A1990 (820-01814-01) not powering on, only 5V on USB
Hi there, I have an A1990 (820-01814-01) not powering on. On all 4 USB ports I only get 5V and around 100 to 200 mA. (yes I know this is not accurate, but I only have one number after the decimal point at the moment) On PPBUS_G3H I get 12.27V What to check next? Thanks in advance- highvoltage
