I hear clicking noise near the power supply.
This is usually and most likely caused by the power inverter/board. There are capacitors and other components that can burn out and will cause the power not to be transfered correctly

It sure sounds like the mainpower supply problem, the power supply may be trying to turn itself off because it detects short circuits.

Could be the power board or main board defective, but I suggest you do firmware update first. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 download the software.

Hello,
You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where, if otherwise
the power supply board is dead,do you 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.
Hoping that this will help to solve the problem.....

If the T-CON board is dead,you will see black screen (no picture) but you will see slight glow due the backlights is still on. Check the fuse and voltage on the T-CON board, dead main board will not be sending the voltage to the T-CON board.
But you are saying taht you cannot get any button on the TV to work, that will point the problem to be in the main board.
You will need service manual to really go in-depth troubleshooting.
