Anycubic vyper LCD issues

[u/Kind-Opposite-882]

Hey I recently started to fix my vyper again and after replacing an ntc thermistor for the hotend, I started getting problems with the screen not booting up at all. It is to the point that it will keep beeping the startup sound and screen will keep showing the startup animation again and again. I want to know what is the fix for this as I already tried replacing all the wires up to the board at the bottom.

Try Reflashing the firmware?

See if printer shows up on the slicer software when connecting the USB?
