My smart lg 55 inch both hdmi2, 3 just stopped, tried what ever is plugged into hdmi1 on both 2,3 but they does not recognise it and says no signal. at the time when they stopped working a ps4 was plugged in, but the PS4 works fine on HDMI 1 without any issues. don't understand. i would appreciate some advice.
It's possible for some HDMI inputs to stop working.
You can use an external HDMI input selector.
You can try replacing the HDMI board (if there is one). www.shopjimmy.com sells replacement boards and are very helpful.
Thanks for your reply, i have the HDMI extension but its painful have to keep getting changing the HDMI switch every time i wanted to switch between the freeview,ps4 and amazon fire stick ( world of laziness ). I did take a look at the website you sent me, but it doesnt work. will it be a HDMI board with 3 output? does it have to be LG board?
