Playing DVD's the colour is mainly pink or green

Hello,

First check if the cables are properly connected to the television, then ensure the problem is not from the television by hooking up another player to it to see if it plays fine with good picture.

If it does the same, then you need to know that the problem is from the television and not your player, but if the image is clear, then you need to know the problem is from the player.
Such problem might be caused by the AV port or from the main board.

Try to assess the main panel to see if it has some lead melted on it causing there to be a bridge of two capacitors together, also you can check for bad capacitors. If you detect any of these to be the fault, then correct bridging leads by using a soldering iron to break off the bridge of lead, then melt off the bad capacitor and replace it with a new one if that seems to be the problem.

Take care and good luck
