to make an image on the screen (Red, Green, and Blue). If you're only seeing red and green then chances are the blue has stopped working. You can replace certain parts in the TV but for a 27" TV you'll probably end up paying more for the repair than a new TV.

I don't recommend taking the cover off and trying to fix TV yourself without training. CRTs have a lot of electricity stored in them (even after turned off) and you could accidentally electrocute yourself.

After a few minutes the color goes to intense red and green


My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

Green is not being displayed on my TV


If you have experience troubleshooting solid state TV sets, you should be able to tell by a couple of voltage measurements if its a problem with the picture tube or the drive circuit. Simply take the multimeter and compare the base voltage of the green drive to the red or blue drive transistor. If the voltage is about the same, measure the collector of all three. if the green voltage on the collector is higher then the others, then theres an open between the drive transistor and the crt element. this could be an open resistor, a bad solder connection on the crt socket, or an open picture tube element. If theres no voltage there then your going to have to trouble shoot the drive circuit.
