    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.

    Hi Rick, if you will keep an eye on this link you should be able to find 1 or 2 used attenuators for sale fairly quickly. I believe I have also seen them here on the HTF For-Sale forum. They go pretty fast, so act quickly when you see one. You can normally get them used for $25 shipped. They are worth every penny! [​IMG] I can email you contact info for getting them from a ISF tech that makes them just in case you can't find a used one. Radio Shack no longer carries all the parts you need to build them.[​IMG]
    From what I have read, you can't use them on the HD input. My 65809 doesn't appear to have the red push very badly on that input anyway.
    Good luck!
