[cisco-voip] LCD of Phones gets black when room temperature is over average

[Anthony Kouloglou]

I had a 7941 phone in a room with no air condition and after a night in 
there
the next in the morning the lcd was black!!!The room temperature was 
around 35 degrees celcius.
Will it be OK if the room cools?
Will it be permanent?

Thanks
Akoul
