Most likly, the convergence IC shorted out as they do sometimes, and burnt the B+ resistor for that power source or took out the sweep power supply. The only way to fix this is, your going to need a schematic diagram, and know how to work on solid state electronics. if you dont know how, dont experiment was you can damage the set farther, or damage your self with the HIGH VOLTAGE inside this set. If you are good with electronics, order this IC's.,replace them, then trouble shoot the power supply to see wharee the convergence voltage comes from and start there first. lets know how you made out and Good Luck
