I've enjoyed my LG C7 65” OLED for 8 months now. Last week, I learned about a protective plastic film on the BACK of the C7.
So I looked behind my TV and saw the film was still there on the back of the thin part of the screen (it did not cover any ventilation grates, it was overlaid on the aluminum—very hard to spot, and I'm thorough :] ). Unlike the film that was on the front of the screen, there are no labels telling to remove this. I don't recall anything in the manual about this either.
I've put in about 175 hours on the TV with the film stuck on the back. I’m concerned about the damage leaving the film has done to the picture, as it might not allow for proper heat dissipation.
And then there's the warning from LG, however incoherent (probably just covering their behinds?), which warns to remove the plastic immediately.
I game for 4-5 hours at a time on the TV, and never notice the screen emitting much heat.
Yet—I'm concerned about potential dimming or other damage to the screen that might have occurred due to keeping the film on for so long.
—I wonder if any of you who have left this film on can assuage my fears...who have compared temperature or other metrics to standard.
