The other set that interests me is the suspected Sanyo
19" with digital tuners. They were very underrated.
Since they are free if you have a way of getting rid of the
carcases free take em all. You can experiment with them
& ultimately part them out or pass along.
That Viking 13" may be Sharp but looks more Samsung or GS.
Could tell with pix of back & label.
