Question about LG Televison & Video
You haven't stated which exact model, but yes, on many electronic devices the cooling fan speed is automatically controlled according to need. Most current flat panel tv's (except for ultra budget, old technology "no name" designs) incorporate this feature.
This cuts fan noise, prolongs fan life, and uses a little less power. Just make sure that the ventilation slots on the tv are not choked with dust, and on models with removable gauze filters make sure that you clean them every month or every week if it's a dusty environment. Removable filters are more commonly fitted to LCD projectors, but I've seen a few flat panel tv's with them fitted as well.
If the fan becomes especially noisy or stops altogether (some designs do allow the fan to stop for short periods though) then you must get the tv serviced as a failed fan is cheap, but an overheated tv can be more expensive to repair. They all have thermal cut-outs which usually put the tv into "protection mode" if the tv overheats, but fault diagnosis is usually faster and cheaper if this can be avoided. Much better to avoid letting it overheat to begin with.
Relax and enjoy your tv :-)
