Question about LG 55UB9500 55" 4K Ultra HD TV with 2160p, 240Hz, WebOS, 3D, LED Plus
Suddenly only HDMI 4 input gets a signal on TV from desktop, HDMI cable should be fine its brand new and now the screen flickers off for about half a second then comes back on about every 30 seconds to a minute minute

If all your other HDMI inputs are out, then I recommend replacing the MAIN PCB
try the following web site: https://www.encompassparts.com/model/ZEN55UB9500UA/_/_/LG/55UB9500UA/55_INCH_UHD_4K_SMART_3D_LED_TV_W_WEBOS
page 4 lists a part number for the MAIN PCB,
HOWEVER, PLEASE MAKE SURE YOU USE YOUR COMPLETE MODEL NUMBER TO ASSURE THE CORRECT PART.

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

I have the 1525 and you have to do extra steps each time you want the HDMI to be recognized by the Bravia - too bad it is not automatic as it is with some. Anyway what you have to do is have the HDMI cable connected from laptop to TV then go to your desktop - right click on an open area (away from icons), a menu will appear, let the cursor hover over Graphics Options - you'll then see Output To...then you'll see Intel Dual Display Clone...hover over that and you'll then see Notebook + Digital Television...left click on that and you should see your desktop on the TV in a few seconds. If it does not work the first time...get your movie or whatever you want to show up and ready and go thru these steps again...stupidly complicated aye? when it should automatically detect and show...are other TVs like this?
