Unit would power on and then shutdown. The set had all startup voltages, HV & yoke drive voltages before shutdown. The set had no coolant leaks on boards. It would show trouble code 23 (no horizontal deflection). Solution: Check all feed-thru holes around IC700 (main micro) and re-do if necessary. Install copper wire on feed thu holes and then resolder connections. Thanks to John@Myers TV for training manual and all members who submitted inputs.
