Re: colour on tv is all purples and greens

Was the tv dropped?--try manual de-gaussing.If that does not

work,the problem may be the shadow mask inside CRT or the

yoke is loose and mis-adjusted on the neck of CRT.

Check for any loose soldering points on the video output card [ a circuit baord located at the neck of the pircture tube]. Resolder all the suspected solder points. Green colour out put is absend now with your Tv.

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.

Red, green and blue colours diveded on my TV

ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

Tv turns purple and green if on too long

try dusting out the inside, or maybe using a vaccum hose to get all the dust out.

Screan turned a shade of purple

I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).

Purple and green scrolling lines

This may be a mechanical or electronic problem that is dealing with the sync of the colour wheel. There is basicly no colour lock. This may be the replacement of the associated circuit board, or the motor assembly or the colour wheel.

The link below is describing about how DLP technology works. They are relating to a front projection type. With the rear screen type, the basic technology is very much the same for decoding the pictures from the TV signal.
