Sharp lcd screens are very easly damaged especially the larger screens,this could be at fault even though it looks ok,try shinning a light on the screen and checking every inch,could be the internal screen that has damage hence why not powering up.
Failing that it sounds like an internal short.

Sharp has had some issues with the sound being distorted or going out totally on several Models.
It is mostly caused by a Deteriorating Heat Transfer Pad. As it deteriorates and liquify, it becomes conductive and shorts out the Audio Circuit. The proper way to fix it is to take it to a Sharp Service Facility and they must remove the Board the Pad is on and clean the old pad off, Clean the liquefied
mess off the board and install a new Heat Transfer Pad, them reinstall the Board. It is not a easy job and it is a messy job.

The PNL-POW (LCD panel Power) and the PS-ON will be 0V until the main board send out the signal to turn them on, it is working.
Do you get backlights?
Did you check the fuses on the Inverter board? You power supply is working.

Good day to you and welcome to fixya..
That problem is usually have 2 causes..Its either power supply board or main board..
Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
You have a better chances if you have failing capacitors on the power supply board..
Please watch this videos about capacitors..
Hope this solution will be helpful..
Thanks for using fixya...
