So my TZ upper gumball flasher is stuck on. This one connects to the 8 driver board A-16100. If I remove the ribbon cable connected to the 8 driver board, the flasher goes off.
Any tips would be appreciated. Could the 8 driver board be toast? The ribbon cable makes me wonder..
Quoted from Pin_Guy:This is an easy fix, and is most likely the TIP102. You can find out which one is bad very easily by buzzing the the J4 conectors to ground, the only one that should have a path to ground is pin7.
If you need help with the board repair, please feel free to PM me.
Thanks. Only pin 7 is buzzing on J4.
I tested with only connector J4 removed. Should it remain connected?
Quoted from Jenk540i:I assumed he meant flipping both ends of the ribbon connector?
Only flipped one. Noob move?
Quoted from LTG:If all is working now, no.
I like to leave working things alone.
LTG : )
Thanks LTG and everyone for your help!
