Can I jump in - I have the T7 - was working fine but I think I forgot to discharge a capacitor. Tried to turn on the tester today and it is dead - led comes on if I plugin the usb.

I've open it up and I get open circuit on c3, c25, c9 and r15 - is that my issue?

I have this model (taken from page 11)



Thanks in advance.

as on page 11   looks like same as one  @madires   said has a LGT8F328 MCU  I have the same board, but still working, I never tried dumping the firmware, most likely useless to try as they seem to lock them from dumping.
