Default Re: Help With Vertical Circuit. Capacitor getting extremely hot

Hi I don't know if this will help but looking at the datasheet for TDA3653B, the vertical drive comes from the horizontal (jungle) chip in the form of a ramp, which if missing will result in the loss of vertical scan. If you have a scope look on pin1 and 3 for a 50Hz ramp. If missing you will need to fault-find the preceding stage. It might be a TDA2578A as these two chips 'go together', but I don't have circuit information on your set so it is something of a guess.
Sorry if I've led you astray.
