I have such a problem.
I was doing renovation in the apartment, I put plaster imitation brick on the wall under it, I made a conduit and let the power cable into the TV socket and the cable into the HDMI socket. Now the following things are happening. If only the light is on, it's ok. However, when I turn on the bathroom light (led) it causes some interference and turns off the image for 2 seconds. This is still to be overcome. When I turn on the electric oven in the kitchen, the picture disappears from time to time, an inscription appears like "your tv has no copy protection press reset or ............. HDCP problem" Reading about cables in the net HDMI write that for short distances a cable for PLN 20 and PLN 100 does not make a difference, but no one wrote to put them away from the power supply. I have a 5m braided cable, not in rubber insulation. Unfortunately, I do not have its packaging and parameters, there is quite a thick shield, it certainly has some. I can't separate it now, and that's not why I let the conduit in the wall hang so that the cables hung from the TV to the decoder.
Now my question is, can you do something about it, put on some anti-jammer for electrical installations or replace the hdmi cable? If you replace the cable for what it has very good shielding.
