Start fromt the plug and move on to the fuse, the coils, the rectifier, and the SMPS. If there is mains on this stage and there is no output of +B then you need to replace the SM drive/Transformer/ allied components. If +B is present and the set does not trigg, there could be the main board failure.. it might prove difficult if your are not familiar with this PCB... Just check this out

It will more than what the TV is worth, the panel is the most expensive part of the whole TV.

Have you tried the reset buttons on the back of the TV?
It should be right below your Cable IN port.

If that doesn't work, you may have to take it into a repair shop for the main unit board to be replaced. The part # is KD352

That click sound when the tv turns off is normal, that is just the relay from the power supply shutting off.

When you turn the tv on, do you hear a faint “pop” noise from the speaker? If so, the problem is with the heat sink under the audio IC. Over time, the heat sink will lose its consistency and start to melt, thus shorting out the audio circuit. To fix, you’d need to clean off the melted residue on both sides of the audio IC as well as replacing the heat sink with a newly redesigned Sharp Heat Insulation Pad. It’s a pretty complicated fix, I suggest calling your local authorized sharp service center to fix this problem. The part is inexpensive, so you’re most likely looking at a labor charge (maybe around $200ish) for the repair if they are not marking up the price too much.

Check the high voltage circuit on the board that has the 120 volts input. The high voltage should be close to 400 volts - nothing less than 390 volts. The capacitor is failing to hold the voltage and needs to be replaced.
