    Good day. I have a problem, the display in my dm800hd has stopped showing, but the remote control works normally, assuming a different display, it works fine. I am asking for help

    In most cases it is a faulty oled display, and in some cases another cause such as a bad soldering of one of the front panel pins, motherboard or display, or a problem with the flat cable.

    But easiest would be if you could check / replace it with a new panel.
    Unfortunately I don't see any offer of this on ebay, and wonder if I still have them somewhere in my repair cave.

    Hello. Thank you for your response. The new panel works. Probably the smd element in the oled panel was damaged

    That's of course also a possibility, quite clever when you could find / solve it because it can often be difficult or not repairable.
    And thanks you for sharing your solution.

    Thanks for your reply. How do I understand the markings of these items? Why is ".9"? Is it a mistake?

    It's related to the smd led positive side circuit, thus this voltage may be high, or low.

    Be aware that it does not has to be caused due a smd part, the oled display self could also no longer works.
    they will eventually stop working.
