Facing TV Problems? Ask a TV Technician.
Hi , I`m Jack Perhaps I can help you with this problem , please send me a reply when you see this ?
First thing to try is a reboot .
Unplug the power cord 5 minutes from both unit and this time while they are unplugged , disconnect and reconnect the cables/plugs one at a time securely
Let me know how that goes , i can`t promise a fix with that but it is often all that is needed
