Hi.The ballast may be defective if you hear constant clicking sounds after you've pressed the power button.

If there are no clicking sounds after you press the power button(3-5 clicks every 2-3 seconds), this will confirm optimal ballast performance and, it will also confirm a major issue that concerns the Power distribution board. There are several weak or damaged components on the board that have failed.

The replacement of the power board is recommended in this case.

Samsung HCL4715W will not power on


At five years old, I doubt it will be worth replacing the power supply , a picture tube or two and possible the signal board. Cut your loses and get a new set.

Loud electrical sounds


It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.
