Yes there was an issue on the 2011 models with the screws on becoming loose and shorting out circuit boards, usually the SC board. I learned about the screw issue thanks to this forum, and when i had to have my SC board fixed on a tc-p55vt30. After that I opened up my other my other vt30 and sure enough they were looss, was one screws actually arcing on the SC board.
I ordered replacement screw kits (about 18 screws) and replaced the grounding screws on the 3 boards on the left side. The news screws have lock washers on them. So if you have the back off anyway, it wouldn't hurt to check to make sure your screws are snug. But, i don't think 2010 models had this issue.
