Question about Mitsubishi Televison & Video
there might be circuit failure inside your TV systems,first we check on the power supply output voltages, it may not have enough to power up the horizontal deflection circuits.
here is a guide for you.
if you have a multimeter measure the voltage on the capacitor after the diode of chopper secondary windings.that would be the B+.
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!
