Also keep in mind there's a lot of 'junk' in the newer video signals that may show up on an older set making you think there's something wrong with your set when it's fine. Mostly the copy protection they put on everything so you don't record it, sell it and retire off all your profits lol. But seriously, there's so much interference that the older sets can pick up that the 'newer' sets filter out, these LED light bulbs, computers, chargers, oh - 'flagging' on VCR tapes, looks like the H sweep is trying to go out of sync. So again, if you see something like that, think outside the box, literally. Also, keep in mind that the newer video format will look like shrunken vertical on an older set, so don't go cranking up the vertical height to try to eliminate it, you'll drain the life out of your output tube and maybe even your output trans.
