After 2 or so years, I still love my 60ST60, but the image retention is unmistakable and has just been getting worse. If I'm watching TV and bring up the Guide to see what else is on, when I change the channel the outline of the Guide can be seen for up to 5 minutes. And HGTV seems permanently burned into the lower right corner. Been running screen swipe overnight for the last couple weeks, doesn't help so I'll probably stop doing that.
I have the Best Buy Black Tie warranty which covered image retention when I got it, so I'm thinking about cashing in on that. I assume they'll give me a monetary credit since there are no more ST60's... but maybe I should wait a little longer until there is a suitable replacement. I need black blacks and a uniform backlight. Nothing bothers me more than edgebleed and flashlighting.
