Well you know... 3 days for a service call in my opinion is too long specially since I already know the equipment will be changed out..
I am hooked up component, but going back to the TV, it's an LG 42" plasma, with three HDMI inputs, I have tried a known working HR24 on it, it works fine. reversely that "bad" HR24 does not work with HDMI on my 52" Hitachi in the livingroom
I unplugged both TV and receiver, used different HDMI cables, tried the receiver on different hdmi ports, upgraded the HR24 software. All the ports on the tv work fine with an Xbox360, Playstation 3 and Blu-Ray player.
Like I said before, I'm good, got the tv going, patiently waiting on the good ole tech !
