Disconnecting J6400 the machine works fine. No Speaker Sound.
Even if I replace this small microphone. Its the same.
Checked J6400. No Shorts.
What is the issue?
Bare Board on bench.
Only J6400 Connected. Stuck at 5v.
Flex disconnected at J6400. Machine is 20V
U6400 is bad. I do not have a donor board of this model. What other model chip will match?
