If the problem is the same the YouTube video.
Maybe the chip (U702) is fault. The model of the chip is EPM240T100C5. And it need to be burned CPLD program.

I worked 5 minutes once, I do not understand anything.

Sir, we can send the software for the EPM240T100C5. But need an expensive tool to program the CPLD software.
You can consult with your seller to return factory for repair or repalce it.

Sorry, sir. I saw the video.

if I put the new one before programming it

We only can suspect that the two components are problematic. The rest can't be judged。
Please try to contact your seller to return factory for repair.
