This display doesn’t have a self test unfortunately but I was wondering if I can’t work out the issue I have this spare display witch the wiring layout is described in the picture but it has one 6 pin connector whereas my one has one 5 pin connector and one separate connector for the blue wire witch does not connect to anything it stays unplugged on my e scooter. Could I use the spare display but solder the old connector onto the spare display matching the colours but leave the blue wire unattached as it’s also 24v same as mine?...

Ok thank you

Thank you, the only issue I have found is the two 101 resistors are measuring at 50 ohms so could that be the issue?

I’ve checked for continuity between the pins and the chip they’re go to and all the pins have continuity but how do I check if the segments are being correctly driven please?

Hello, I have an lcd from an e scooter which works but has missing segments and I was wondering if there is a way of bringing the missing segments back please?...
