I recently started having an issue with the Sony TV blacking out and sometimes losing audio .

My Sony XBR75x850d will lose its video and sometimes the audio. The screen will flash from black then to a good picture.

The screen will display a Direct Tv code 900 and tell me that it's advised that I install component video cables. ( That's not going to happen )

1. Sony XBR75x850d
2. 65 feet of Ethereal CAT6
3. Key Digital Balun KD-CATHD250 Lite set
4. Ethereal MHX-HDME1 2 total 1 meter HDMI cables
5. Direct Tv box

This is a super easy install with no complicated parts. What concerns me is that I have several of these equipment combinations installed. My software updates have been done with Direct Tv and Sony.

And good advice would be appreciated.
