Question about Sharp Aquos LC-32G4U 32 in. HD-Ready LCD Television
If your power inverter is putting out voltage to the main circuit board, then you have a good chance of a faullty y sus board. If you have no power to the main board, then the power inverter is the main cause of the problem. They y sus board may also be tested with an ohmmeter by testing the continuity of each component like capacitors and resistors on the board itself. A service manual would be helpful for this.

Sounds like a failed or at least failing power supply / power board
inside the TV.
Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will need to
contact a local TV repair person in your area. This is actually the
most common problem with this type of TV, I see it every day, it just
happens - sometimes with new TVs and sometimes it takes many years for
it to happen.
If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.
If you want to attempt the repair yourself please let me know and I will get you the part number and a place you can purchase it from for what you need.
So sorry that I don't have better news but it is definitely a power issue internally.
