Tv cherps when you turn it on

hi,

have a voltage check on the power supply it might not have enough, to power up the horizontal deflection circuits.

maybe the supply rail B+ is only about 45V or still lower
solution : replace the horizontal deflection flyback transformer maybe partially shorted

maybe no voltage at all
solution : check horizontal output transistor might be defective, replace if found shorted

maybe there is a good supply say at least 110V , but no oscillator drive on the horizontal output transistor, or blocked oscillator signal drive

hope this helps, thanks for using Fixya!
