my tv has been doing this for a while now and happens a lot more when i use it to watch movies on my blu-ray player but still happens every so often when watching regular cable. see pictures
as you can see the color gets messed up but only on certain colors and it only happens when it is first turned on then goes away after a few minuets. it has been in the repair shop for almost 2 months cause it is still under warranty and i called today asking what is going on and they said that they could not reproduce what was happening even though the owner of the repair shop came to pick it up and saw for himself what it was doing. they told me to take a picture of it the next time it happened and guess what, as soon as i turn it on it happens.
