Troubleshooting HDMI Connection

I've been having a bit of trouble connecting my laptop to my TV via HDMI lately.

It was working perfectly for a few years.

A few weeks ago, when I connected my HDMI cable, my laptop screen would go black but the image would not appear on my TV. I tried the same port with the HDMI cable from my blu-ray player and it worked - so I assumed the cable was broken, tossed it, and bought a new one. It arrived about a week ago and I used it a few times.

Fast forward to today, when the same problem comes up with the week-old cable. My laptop screen went black, signifying that it recognized the HDMI, but the picture didn't appear on the screen.

I took the cable to a different television and at first it showed the same problem. I unplugged the cable and changed the display settings on my PC (Windows 8.1) and re-inserted the cable in the TV - it worked! Thinking my problem was fixed, I brought the cable back the the original television - same problem, black screen.

So, again I took the HDMI cable from my Blu-Ray player to use it between my laptop and the original TV and....it worked. So the ports aren't fried on my TV.

I then tested the new-broken HDMI cable to connect my blu-ray player to the same TV. It flashed for a second and then went black.

I'm so confused. It seem like my TV is rejecting certain HDMI cables that have been plugged into my laptop.

In summary:
HDMI Cable #1 DOESN'T work on TV#1 with laptop, but it USED to
HDMI Cable #1 DOES work on TV#2 with laptop
HDMI Cable#2 DOES work on TV#1 with laptop
HDMI Cable #1 DOESN'T work on TV#1 with Blu-Ray player (it flashed for a second, then black)

Additional Information:
I do hot plug HDMI Cable #1, and HDMI Cable #2 never gets plugged/unplugged. But I still can't understand why it would work with one TV and not the other.


I don't want to keep having to buy cables, because I have no idea what is causing the problem. Help?

Not all cables are made equally. Where are you buying them from?
