Fan #3 is the LED PCB fan to the back right as you look at the back of the set. You'll have to completely pull the tray out (not hard) and the fan is right there in the open to the right behind fan #2 (the larger fan).

You can attempt to remove the back cover, but there is a very delicate mirror in the back. I'd just move it away from the wall, used compressed air to clean out the fans, and put everything back together. Just make sure you don't damage the color wheel or light engine.
These televisions need alot of air flow to keep cool. Sometimes dust can buildup on the fan that is already running lots, The weight of the dust besides the heat can wear these out. You can check the wiring to the fan with an ohmmeter or multi-tester to see if it is getting 12 volts any at all. If so, then fan is probably bad.. If not, then you may have a more serious problem
If you take the rear of the set off and hold the Interlock Switch on the right side up,Turn "ON" the set and look for three fans,one of them will not be turning. There are two small fans and one large one. The Large Fan is the Lamp cooling fan and the two fans are for cooling the Ballast and the other one is for cooling the DMD chip Heat Sink. The two smaller fans are the same type. The Lamp Fan (Large one) part# is BP31-00024A and the two small fan #s are BP31-00001A. They are all easy to replace.
the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note: The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.
and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure
Quite possibly; the set apparently is sensing the operation of the cooling fan and that is probably defective.
These sets generate a great deal of heat in specific areas and with no fan, they would quickly fail from heat alone.
You should be able to spot the likely place for the fan if you remove the lower back panel of the set.
If is probably a 'commodity' fan that is available from multiple sources; I wouldn't go to Samsung first since they will mark it up a bunch.
If you can gain access to the fan and it isn't just being impeded by an accumulation of dust, get the make and model number of the fan from the label (almost always present) and do a search on the information you find.
You should open the back panel. The fan for the lamp module is the one on the right.
There is a fan on top of one of the metal cage at the center. With the power turned on you should see that they are moving. With the power off, blow out the dust with compressed air and then vacuum. Do not blow into the fan on the right as it will get all the dust into the lamp module.
