Hi @gmchoi96
Can you please verify if the LCB ribbon cable is securely connected? Its loops underneath the PCB.

Hi
I checked LCB ribbon cable and it does not work even though I disconnected the cable and put it back in
it does not work

Thanks @SangHyun-94
I'll process an RMA for a replacement LCD. I have an existing support email with ROAS that I will reply to.
