Unfortunately, I don't know what to suggest to you. Please double check bus connections.
Hi! Here we have only a display for replace. Touch screen had been organised on some kind of infrared backlight. You can see IR diods and sensors around metal plate. So, I think, it something wrong with bus connection. Check if you made reassemble in correct way.
In my case it has the same quality. I bought it on Aliexpress also.
You may use any double-sided tape you'll find in a shop. I used a 0.5 mm tape or thinner. I found it in a Stationary shop.
