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.

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

SOURCE: 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.

SOURCE: I need to purchase a colour wheel for a Sony LCD TV

This is a LCD type rear projection set and should not use a color wheel--only the early versions of DLP sets used a color wheel and if they did--Sony never (at least in the USA) sold them --try this link to see if it helps you where you are.

If this helps you rate this solution as I do this here for free.

Can see image but the screen is all red


Generally Tv screens use three different colours to make the picture, and if one or two of these colours don't show you will see the picture but in specially one colour (like looking through a red filter in your case).
If you are using an input into the TV (DVR or Games console etc) then I would firstly move the cable around in the back of the TV and the console to see if anything changes or flickers in and out of being correct. If this does happen I would recommend buying a new cable to fulfil the purpose.
If this does not happen and you are still seeing red then there may be an issue with the connection inside the back of your TV, this shouldn't be a very expensive issue to fix as you are still getting a picture but I would recommend getting a specialist to check it out if you are not confident in fixing this manually.
Thirdly and most unlikely is the settings inside the TV have changed, some TV's like yours will allow you to change colour settings on the screen. I would go into the menu and find the section that allows you to change the colours and have a check to see if any of the settings seem off.

the problem with LCD tvs are that they have back lamps that shine thru the LCD sceen. the job of the screen is to block the light of the different colors to make the picture. the problem is that the very thin screen can not block all the light. if the set has a back lamp setting turn down the back lamps and adjust the brightness control it should help a little. you my notice that the blacks and dark sceens look better when the room is fully lit and look much worse in a darken room.

I have an LCD TV. All of a sudden the picture colour has gone wierd. The best way to describe it is that it is similar to either a colour negative or one of those scientific 'false colour' images. This...


TFTs can produce a wide array of colors, but it takes an enormous number of transistors to make up a display, and a problem with any one of them creates a defective pixel on the screen. Typically this shows up as a bright spot on a dark background, caused by a damaged TFT failing to turn off a pixel. Most active matrix displays contain a few bad pixels, but a few bad pixels are not going to have much of an impact on the overall picture.
The properties of liquid crystal material can create problems with viewing angle effects, causing the image to darken, disappear, or reverse the dark and light tones when the viewer is not directly in front of the display (kind of like looking at the negative of a photo). The light bulbs make LCDs heavier than the plasma TVs (though they are still lightweights compared to CRT televisions.
Benefits of LCD TVs include a picture that can't burn in and doesn't deteriorate over time. Because of their flat-panel nature, placement options are plentiful, optimizing the cool factor over standard TVs
