Most likely neither, on the majority of Hisense sets it has been bad LED backlights

My Hisense tv model75h6570g has sound and a black screen there is no trace of a picture with a flashlight and the standby light flashes around 20 times before shutting off

Hisense only has 10 blink codes, on most brands they're helpful but not as much on Hisense, in 9 out of 10 sets it turns out being backlights, we've had sets before in our shop where an image wasn't visible, but it still turned out being bad lamp strips. Power boards are a bit different on Hisense sets as loss of backlights can put the set in sleep mode leaving only the standby voltage. Best way to troubleshoot the set would be with a backlight tester

No it will not be the tcon board clicking and if you see the logo that board is working. Your going to need to get some voltage readings from the power board and see if it's working ok for starters. Next would be unplug the backlight connector and see if the sound goes away, if it does you have bad backlights and I think this will be the issue

Hisense 58R6E no sound no picture?

This model had a lot of backlight issues with the lamp strips being bad, order a new set and install them and it will work again, but be careful handling the panel, it's VERY fragile

Where would the fuse be located on my 55 inch hisense tv

Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.

I have a Hisense led tv model F39V77C.

Yeah, replace the set since it appears to be trashed. But if you have a few bucks lying around you might want to try replacing the unit's power supply to see if that resolves the many issues you have.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
