If EDID is indeed wrong, then what you can do is this:
1. Once you get a good picture, capture the current mode with
and put it in as a modeline in xorg.conf
2. Put the correct HorizSync and VertRefresh in xorg.conf (either get it
from the manual or if EDID is at least partially/sometimes correct, add
Option "ModeDebug" "true"
to xorg.conf and read from the log file when X starts correctly)
3. Disable EDID completely
Then this should work as long as you don't change your TV. And the TV
won't even have to be on before X starts.
