This is definitely a hardware issue, however it could be any of:
* A problem with the display
* A problem with the cables
* A problem with the Thunderbolt-out from the computer

Start with the easiest/cheapest to check, then move on. Try manipulating the cable when it is connected to see if it exacerbates the issue or, as @Danj said, try a different cable (In case your replacement cable was defective as well). If you have another computer to test with that display, or another display to test with that computer, it would help to rapidly narrow things down.

You don’t need to buy the official cable until you have troubleshot the issue. The official one is just a normal thunderbolt cable with a power-side chain. If you have any other known-good cable, you can test the function with it before buying yet another replacement.

FWIW, I have worked on several thunderbolt displays and I have only encountered 2 issues:
# Broken glass
# Bad cable
Replacement cables can be found in various places, including Amazon: https://www.amazon.com/Odyson-All-One-Replacement-Thunderbolt/dp/B0719KP1GK
