Am interested in any recommendations how to find either Service Manual or Schematic.

But, if the power supply is missing, all you really need is a 12V power brick with enough
current output? I'd start with any available power supply of 12V, and an ammeter, and the right
size of DC plug, then (after finding out what the current draw is) scrounge
for a suitable unit.

It's likely in the 3A range, probably pretty similar to lots of external hard drive power
bricks.

There's no guarantee that 12V is what the TV uses for voltage. For outboard bricks that I've seen, most of them have been 19V and above as it's easier to buck a higher voltage input into usable LED drive voltages. Still, on a TV with this small of a screen, 12V is certainly possible.

I'm surprised the back of the TV doesn't have the input voltage and polarity molded into the plastic where the port is.

I just looked at ebay, and there are a lot of universal chargers that purportedly fit the OP's model, but interestingly, every picture has the output voltage intentionally blurred out of the pic.
