I could hardly pick the transformer up. It was almost too hot to hold.

It shouldn't get to that kind of temperature. I would return it. If
the replacement is as hot, then select another product.

Agreed. Are there any ratings on the "transformer"(*) and on the TV? What
was the power source when you were using it 12v or 240v? It's not 100%
clear if the "transformer" is needed for 12v operation.

(*) I have "transformer" in quotes as quite often these days they are
really small switched mode power supplys rather than a lump of iron and a
couple of coils. Normally easy to tell as iron is quite heavy, circutry
not. I'd be surprised if a SMPSU would run down to 12v though most have a
lower voltage limit somewhere above 50v.
