Our cooling fan seems to be making a loud noise. Any suggestions?
My HLN5065WX/XAA has a high pitched noise that varies in intensity from where you can barely hear to loud. It continues for a few seconds after the tv is turned off. Is this a fan problem or does a bulb make a sound before it goes out? Any help is appreciated.
that's from a thermal switch, to keep the innards cool, post use. Seems to me that you might just check to see that all vents are open and clear of debris, for starters.
