Reply To: [STILL AT IT] Think I fried it. Heard a sizzle.

I’m out of ideas folks. Checked the above signals with a scope and they are similar.

Changed out the HDMI chip – doesn’t seem to make a difference. Exact same problem. I connected a HDMI Tester and everything shows normal with the HDMI signal. (5 orange lights for RX, 3 green lights for data, Red for HPD and Green for CEC). That tester only does basic continuty, but at least it shows the connection is good.

On several TV’s and monitors, “No Signal”, and No test pattern.
I also connected a HDMI to DVI cable to a monitor with DVI-In – “No Signal”, and No test pattern.

With a Neo-Geo connected – on AV1 i get

AVI: RGBS 264p
15.73kHz 59.59Hz

I’m giving up.

Here is my debug log in case it helps the next person.
