With great technology comes great responsibility...
I'm on my second TC-P60GT50 and it's a "-2" model so something changed from my May '12 original that had no revision branding. The two behaviors I did different the second time, which has so far avoided IR and uneven phosphor wear, was keeping brightness limited to THX Cinema mode for all inputs and stretching input video to avoid black bars. (I stretch input using the STB so it's automatic.)
Based on my experience with multiple sets of the same model and getting IR/uneven phosphor wear on the first set, you're good to go without running slides and doing what I did above. Put the TV in the main position and enjoy it... the picture is amazing! It's too nice to put on the side.
