Yeah, that might (probably) wont be an easy switch over unless your original bike brand stocks spares designed for your bike/model.

control systems for eu/uk compliant pedelecs involve a display led/lcd and controller which 'talk' to each other, compliant bikes tend to run modded f/w which can be brand/model specific meaning unless a replacement uses the same coms protocols and specific mods your probably just throwing cash at the issue..

Often the solution to a dead display unit is a replacement display/controller pair.

To confirm if you detail the bike your looking to fix and the exact issue perhaps an alternative solution or confirmation of my suspicions would develop.

Can you snap a pic of the 'control panel' and any lettering on its front and or rear? Also the controller label if present/accessible? Someone with more extensive 'historic' knowledge may have some insight.

My personal interest in all things e-bike is only a few years old so your bike predates that quite a bit.. Google suggests a KT-890-led display when searched(ebike display 980)? If your bike has a standard KT controller there may be alternative display options?? - a pic of the controller label will confirm.

But i think you might be looking at a controller/display pair purchase? costing circa £30 for a basic probably as is controller/display upto £100 for the optimum controller upgrade option.

Again a pic of the current controller and space available would help in suggesting alternatives.

If fitted with a throttle (and legal due to age?) your controller may be prone to a hack that enables it to run without a display with throttle control only but testing could brick the controller too.. considering the difficulty finding a 980 ebike display for sale via google a pinout of its wiring connection could be harder , but tbh i scanned quickly and only one page at that..

The hack is to connect the wires to pins #1 and #2 in the display often coloured red carrying the full battery voltage , and blue 'bike lock' to turn on the controller without a display, Though it will work on many ebike controllers? its a risk? and shorting any logic level inputs to your controller to full battery voltage is going to be deadly to the logic circuitry..

You need to tell us which connector/s it has and how many pins, as there are a few variants.
