*first-time poster - please let me know if i should move this message to another area* I finally broke down and bought my new tv yesterday, and my hopes were immediatealy crushed when I powered it up and found red/green discolorations in each of the four corners of the screen. There is no nearby interference (speakers/computers/etc.), and I left it off for 12 hours and the problem is exactly the same. I also played with the geomagnetic interference settings, which had a very slight positive effect. Any ideas of what it might be? And would I be better off seeking service or just exchanging it? It's certainly not fun to move around, but if this problem would suggest there will be more down the road, or if fixing it would be invasive to the point that more damage would be done, I'd rather just get tough and pack it back up and exchange. Many thanks for any thoughts!
