WE bought a 2008 AS which had the old-type TV which doesn’t work on the new HD frequency-band… and picked one up at WalMart (21”-?) for $99 which was a direct-fit on the existing swing-out mount.
Although it had a 120 Volt AC power cord…it actually had a small “brick” incorporated in the cord which converted it to
12 volt DC…. so we were able to discard the 120 volt cord and (don’t recall if I kept it and used an electronics-store adaptor-plug…or if I cut the plug off the cord and wired it into the AS 12-volt outlet at the antenna amplifier….) but that meant it was useable on the AS battery whether we were plugged into shore power or not.
We also bought a CD/DVD/BluRay player that is
12V and can watch movies etc even if we’re boondocking.
Here’s one at Walmart for $89. You will have to look at it to see if it also is a 120VAC-12VDC power-cord-type…but I suspect it is.
