I bought new TV and got error 775

[Vanyouss]

Hello everyone,

After many researches I suggested to post my issue on this forum hopfully you guys can help me out.

I just bought a 4K TV (Samsung) once I hooked it up to Directv receiver thru HDMI I get error 775.

If I plug the HDMI cable back to my old TV it works fine!!!!!

I checked all cables and also the SWIM adaptor they're working fine.

What could be the problem here? Please help me.

Thank you

Is the outlet grounded? Can you use audio video cables or does the box have HDMI only ?

It Does have HDMI only. So what I did just now, I plugged in another hdmi cable from the new samsung Tv to the old one and Directv started working.. weird huh!!??

How can I get it grounded?

I was just saying does the outlet for the tv plug into a 3 prong outlet.

The satellite is likely grounded already .

Sometimes I seen a different ground potential between the tv and satellite system.

I had one back in April where the outlet was wired backwards and was causing an issue when plugging in the hdmi cable.
