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? Rono.
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.
