Samsung HL56A650C1FXZA HDMI problem

[InuYashaCrusade]

My Samsung HL56A650C1FXZA 56 inch TV's HDMI inputs are no longer working properly. The first HDMI input is hooked up to the cable box which works fine like it always has, the second HDMI input has been dead and useless for roughly 2-3 years and now the third HDMI input has finally gone today.

I've tried hooking up both of my Blu-ray players and my Nintendo Switch and none of the three are being recognized with a simple "no signal" notice. Everything is working fine on other televisions and the cable box works, why are the other two not working?

It's kind of a predicament because the TV can now only be used for cable, which I don't even use... what do you all recommend to fix this? I've tried unplugging everything for 10 minutes and also factory resetting the TV itself. I'm thinking the HDMI inputs are totally fried, it's about 10 years old and is my parents.
