Question about Samsung HL-R4266W 42" HDTV-Ready Projection Television
My TV's fan sounds like it is working in overdrive. It is very loud and constant. This TV has never been worked on by myself or any tech so I am certain that this was not done through poor repair or self repair.
Your best bet is to unplug the tv give ten mins to allow the capacitors to discharge get a flat table with a sheet on it lay the tv face down remove the screws which hold the back cover on locate the fan look at it carfully to see first of all it is seated in its housing or the fans housing is screwed or clipped in its holder properly if everthing is as it should be remove the wires off the the fans connector remove the fan revolve the fan see if it makes any noise at all then see if there is any play in the fans bearing buy rocking the fan back and forth see if there is any signs of where the fan is catching the side of the fans housing if your not sure leave the fan out place the back of your tv back with a few screws plug it back in turn your tv back on see if the noise goes if not its not your fan the fan is acooling device so don,t leave it out any lenth of time otherwise the tv,s ciciuts will overheat yates210456

I remember happening to us many years ago. The cause was accumulated dirt and loose insulation material interfering with the fan blades. The solution was to unplug the refrigerator from the wall outlet, move the unit to enable reach from the back, unscrew the screws holding the back cover located at the bottom area (made of kind of cardboard), with the vacuum cleaner thin long nose attachment clean anything that looks dirty the best you can reach. Look for the fan and check nothing is interfering with it. Clean it, use a thin brush the best you can. Be careful not to hurt yourself scratching a finger or break anything bumping around cleaning. Some refrigerators design allows to reach the condenser panel (kind of a radiator or grilled looking component), if you can clean that too it will get your unit working efficiency back to maximum.
Another cause for noise could be the freezer fan hitting frozen condensate caused when the door gasket is deteriorated or not sealing well (humidity seeps in and freezes interfering with the fan operation). While you are at it look for any freezer stuff (content) sticking into the freezer fan cover and touching the fan, that may make noise too. Good luck.
