You have a faulty power supply
this may be as simple as a few caps but unless you have worked on electronics have someone replace them or the power supply for you

Try this! There should be a power button on the bottom of the panel that has to be depressed for the television to power on. It is the main power supply button and without it there is no power going into the TV.

SOURCE: power wont turn on the red light in front of tv is blinking

You need some capacitors changed on your power supply. Easy job if you can use a soldering iron. I have a tutorial in my Tips & tricks. Remove the rear cover and locate the bad capacitors (little plastic wrapped canisters with swollen tops) near the top right of the tan PCB board on the left-mid side of the TV. Note the values written on then (1000uf or 2200uf) then head to radio shack and purchase the replacement parts. Ask for 16v or 25v parts (16v fit better). Replace the parts, put the rear cover back on and you are all set. I hope this was helpful.

I have the same TV and I just replaced the Capacitors. It came with 2 10000UF 10V caps and I put in 2 1000UF 35Volt caps from radio shack. Its like brand new. There is even a video on how to change them on You Tube.

My Hisense 55H8C TV does not respond to remote control or power button. If I switch on the main power plug, the tv is stuck at the last channel and sound output is through soundbar only. I have to switch...

Lots of modern electronics can be repaired by simply unplugging the AC power from the outlet and leaving it unplugged for 24 hours before plugging it back in.
Explanation... modern electronic devices are never truly "OFF" unless the power is completely removed. A logic state will get stuck and the easiest way to un-stick it is remove the power from the device long enough to discharge all of the capacitors on all the circuit boards.

Can't turn it on - the power lught is flashing

it is possible that the tv is in its power management system because it was over heated. Leave it alone for a couple hours and if it still doesn't turn on, try unplugging and plugging it back in.

Tv wont turn on

I had the same problem and took it apart. Before the repair there was no "click" when I pushed the button, a clue to the problem. The on-off button on the front pushes a weakly made angle piece of plastic inside which had broken. The plastic piece in turn is supposed to push an internal switch which is offset to one side.

I used epoxy (Araldite) to repair the broken plastic angle piece, but it still looks weak to me so I switch the tv off at the wall and leave the on-off button alone (though it does work now).

Opening the case requires some knowledge and care, and can be dangerous. It may void the warranty so be careful or give it to a qualified repair person.

Hope this helps!
