Sometimes it might not be the HDMI cable causing the issues, but the LG TV or external speakers. Repairing a HDMI port costs between $100 and $300, whereas replacement will cost around $200-$350. If the sound works, this means the other HDMI port is faulty (unless the cable was not plugged in correctly). If the HDMI cable is fine, try plugging that cable into a different HDMI port in your LG TV. You can find a popular and inexpensive 6ft HDMI cable on Amazon. If your external device is always close to your TV, such as in the TV cabinet, a 6ft cable should be fine. You can generally find HDMI cables for under $20, depending on the length you require. If it’s still not working, it is likely that the cable is broken and needs to be replaced. If you want to test this, try using the same cable with a different TV.
