Yah, I would like to know what the voltages are on that driver transistor....
No need for the scope, the shape on the output looks ok, so no need. q803. Follow the trace to the next component if its more convenient to take a voltage reading. You can measure off the resistor, that 40 ohm, just get the side that goes to the transistor... Same with the base, get it off the r814, one side is ground.... 180 ohms another 5% resistor... That 40 ohm resistor says it should be 5%, but its off by more than 10%..... close to 20% off..... Any discoloring on that resistor.... Was that HV Transformer arcing? did you add that silicone to the HVT? Do you have any idea if the HV to the picture tube is on target, high or low...? If you were to take out the HOT and check the voltage at tp5, does it come back to normal....? Not sure if you have run the set without it in there or not....? Not entirely sure if its safe, I would think it is....
