    Panasonic OLED TX-65GZ950E no image

    Hello everyone,

    so I have this problem with this OLED that had a LED blinking issue at first.
    It was blinking twice so it means according to similar service manuals (I cannot find the proper one) EVDD 24V SOS, Panel or TCON Fault.
    Also, the connector from PSU to TCON which supplies 24V was burned (changed it) and saw threads about this topic but didn't relate completely to mine.

    First thing was to tape the signal ERRORDETECTION so it would try to initialize. And it didn't so I unplugged the panel from TCON.
    Then it started up and went to green light and all the voltages are OK.
    Then I realized that the ribbon cable from left side of panel was the one causing the problem so I isolated the signal causing that.
    Right now, that ribbon cable from the panel is shorting a supply called SVDD and I guess there are more problems around there.
    Even though the TV powers on there is no light nor image, I'm not sure about sound.

    Can I try something else or the panel is surely dead?

    Thanks.

      Yes, with all the ribbon cables in but with SVDD isolated from that cable -> green LED but no picture.

        Everything as you said but still no image. Is it bad panel then? Or should I cut the metal case and check the panel PCB?
