Yamaha PSR E403 keyboard came in today presenting as non powering.
Connection to a bench PSU ruled out the external psu as root cause, keyboard was delivered with several wallwarts all labelled as correct voltage /polarity. These will be checked for correct output.
Fault was described by the owner as initially intermittent before complete failure to power on.
Initial visual check finds the top casing is not fully secured allowing unacceptable movement.
Stay tuned 🤔
