Hello there, Justin. Thanks for reaching out about your LG SN4A Sound Bar. We understand you're having an issue with the sound bar's screen after connecting your record player via the USB to RCA cable. It's great that it worked initially, but it seems like there may be a compatibility issue or a setting that needs to be adjusted. To troubleshoot the issue: Disconnect the record player from the USB to RCA cable. Unplug the sound bar from the power source for at least 30 seconds, then plug it back in. This can help reset the unit. Check the display settings: Your sound bar has an LCD display auto-dimmer, which may have caused the screen to appear dim or turn off automatically. Try pressing the Display button on the remote control to adjust or turn the screen back on. If the issue persists and the sound bar is still not functioning properly with other devices, it's best to check the connections and ensure that the record player's output is compatible with the USB to RCA setup, as that could be causing interference. https://www.lg.com/us/sound-bars/lg-sn4a-sound-bar#pdp_specs For additional assistance, you can reach out to @LGUSSupport on social media, and we will help you with more detailed troubleshooting or arrange support if needed. —Renzo
