Just a quick update - I replaced the display and it appears to be working fine. Now I need to go hook up the brake and speed sensors. Are the magnetic brake sensors for hydraulic brakes just one big closed circuit that opens when a lever is pulled (wired in series)? Or are they an open circuit...

Good thought - I disconnected the orange (LCD) and red (motor) leads from each other, and joined the red (motor) end to the brown (LCD)/blue (motor) cable join. I left the now free orange (LCD) lead disconnected. I still need to hold the power button down (so it does not progress to the next...

Thank you for your reply. The display successfully determines the firmware version of the controller - tx/rx do not appear to be switched. Brake sensors are not currently connected for simplicity - do I need to pull this to +5v or GND for the display/controller to init? Obviously the 850C does...

Not that I am aware of - I'm usually pretty good with paranoid checking of everything prior to applying any power - but of course, anything is possible. If you've seen the same symptoms, I will assume I require a new display.

Thank you for your reply. Do you know what component within that may be, so I can determine a testing procedure? I assume a transistor somewhere, hopefully user-replaceable but probably within an IC somewhere... I haven't yet cracked the casing, but that's probably the next step. I have triple...

I'm far from an expert here, but yeah that probably fried something. Old-school serial would sometimes be 12 or 15V, but pretty sure almost everything these days is 3.3V or 5V. My display doesn't turn on unless I hold down the power button (I think that's a separate issue), if you apply power...

Happy New Year! I've been reading this forum for quite a while, first time poster though - holidays have given me the opportunity to dive in and replace the LCD (now 850C) and firmware on my TSDZ2. I can't seem to get the 850C LCD to power on without holding down the power button. Am I doing...
