Disconnect all attached components and the power cable from the outlet. Manoeuvre the DLP to allow access to the rear of the television. Allow the set to cool for at least one hour if it was recently used.
Remove the rear panel of the television and locate the cooling fan. It is usually located at the rear of the television casing near a grated opening for ventilation purposes. If multiple fans are installed, the cooling fan usually is the larger one. Avoid unnecessarily disconnecting any cables or components from the television.
Remove the projection bulb and set aside to avoid any damage. Avoid touching the bulb surface directly to prevent any permanent damage to the bulb. Note any cables or screws that you remove to allow you to reinstall them correctly.
Unscrew the cooling fan case from the television housing and carefully remove it from its place. Disconnect any power cables from the circuit board that is connected to the fan. Remove the fan from the housing or replace the entire housing, depending on the manufacturer. Use compressed air to remove any dust or loose debris that can damage the television components.
Secure the fan to the television. Connect any previously removed cables. Place the projection lamp housing back in place and replace the cover on the rear of the television. Power on the television to ensure the fan is active and no unnecessary noise is present.
