What brand and model ?? 3 years old does not mean anything. I've seen brand new TV's with bad CRT's and other problems. Some brands have a bad patch of CRT's I hope yours isn't one of them.

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.

Hp w2007 why does the computer go pink everything that is green is now black


All the colours on the screen are created by "mixing" the 3 "primary" colours (red, blue, green).

Once the production of "green" ceases, anything that should be "100% green" becomes "100% black",
and every colour that indicates some percentage of "green" becomes a mixture of just RED and BLUE, i.e., various shades of PINK.

First, try the monitor on another computer (desktop or laptop). If the problem persists, it's time to replace the monitor. If the problem vanishes, it's the video-card in your computer that is not generating GREEN, or it is the "data" cable between your monitor and your computer that is not transmitting the GREEN request. So, you can try replacing the data-cable, or try replacing the video-card.

Red colour appearing on screen


Your tv could have one of several faults. None of which are to be tackled by anyone except a qualified engineer due to the electric shock hazard.the first problem could be the crt (tube) the second could be the componets on crt base circuit board ie resistors or ic.
With a tv 9 years old it may not be economical to carry out a reair.

Samsung LE26R7 4BD, approx 4 years old, colour distortions


Check all of your cables on the back of the tv and your sources such as Cable,Sat box and DVD palyer to make sure they are fully inserted into the input and output connectors. Some times Component cables will work loose and you end up with a missing color. Temprature changes can affect intermittant connections. If that does work then you have a bad Main bd.

Pink colour everywhere


Assuming all power supplies are OK, you most likely have a bad CRT grid, and that respective (red) tube must be replaced. I'm sorry that it went that way, as this repair is not cheap....accordianman

Color problem with TV


Are you getting Green or purple or pink patches all over the screen?
This could be a problem of Degaussing. Have you placed any Magnetic source near the TV recently? Some Tape recorder or walkie talkie or a Speaker, etc? The Magnetic field created by any of the above sources can cause coloured patches over a colour TV screen.
It also happens if you shift the TV from one location to another.

The third possibility is that the Picture Tube's Red Output stage gone faulty. Unless you are a trained Solid state Electronics Technician, there is nothing you can do. Better go for a trade in.
