Success.
Retirednoguilt was kind enough to post Power supply on ebay shows a fuse in the photo :
I think there might have been one other for sale somewhere in the world, but this one was in Baltimore**.
As I mentioned maybe 8 or 9 weeks ago, even though I'm in Greece, the ebay product above was for sale in Baltimore, where I'm from, and where my friend in the sticks used to live until 3 years ago.
**And she had a 70-year-old girlfriend coming to visit the woman's kid and grandkids, and visit my friend too.So she asked her to pick up the board in person, to make sure she had it when she flew over. We met her in Athens, had a nice visit with everyone (I didn't know them before) and then my friend and I went up to the hills/mountains
I put the board in and the TV works perfectly.
Not only are there not many OTA tv signals here, but because of her location, there are probably none. I used a piece of wire about 6" long, which would be enough in a city. I'm looking for a longer piece, but she wasn't upset that she'll have to buy cable. When she gets back from Baltimroe in a month or two, she's going to do that.
