I got a problem with my h900. Only 2500 heat up when power up, but 1943 stay cold. Do you think what it can be?

Hi Waylene,

Can you post high resolution pic. try to double check your transistor pin by actual test using your multimeter or maybe it could be reverse/faulty diode or capacitor installed, i'm sure the faults is just waiting for you somewhere.
Also try to swap over your IR2117 it could be one of there is dead.
Regards,
