HDMI problems

I have an LG 42LF7700 TV. It's about 5 years old, and has been trouble free until now.
It has 3 HDMI slots on the back, and for the past couple of years these have been connected to a Blu-Ray player, a Chromecast and a PC which we use to watch Netflix and stuff. Everything was working perfectly until last night.
I tried to watch a DVD but the TV couldn't connect to the Blu-ray. It now comes up with a "No Signal" message. After checking all the connections round the back, I checked if the other devices were working. The Chromecast similarly won't connect, it shows the same message. The PC, however, is still working fine.
I know it isn't the ports on the TV as if I unplug the PC from HDMI3 and put it into HDMI1 or HDMI2, it works perfectly. Similarly, plugging the Blu-ray or Chromecast into HDMI3 brings up the same No Signal fault.
I'm at my wits end. I have now reset both the Blu-ray and the TV to factory settings, which made no difference. I have also swapped the HDMI cables around and it isn't the cables (the Chromecast doesn't even have one).
I know it isn't any sort of update as neither the TV nor the Blu-ray can access the internet, and besides both have been reset to factory settings. If it were either device, I would put it down to them dying, but it seems very unlikely to me that two devices would fail at the same time.
Does anyone have any ideas what the problem could be?

Tried the Bluray/Chromecast in another hdmi display? Like a computer monitor?0

So, other devices on the same cable into the same HDMI port work fine.
And the devices themselves work fine on the same cables into other displays?
Scrambled settings? No power from the TV's USB for the Chromecast?0
