It sopunds like you have a color convergence problem, if this is the case and the CRT tubes are ok then you are looking at about $500 to repair the TV.

SOURCE: colour issues

Sounds like your red gun may be shorted, Try adjusting the red gun down a little see it that helps.You can also switch the blur CRT socket for the red if your screen is still mostly pink then you know for sure its your red tube that needs replacement. If its mostly blue then you have a problem in the red drive circuit.

SOURCE: tv gone green/blue and sometimes red in top right corner

If you have a Sony rear projection LCD TV then you have a failing optics block. LCD TV's are not affected by external magnets like CRT TV's were. The optics block issue will only get worse and needs to be repaired by a technician.

Pink color appearence when swith on tv for 1 minutes & wringles form on the screen


Hello

Pink colour denotes the absence of green colour dispay in your picture tube. I hereby gies an approximate voltages at the three cathodes of your picture tube socket solderings, and you just measure the voltages with reference to this. The voltages are approximate, and can chage up to 2% up or down.
Green Cathode = Pin number 9 [161VDC approx]; Blue Cathode = Pin number 8 [162VDC apprpx]; and Red cathode = Pin number 10 [157VDC approx]

If any of these voltage differes, the clolur related to that cahode will also rise or low, thath is if the cathode voltage goes very low, that clour will be prdominent, and if it goes high, that colour will not be there.
In your TVs case, the green cathode voltage now will be high. t may be due to a soldering loose to either to the picture tube base socket or at the terminals of the related transistor or Ic. It is best to resolder the suspected loose soldering points by applying a little more solder, as we in service field also do. It is very difficult to locate the exact loose soldering point and so I advice you to do so. If needs, replace the colour output transistors, of other devices if used. Just look at the voateg at pin number 9 at the picture tube base card. Resolder all the picture tube base socket pins. If you wants any more calrification, contact me through Fixya. Ok.

Sony wega 28 inch colours wrong, circle on screen


It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.
Thanks.

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

The colours on my tv have gone pink and green


Either your picture tube has gone bad or the transistor or IC on the crt board, on the picture tube, that feeds the blue gun has gone bad. You would have to test the transistor to see if its shorted or open with a multi-meter, or check the voltages to and out of it. The voltages are around 200v and dangerous if touched, best left to a proffessional. If its the transistor/IC it would be a cheap and easy fix by a repair shop, if its the tube, you may want to go tv shopping.

Pink colour


Hi there!
May be that the colour Amp is at fault or the tube is busy failing. Commonly it would be the colour Amp (Dry joints or faulty drivers). The Green is dead. I have had cases where power surge can magnetise the tube to such an extend that the whole picture will show one colour. In your case I doubt it very much. Good Luck,JUS004
