I think you need to give more detail about what system your have; motor, controller, etc.

John you need to keep just one thread going as you now have 2 other threads on the same problem and replies to your issue.

I have tried to help as much as I can so far with your issues but without the bike in front of me it is hard to see or test what may be wrong.
Originally we sorted out the lcd issue as a non working faulty/blown controller and had the throttle working with a controller change. The old PAS you had only worked intermittently.
It is possible that now you have new controller some parameter settings might need changing for it to work or its a directional PAS to which there may be four combinations to fitting.

Visited John/Grumpy today to try and sort out his Brommy pas issue, in the end I ended up getting another bike working as well, for the very short term (today only) they both work after some head scratching.

Issue one was the Brommy Pas not working. Issue two he had fried the controller he brought to me he managed to smoke it by connecting up a pair of 18v 5ah Dewalts in parallel (no problems there) but then hooked them up getting polarity wrong so puff goes the controller.
I changed the batteries connectors so that they matched his others (all XT90) , so now all his batts are interchangeable and not possible to get polarity wrong.
For the fried controller he got a UK KT replacement for £25 which I did think was a bit cheap but he wasn't able to get it to work, so rather then mess about my unused Yose/Julet one was connected. The PAS was sorted first by using my V12L for testing then I realised his mag disc was on wrong and the PAS worked peddling backwards so left John with the task of flipping the disc.
He has a 36v 6 fet KT Julet one on order so this will eventually be fitted to the Brommy which I now know does work properly.

The replacement UK controller he got I didn't pay much attention too it until we tried to get it to work on his 700c, after a bit of head scratching and later a proper look on line at the one he bought it twigged that he had got the wrong one. The 36 250w 7/14a KT was a speed controller and had no PAS function.
So I whipped the temporary set up Yose one off the Brommy and set up the 700c and all was easy to sort out and get the PAS working with the V12L.

I sold the Yose KT with a 4-1 Julet to John for the 700c. I gave him an unused lcd1 with Julet in exchange for his Lcd1 with SM, he had my 9 pin /Julet motor lead in exchange for a pair of 9 pin motor leads with the J7061 hall connectors and separate phase wire leads. The V12L wasn't needed as he has one on order.

In jest I did say I didn't want to see him again but am sure I might do or at least he will probably PM me if he still has any connection issues, though it should be plain sailing with Julets. One thing I did say to him is to stop Bloody chopping connectors off as he gets in a pickle soldering them up again correctly, it is so much easier to buy the correct fitting in the first place.
