A long shot - add `over_voltage=2` to config on a bad pi. Any improvement?

@yullaw I've had difficulty reproducing this. Can you post your edid? ``` base64 /sys/devices/platform/gpu/drm/card1/card1-HDMI-A-1/edid ``` Can you reproduce issue without hdmi attached? Assuming, say your monitor defaults to 1920x1080@60 when...

Did you test with latest firmware, `video=HDMI-A-1:1920x1080@60D` and hdmi cable unplugged? I assume you can test whether it is happy or not by ssh-ing in and checking dmesg.

I would say that is working. Plug in hdmi at this point - do you get an image? Now reboot and ssh in and run dmesg. Are there errors?

In the last case does unplugging and replugging hdmi have any effect? Not seeing much difference in demsg for working vs not working. I'd like you to get the failing...

When you captured dmesg_4.txt, that was with hdmi unplugged? Was screen blank when plugged in? Did picture appear with either subsequent unplug/replug or change of HDMI source? > If I...

> Copied edid firmware files into /lib/firmware did you do this when display was working (directly connected to TV without AVR)?

Does edid look correct? e.g. compare `md5sum /sys/devices/platform/soc/soc\:gpu/drm/card0/card0-HDMI-A-1/edid` when you are booted with no display (AVR connected) and `video=HDMI-A-1:1280x1024@60D` and `drm.edid_firmware=edid.dat`. And then run again with the config.txt lines removed...

If you have `drm.edid_firmware=AVRedid.dat` specified then you should see the same edid whatever you are connected to (the contents of the AVRedid.dat file). If you are seeing different edid's, then...
