@mark43174 you have not told us what you have checked. The no video issue can be related to a bad backlight inverter circuitry. A simple check for that would be to darken the room and turn the TV on. Then use a flashlight and angle the light at the screen on different areas. You might make out some shadows, The Splash screen or see a slight grey color. Your model uses an backlight circuit on the power supply board. So replacing that should repair your TV.
If you do not see anything, unplug your set and remove the back cover. Then visually check the boards for any obvious damaged components. Check all the wiring and unplug the wires and plug them back in, make sure they are properly seated. Post some images of all of your boards with your question. Use this guide Adding images to an existing question for that so we can see what you see. It is possible that this is either a power board or a T-con board issue.
We will need to know if your TV is a Hisense 32H4C or if you just picked it as a device.

When you put a flashlight up to it, is there picture ? You may have to look at it from an angle. Look all over and try turning it off and on, you may see the Hisense logo.
