I used Avia on my new 65909 last night and found that the red is +25. In order to drop the red with the user settings, I lose quite a bit of green and blue. If I can find a ISF technician a couple of months from now (after the 150 or so hours), I may get them to recalibrate. However, for now, I'd like to just reduce the red. I've read about a homemade attenuator that has 30 and 390 ohm resistors. Another poster stated this was the equivalent to a 3dB attenuator. Is this correct? I can not find the directions on making one so I thought I would just buy a commercially available 3dB if it is the same. Also, another thread states that the attentuator does not fix the red push when using the HD 1080i input. Is this correct? I have the Hughes E86 set to 1080 resolution in the 1080i input and a progressive DVD player in the Component 1 input. Thanks for any help.
