Do this FIRST....

 

If you are using the 5 wire Component connections on your TV set, I'd like you to remove and reseat ALL connections on the TV set, and the unit that's providing the purple picture -- if your Cable box and your DVD player are showing a purple picture do both of them. If only your cable box is doing this, then do the cable box only.

 

Make sure they are fully seated after removing them, we want good contact.

 

Now, if that does not fix the purple picture, then activate the TV's menu and see if that is affected by the purple or not.

 

Let me know the results of your tests....they will help me to identify whether we have a problem with oxidized cables, bad video board or possibly bad gamma on the TCON board.

 

Are your darker sections of the picture also turning Purple, or ONLY the White sections??
