hi there, wondering if I could get some help here:
I have an old CRT tv black and white, I’ve plugged it to an HDMI/composite to RF modulator HDM69

It used to work some time ago but can’t find out why it doesn’t anymore

When I don’t plug anything it seems alright (but not sure it really is) but as soon as I plus HDMI or composite my tv doesn’t display things right
Notice that it works on my modern tv
Here is a video showing what’s happening video

Any ideas ? <3

PS: the horrible noise is my vaccum cleaner

    Unlikely. The interference from the electric motor just worked because analog TVs used to recieve a (weak) analog signal via antenna. That doesn’t apply to the HDMI/RF connector. I suspect the CRT might not be able to deal with the HDMI converter’s line frequency. Also., I don’t know if the CRT has a separate composite input - if you go in via the antenna input be sure to set the converter to RF, not to composite output if possible. Composite and RF signal are not the same.

      That may be right, like I said Im not an expert. But when I was a kid we had a tv that misbehaved when the washing machine was working even when watching through composite.
