Question about Televison & Video
This problem denotes a possible shutdown circuit activation caused by excessive current flow from the IHVT. This might be caused by a shorted horizontal output transistor, or a shorted and or open transformer (Applies to CRT type TV). This also can denote a switching power supply shutdown circuit problem (Applies to LCD or Plasma TV). Both of these issues should be checked by a qualified TV technician.
I hope this helps, Shuttle83

The clicking noise is caused by the relays on the power supply board trying to power up the system. Your TV has detected a problem that's causing the power supply to shutdown. Someone knowledgeable in electronics can track down the problem. The SOURCE of the problem could be another board other the power supply.
