    [HP-NX7300] LCD/VIDEO Issue

    Model: HP Business Notebook NX7300
    Problem: No video on internal LCD

    Strange problem, i tried to hook up external monitor and magic happens, the svga video out work fine.

    Tried also another hp screen+new cable+new panel+new inverter,same problem the lcd panel just bright on for few seconds,then is blank/black,dead, the svga out is fine.

    Maybe a problem to circuitry driving lcd video out?

    It not seems to me a problem related to infamous bga issue.

    Any toughts?

    Thanks

      I suggest you try to reflash the bios. You can do this with a usb on boot or directly from .exe files from HP on windows using that external monitor.

              by Nicktronic
              Hey everybody, got a strange one here.

              The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...

              HP Elitedesk 800 G5 Desktop mini video issue
              by razorhead
              Hello I have a HP elitedesk 800 G5 Desktop mini with a boot issue. I have the lights and fan come on (normal speed), There is no video. I was working fine, posting with initial HP logo before and then it just stopped. Now it just turns on with power LED, fan on, No video and no response to keystrokes. The LEDs on the keyboard also stay off.
              I have attached the main and EC bios dumps here. I have also tried to clean ME and reflashed again, but I am unsure if I did it correctly or not. Attached are the pre-cleaned Bios Dumps. Please help fix this. Thank you very much,

              Model HP...

              Samsung UE65RU7090UXZT main board issue no video out. BN94-14180M
              by alltvrepairs
              Hi,

              I have confirmed that I have a mainboard problem.
              I have tracked no hardware issued on board so might be a software dump required.

              I have searched a bit but wasn't able to find anything for my screen:

              Here are some more details:
              Panel: cy-nn065hgev1h
              Main: BN94-14180M P08F

              Your help much appreciated!

              ​
