Help with HDMI problem

[murderdollsarecooltwo]

I have a multi HDMI adapter and i want to have my Switch, Wii U & PS3 plugged into it and conected to my TV all together BUT while the Switch and Wii U work just fine when i try my PS3 i get a message on screen saying Invalid Input (i think that's what it says) and i don't know why. Is there any way of sorting this out? Thanks.

Most likely a dead HDMI port on the PS3.

Maybe try to hook up the PS3 through component

Start by connecting the PS3 directly to the same input you connected the HDMI input selector.
If it doesn't work try a different HDMI input on the TV. Try a different HDMI cable. If that doesn't help the problem is the PS3.
If it does work then try a different input on the HDMI selector than you used before. Try a different input on the TV.
It could be the input selector.
