High pitch ring

[tvcollector]

Here are some pictures.. It looks close to the mid 1980s Sylvania Super sets, I'm guessing an early NAP.. The flyback is mounted on the Board.. Does this hold voltage after being unplugged or is it only the picture tube?

those are very good performers!solder joints around flyback or loose core.that will fix it up.sharp,sharp. black matrix crts produce a fine picture.among the best picture of all time
