Bafang C240 display wont turn on

[Filminator]

I've check all connections, battery, and controller, and nothing seem wrong, when I go to turn on the display nothing happens.

I was riding one day and went to take a break on a hill and the buke went into its usual shut off after 5 minutes of no action, and when I went to turn it back on nothing happened.

re check cable connection from motor to display. push a litle bit harder. usually not firmly connected to display.

I'm having the same problem - did you ever find a solution??

I have experienced exact same symptom as the OP (who seems to have come and gone). Out for an easy dry ride, battery at 80%+, stopped for 5 minutes to look at the view. Bike wouldn't switch back on :-(
I have checked all connections are clean and tight (everything looked clean before I started anyway). Battery contacts clean. I removed the bash plate, crank and side cover and checked all motor connections are clean and good.
I confirmed there is 48V getting to the C240.CAN display (green connector). The power switch is grounding when I press it (pins 1~2 on the purple 6 way connector). I am wondering if the C240 controller itself has died?

Did you resolve this issue? I too have a bike which was working no problems and now will not power up display using the DP240

Replace the main cable may help.

Hello Riders,
Since we are the topic of DPC/HMI went to sleep mode and when power on is press on the switch, it doesn't turn-on.
Has anyone use a power-bank to power-on thru the DPC/HMI USB port? I do use the DPC/HMI USB port to charge my phone from time to time but has not use the reverse way to "power-on" the motor thru the USB port. The Specialized TCU has this useful function thou. Thank you for reading.

I had a similar problem I have the cef50 with the power button on the frame. I went through and checked all the cables and still had the same issue. I got it to start working again but now when I hit the power button on the frame I immediately need to hit the power on the display, if I wait more than 3 or 4 seconds it just won't turn on and I have to to turn the frame power button off and on again. Not sure if this helps but worth a try maybe.

Hello friend,
I bypass the power on/off button on the frame so only the display HMI on/off button.

A very late update... in my case it was a faulty controller PCB. I took my bike to the dealer (under warranty). He suspected the switch or cables but was surprised when it was eventually traced to the controller PCB. Apparently the first he has needed to replace from 100s of bikes sold.
