hi,when I turn it on, the Touch Bar lights up blue and then slowly fades out.
I installed it into a donor chassis with a known-working Touch Bar, but the behavior is the same. What could the problem be?
PP3V3_AWAKE_DFR=3.3v
PP1V8_AWAKE_DFR=1.8v
If you connect the Touch Bar after the system has booted up, it works!
