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.

There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

The colour has gone wrong on my tv it show the the green and blue pigment but not the red. wil this be an expensive repair?


This problem could be as simple as poor solder connections on the board that sits on the back of the CRT to a defective driver transistor for the red gun to a bad picture tube. It is possible that this is an inexpensive repair (solder connection or defective transistor) or expensive (bad tube). If you can solder, try resoldering the CRT board connections and see if that resolves the problem. If not, then have a shop take a quick look. They will be able to determine whether the CRT is bad or not.

Toshiba colours gone wrong


Yes it is repairable. One of two things is wrong. The color wheel is going bad or the DMD board is going bad. These are the most common repairs needed for a Toshiba. I hope this will help.
