Do a bit more testing first to see if there is any communication between the display and controller.

You mentioned that your PAS works, so one test would be to determine if the PAS sensitivity changes between 1 and 5.

If it does then the display is transmitting data to the controller. If PAS sensitivity doesn’t change between 1 and 5 then it pretty much confirms that the display is not transmitting or receiving.

You will need to be careful if you buy a new 1t4 because it may come with the same pin configuration that you already have or even a different pin configuration that still doesn’t work.

Also remember that full battery voltage is fed to the display from the controller and if those connections get mixed up then both the display and controller could go kaput.

Limited experience with 1x 1t4 cable supplied with yose kit and a JYT controller although they also supply luishi too? and while waiting for orders to arrive for another bike i used the yose supplied 1t4 cable to test everything was a-ok with no problems again a dual voltage kt controller (17a) and ktlcd-3

One can continuity test the 1t4 on each pin out to rule out cable damage.

The cable must be OK if you can change PAS levels. The battery voltage can be wrongly interpreted if you fit a fully charged 36v battery at first. Also, the P5 setting can delay the display of battery voltage. Make sure it's set to a suitable value..

Sir,thank you!
Actually, I think this is it. The above one is definitely oxygen before they changed to the coloured connectors. This one is probably Oxygen because the colours are in the same sequence as the other one, but there's a chance it's KT. The only difference between the two, is the position of the pedal sensor, which moved to a separate connector direct to the controller instead of going through the main harness:
