Possibly (I couldn't get your video to play). Do you have any other HDMI components that you can try with it, like a cable box or a Blu-ray player? You can also try using the optical digital inputs.

I will try with more old thing. I tried with an other computer, same result. I tried with the optical and same result...
 
Is the screeching sound in your video the problem? Not much to go on.

Do all HDMI inputs and outputs have the same problem?

Have you tried doing a reset?

Quick search result.

To reset a Sherwood RD-7505 AV receiver, perform a hard power cycle by disconnecting the unit from the power outlet and all connected devices, leaving it unplugged for at least 30 minutes, and then plugging it back in.
Hard Reset Procedure: Unplug the RD-7505 from the wall outlet and disconnect HDMI/speaker cables to clear memory. Wait 30 minutes before reconnecting power.

HDMI/Signal Issue Reset: If the unit is experiencing issues with sound or picture, power cycling both the receiver and the TV can reset the HDMI handshake

Hi thanks for your time.
Yes the screeching is the problem. All HDMI did the same.
I didnt try to hard reset I will try this.

Is the card responsible for the numeric somethinf that can be changed ? I don't know much but I'm curious to learn about electronics.
 
Yep, that sound is exactly a dead digital/HDMI section on the receiver. Analogue AUX being fine says it all. Still worth keeping for 5.1 analogue use at 100 bucks.
