Just fixed my Samsung LN40 check fan #1.Unplug, Take the back off (like 20 screws were hard to find them all) fan is exposed in the middle. Unscrew fan, used q-tips and nozzle tool on vacuum cleaner to remove built up dust gunk. Blew in center of fan to dislodge dust. Screwed fan back on, plugged in to see if fan was spinning to cool TV. It was and the check fan message disappeared. Put the back on. Feeling Lucky no big repair.

hello Harley,
Lamp # 1 is lamp fan, Lamp # 2 is DMD board fan.
Lamp # 1 is located behind the lamp.
Pull assy angine out you will fine fan # 2 , clean it or replace it if not rotate properly.
Fans displayed on screen because fans are dirty or air flow not smoothly.
Good luck.

Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

Lol did you get a 3 wire switch ... they are made to use with more then 1 switch ie: in a room with doors @ opposite sides you may have 2 switches that work the same light or fan. This may be your problem, check the package ... if not check the switch, good luck!!

There is a slight possibility that fan #1 is still good. I would still investigate it though. If the heat is not controlled, more damage could be done. I'm not sure which fan is #1. I think on the PCB of the TV would have some kinda of marking that would say FAN 1, FAN 2, etc.

this is the fuser fan error replace them ur problem will be resolved

fan #1 is out
