Will direct sunlight spoil an LCD tube?
Answers:
Yes, it also increase risk of fry your tv and even start fire contained by extreme condition. Not at all....you would enjoy to have a glass that could act similar to a magnifying chalice to even harm an LCD TV set....
And I doubt anything can injure it, EXCEPT for KIDS and their ability to verbs things without even trying.
We see that despoil all the time....
