  1. The LG logo flashes when I turn the tv on. Screen is black but there is sound. Roku works with verbal commands, sound but no picture. I cannot see the settings menu at all on the black screen. I have replaced batteries in both roku remote and lg remote. Have disconnected roku from tv and used lg remote to control tv; was able to hear Netflix. Tried the button on the remote for settings, nothing happens. Can’t see settings menu on the tv at all. Getting soooo frustrated with this LG tv! Will NEVER buy another LG TV EVER!!!

    • Try power cycling your lg tv by removing all the power cable and hdmi cables (turn off for 5-10 minutes). If that doesn’t fix the issue, then you need to contact a technician or lg team for help. As this indicates a hardware issue not software.

  3. I have exhausted all the tips given to fix a black screen on my LG tv, what should I do? Is it a hardware problem or it can be fixed using the software?

  4. My tv turns on (led light changes and I can tell the backlights turn on) but won’t display picture or sound. I can’t even get the OSD to show. Is it a bad main board or T-con board, perhaps? I figure if it were the panel, I would get sound but no picture. Any help is appreciated

      • If its the panel, won’t that be expensive? I was under the impression that panels cant be fixed, only replaced. I think I only paid 250 for this TV, and while I don’t want to generate e-waste, it seems pointless to pay the same for the repair as the tv costs. Thanks for all the help you have given me!
