Panasonic CT-1310M keeps blowing horizontal output transistor

Found it. 4.7μF, lives near the HOT and is rated for 250V only. If the HOT blows again even with the brightness & screen turned down I will replace it.

This is the screen potentiometer. which side is low/high? I don't wanna risk overloading the HOT with the wrong setting. Resistance is too high to measure with my multimeter.

I resoldered the pads for the FBT, driver transformer, and the HOT leads on the main PCB. I replaced the safety capacitor & HOT. I turned screen & bright all the way down. I did NOT use a lightbulb in place of the +B fuse. I didn't measure +B either. But I did catch the HOT death on camera, sadly. https://youtu.be/3RQW40rBP8s

Here is a frame-by-frame analysis of the HOT breaking down.










I only have one HOT left. One chance to fix everything...
the +B adjustment knob is left on one extremity. so turning it the other way will either decrease +B voltage or send it through the roof.
