I would check the power supply for bad caps they will have a swollen top replace those and that should fix your problem

To all who are having power supply issues: Samsung is now acknowledging a problem with the faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

The slow turn-on is normally a sign of a failing power supply and certain conditions could cause noise in the digital circuits of the set. The clicking is likely a relay that is controlled by PS circuits that are detecting a fault condition and repeatedly disconnecting the AC. The late turn-on will eventually turn into no power on at all.
