Have a few corona boards, at least one of the v2 and a v4 that only beep when buttons are pressed. They are virgin boards. Checked the obvious USB pins, checked U5A1 and U5A2 and the reliability header for proper voltages. I have read that U1B1 can be an issue so I checked that and the voltages do not match up. I replaced the mosfet with one from a working board and still get the same readings. Place the "bad" mosfet on the working board and it works fine. So I have eliminated the fet as an issue. Does anyone have any experience with this issue?

Yes I had problem with corona v2. Sometimes I couldn't start console. And it was getting worse. Later I was happy if I was able to start it. Once I noticed when I used adapter to another console it also couldn't start and glitch chip red led was blinking very weak. So I replaced power brick and it solved my problem. I don't know if it helps you but you can try .

The consoles do not boot at all. With M$ adapter or with aftermarket adapter. But thank you for your reply
