No there are no fuses in that type of flat screen TV. If it will not power on at all then it sounds like a failed or at least failing power supply inside the TV.
Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will want to
contact a local TV repair person in your area if you are sure this is
out of warranty, more on that in a bit here. 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.

please check the connectors of power supply board, and reset all connectors.
if you have digital or analog tester,try to read the output voltage of the power supply
maybe no +5v going to mainboard..
or check the front panel board if its properly connected to mainboard.
thanks....give some comment so i can help you more....
