Nice ! a few more tips,one much the same.
Sears / Sanyo 19" sets were getting H-K shorts left & right.
They used Sylvania jugs but Sylvania didnt have the problem.
Rewire filament so one side DOSNT go to ground.
Put 1.5 meg between the F & the K of the shorting gun.
Also added a cap .001 IIRC but cant remember where !
Worked good. Also did it to a few other brands. I could tell
when it shorted but it made the TV usable again.
For low E
If the filament comes off the FBT and its an opened core FBT add a
winding or two in series with the filament. Best to use a scope
doing this.
Or you can jump out the low ohms resistor in series with the
filament. Again use a scope to be sure not to over do it.
