How come when I turned Mt hisense TV off and when returned it won't turn back on?

The first links says 10 blinks is the max.

If your Hisense TV won't turn on, first ensure that the power cord is correctly seated in the back of your TV and then try a different wall outlet. If the TV still doesn't turn on, unplug it from the wall, wait 60 seconds, then plug it back in.

The Hisense EN3G39 is the remote control for the 55N8700UW, 65N8700UWG, and other TVs. I have never seen an option for removing the standby mode from any TV without a change to the firmware. The TV will always return to the standby mode when power is returned. The type of firmware change that you want will not be available from the TV manufacturer.

The smart plug is great for reducing your power bill when you aren't watching TV. It won't avoid the turn on step.

I wish that I had better news for you.

(I wouldn't recommend trusting a third-party firmware if one exists or was created for your TV. That would void any warranty and could cause problems with the TV.)

Ok so this one is complicated In my experience with this type of issue if you remove the back of the tv and look for a swollen capacitor as u can see on this pic of what I am speaking of. I had a 60 inch flat screen did the same thing. I opened it up found the one that was swollen and on mine there was only one I removed it desolidered it I went to Apache reclamation it’s a store here in Phoenix that is like a thrift store for machine parts and things like that. I m sure you could probably order one from eBay. Anyway we found the one we need and it was a little larger in size but was the same voltage and soldiered it on to the board and the tv now works. If you think you could take that on go for it. You won’t make it any worse right?

Take it to a servicer with proof of purchase or back to the store. You will get it repaired for free or get a new TV.
