DIYbanter - Sharp TV lost vertical, Questions about vertical output chip?

Sharp model 25A-S100
Vertical output chip NTE7039

In the past TV had intermitant vertical problems, resoldered pins 13,
12 and 11 on NTE7039, good for two years. Now have just horizontal
line acroos screen. No schematic.

Questions
Pin 8 pump-up output, does the chip supply that Voltage or another
circuit?
Pin 2 is this 4.45V over driving the trigger, cause of failure?
Pin 13 Where does this Voltage come from?
I can order a NTE7039 for $10.00.
Just not sure if it's the NTE7039

Thanks for any info
