Everything is OK but Openhat issue... [solved]

Hi there!

Yocto 808 is alive! The Openhat instrument doesn't work... But Closehat is ok...

With my scope, I can find signal on base of Q27, but nothing after. On base and collector of Q30 I find the signal. Maybe Q27 is dead? D13 is ok.

Sorry for my poor english..

Thanks for your answer

Use your multi to test your transistors. If you don't know how, Google it.
