20" M # WTV-61904, turn it on, hear audio,
but shuts right down! Has high voltage! All checks
out fine, unhook yoke & works fine! Load yoke back
on, & set works fine, now works ok with yoke! Ideas?

Why would you power the set with the yoke disconnected? Trying to burn
a dot in the center of the CRT?
If the set works OK after disconecting then reconnecting a large plug
like the yoke, the problem is likely loose or cracked solder joints or
maybe a hairline crack in the circuit board.
