First try to see if the fan spins. It should spin up at power on. If it does,
the problem is somewhere else. If it doesn't, try to give it a push with a
wood skewer. If it then spins up, I would use low pressure air to clean it,
and not bother with diassembly. Then, once the set turns on, set the high altitude option to on so the fans run at high speed. If the fan is dead, or
you feel like punishing yourself...
Remove the lower rear cover and the large rear fan. From there I think the rear fan housing, lamp power supply and a rear brace come out, but not necessarily in that order (its been a while). Then remove the screws (2?)
securing the blower housing. There might also be a plastic tab holding the housing in. Good luck. Let me know if you need a fan...
