Yes, it is either that or the "Startup Circuit" is faulty usually it is the associated relay. Thats the clicking sound you hear. When you turn on the TV, the relay is activated along with a timing transistor, the Relay has to make contact within a certain time frame. If the contact is not made during that time frame, the TV shuts down. This is a safety feature in all TV's. If you can get a schematic it will show you where the relay is or, after you unplug the TV and wait 15 minutes, you can take a look inside at the main circuit board, sometimes they mark the area with either "START UP" or "SHUT DOWN" and there you should see a relay.
But a new one usually has to be soldered in.

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...
