No horizontal drive the 9volts reg. ok the main power supply ok b+ ok i try replace ic801 nothing happen,testing q752 ok all electrolitic capacitor is ok horinzontal drive q601 ok

Obviously a power supply fault I think, you might need a new
LINE OUTPUT TRANSFORMER ( if everything checks out o.k. in the power supply circuitry)

Good day.
Have you cheched on your vertical IC? The zener diode along B+ and try to check zener diodes along the secondary supply form your flyback.

ac supply track check this ic ac pals track on resister 240k or470k &diode check this track
SOURCE: shut off itself
sounds like you might have an auto overvoltage shutdown circuit kicking in. The hivoltage goes to high and the monitoring circuit auto shuts down. More than likely trouble is in hivoltage circuitry. If you have a transformer that will allow you to bring up the set slowly without shutting down and you can look to see what's happening.
