Bad flyback transformer, freewheel diode, snubber capacitor, horizontal output transistor. If you replace one, replace them all. Also could be problems in the secondary power supply, these units use the flyback transformer to feed the audio and vertical sections.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
