Check the LVDS cable; the flat cable that connects the LCD screen to T'Con board for any loose contact at its both end sockets. Re-seat it once and check. Gopakumar Gopalan Google

Probably the easiest way is through a jack to jack cable (3.5mm). One end plugs into either the speaker output or headphone output on your laptop and the other plugs into a socket that is most likely on the side of the bar and will be associated with iPhones/iPads - on my sound bar I would use the iMusic setting. Depending on your laptop/sound bar their maybe a number of other ways to connect that may be preferable.

If audio [sound] is OK, and the fault is with only picture, check and replace damaged component/board, at its back-light section circuit. Gopakumar Gopalan Google

This TV will only display photos or play audio, not videos through the USB. Hope this is what you were asking.

Sorry, you can try reconnecting connectors on T-con board (small rectangle board at top center under metal shield)if you are lucky, but it is likely a panel failure. It won't hurt to watch it as it is, if it doesn't bother you

you can remove the fuse and check them with a multimeter. put a lead on each end If the meter shows a low number (normally less than 1), then the fuse should be okay. if not than you need a new power supply board. be sure at all times to have tv un pluged while working on them and always be very cautious as the do still hold power. hope this helps
