Hi,

Try checking B+ coil , may be the coil have shorted .

Happy trying

Through my past experience I mwould remove the solder point at the input power B+ line to primary winding FBT. If the HOT has shorted there will be no power.Straight to the point if you know where the HOT is , you can desolder the middle pin or collector of the HOT transistor. If you desolder the pin which result the power led light turn up. That indicates either FBT or HOT has shorted

Check components related with pots thats adding command ic to pots.If they are ok then change command ic with new one.Before this you can check horizantal hold transistor that is placed on hitsink of eht.small in size and check two small transistor placed near it on pcb.Hope this solution works .If not then i am here
