@svsruof
you may have hardware incompatibilities, I will try to help you.
TV boxes is a pain story and you never know what you really have except if you investigate further your hardware.
You can try different miniarch images variants regarding your board (x96q) until one is booting, there are 5 different images for 5 different board variations of x96q (e.g lpddr3, v1.3, v5.1 ...) I don't know your hardware but keep in mind
that there are also FAKE boards with rk3228a or Rk3229 as x96q variants you have to investigate your Hardware first, rk322x boards are fake boards marked as H313 (on chip) and these are not compatible with Allwinner images (but you can still install Linux with other images for rk322x)
One safe method to verify if you have Allwinner board is to set it to FEL mode (by pressing the internal button with a toothpick) connect a male to male USB and then read your USB devices with lsusb command.
you can find more information here : https://linux-sunxi.org/FEL
Another problem that you may face is locked u-boot loader and/or device secure boot enabled by the manufacturer in this case you need to analyze the original manufacturer firmware (if available) to see the unlock possibilities or to try
to unlock it via adb (if possible). Serial debugging is a must.
Unfortunately i can't post miniarch images links here due to forum rules. however is very easy to find it.
If you are able to boot a miniarch image or a LibreElec image then is easy to install Armbian as well with some modifications on extlinux.conf
Tip: place a detailed image of both sides of your board. Someone may have the same and may guide you regarding your problems
