The clicking could be a loose connecction of the power plug or frrom the main power unit of your TV. Remove your plug and see the ends for burn outs, if so clean and use a different outlet. If not open the set after disconnection and check your main power supply unit for loose connection particularily in the surge protector, the main capacitor, the main drive, diodes or connectors. Wait to hear the sound and use a long insulated rod as a probe to confirm the origin of the sound. Solder or replace the damaged item. Hope this helps . Good day

On your Plasma tv you have cooling fans on the back side you will need to check to make sure that they are running. Lay your tv on the bed take off back cover (it's not hard) and used some air-in-the- can to remove dust from the back! If you need a fan go to Partstore.com (1-866-925-PART)
