CP5176 FET compressor / Re: Pop sound and some smoke upon testing

Thank you! Could I ask, how should I check that R56 and R57 are ok in the circuit? 

I have followed the setup guidelines. When I use my meter to check voltage on V- (black probe to test point 0V) I get 16 volts but on V+ I get .001volts. Also when I test TP7 I get a zero reading.

CP5176 FET compressor / Pop sound and some smoke upon testing

« on: November 22, 2022, 04:45:43 AM »

I had begun the setup process on my CP5176 and upon plugging the unit into my 500 extension cable, there was a pop and a bit of smoke coming from somewhere around the power transformer. The power button is unresponsive (no green light) and I don't register any voltage when checking the test points as per the instructions.

Hope I did not ruin the whole unit! I think I just need help isolating what could be causing the unit to not turn on or respond, whether it was the pop sound or if I need to just start checking every component from the top. Thank you!
