Later Electrohome color TV curbside find

[electroking]

I picked an Electrohome color TV set on the curbside on Sunday,
apparently from the early eighties with two detent tuners, UHF
stops at 69, 300- and 75-ohm inputs for VHF and 300-ohm only for
UHF. It's a 19-inch unit, made in Singapore, model 48CC41.
Does anyone have info about this?

After a two-day quarantine period on the back seat of my car,
I carelessly plugged it in. It works very well on UHF with the small
loop, but gets nothing at all on VHF, while I have four strong VHF
local stations. I suspect a busted RF stage, possibly from lightning
or something the like. Any other ideas?

(Getting a digital camera is part of my projects, so no pictures yet.
Sorry.)
