1. Make it a warranty issue. If out of warranty consider extending the warranty, don't call it in for the waiting period then call it in.
2. Try the old reset. Unplug ALL connections to the TV. Remove power from the TV for 10 minutes, then apply power and one connection, test.
Hi My LG 55LV5500 TV worked fine until last week. When turned on, it won’t response for some time.
Then when check input, most the options were grey (including all HDMI, Component and Composite; all are connected well). When I choose any HDMI input, no matter I choose 1, 2, 3 or 4, it only picks up signal from HMDI 2.
Also, there’s no sound.
Any help is deeply appreciated!
