How to turn off auto standby on my Hisense JJOA6200 please?

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

Are you able to get some voltage measurements?

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.)

1. Open internal fuse

2. Power supply failure

If it is asking for zip code you have not told it to scan for over the air or antenna channels when it asks air or cable

If standby power light is ON, and the set do not come out by standby mode to ON, the fault is with its main board. If standby light too is absent [not light up]; the fault is with its main power regulator board. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

Call the HiSense tech dept. You can find the number on line and they will tell you how to fix it or you can try using the remote and go to settings and see if you can fix it that way. Also the manual for this tv should be available online as well.

STOP!

The unit has a fault on its power board and sustain board.
It turns off because the sensor is preventing some component from bacoming overheated and catching fire or damaging further components. Seel professional repair.
