Samsung rear-projection televisions use a bulb inside of them to create light for the pictures that are displayed. There are one or two fans inside of the Samsung to help keep the bulb and electronics from getting too hot and burning out prematurely. A defective fan must be replaced immediately or the bulb and electronics inside of the Samsung will be at risk. You can save money and time by replacing the fan yourself, once a replacement fan has been purchased from a TV supply store. The modular nature of the Samsung’s construction lets you get to the fan without having to remove any of the other components. It is opened up in a similar fashion to other rear-projection TVs.
Put on the work gloves. Turn the Samsung rear-projection television around so that the back is facing you. Use the Phillips screwdriver to remove the screws from the bottom left, the bottom right and across the bottom of the TV. Remove the screws that are directly above the ones on the bottom left, the bottom right and the bottom of the TV. Put the screws aside.
Insert the flat-edged screwdriver into the seam between the bottom plate and the back of the TV. Wiggle the flat-edged screwdriver into the seam to loosen the bottom plate. Remove the bottom plate and put it aside.
Locate the fan assembly inside of the TV at the left corner. Use the Phillips screwdriver to remove the screws from around the fan assembly. Put the screws aside.
Pull out the fan assembly’s power cable from the connector inside of the TV. Pull the fan assembly out of the TV.
Use the Phillips screwdriver to remove the screws from around the defective fan in the fan assembly. Remove and discard the defective fan. Insert the replacement fan in the position that is now vacant. Use the Phillips screwdriver to attach the screws to the replacement fan.
Place the fan assembly back into its position inside of the TV. Attach the power cable from the fan assembly into the connector inside of the TV. Attach the screws to the fan assembly using the Phillips screwdriver. Screw the bottom plate back onto the TV using the Phillips screwdriver.
Make sure the Samsung has been unplugged and turned off for at least three hours before opening it up.
Do not replace the fan yourself if you don't want to void the Samsung warranty.
