    Sharp MX-M464 Blank Screen

    Good day people.

    Anyone have ever come across this problem? It always happen when I try to replace a new control panel UI, already swap the flat cable, unplugged and connect back the oricon pwb. Even swap the sd card and hdd. Any solution that can assist my problem. Any advice is greatly appreciated. Thanks

    If all your connections are good you need to replace the LCD panel. This is not an unusual problem for this old machine.

      Have you checked input and output voltages on LVDS?

        The LCD panel is actually new. We tested on another machine before we replaced it at customer. Thanks for the feedback.

          I haven't tested it yet. I will try to check though. Thanks.

              The SD card might be corrupted, get a new one to replace it. One of the flat cable pin might have pealed off, in most cases the flat cable pin tips is folded. Replace.
