Problems with HDMI communications with Cable Box

Ok guys, I've searched and found similar problems, but not my specific problem. And I found no solutions. Sorry if I didn't search well enough and missed it.

I have the following:

TV - Sony KDS-60A2020

STB - Motorola DCH3416

They are connected via HDMI. Normally they work perfectly. But sporadically the connection gets messed up somewhere. The box will try to output in 480p and the TV will flash a display resolution error, then go blank. There will be no sound. As I said, this appears to be entirely random - it may happen several times a week, or not at all for months.

I know how to change the settings on the STB, and that will occasionally work, but most times as soon as I turn the TV on or change it to the HDMI output, it will override my manual settings. The default settings when I reset the box are 1080i and 16:9, so there is something somewhere telling the box to display in 480p?

Comcast and Sony have not been helpful. I have experiencesd this issue with 3 3416's (I exchanged it once because of this issue. I got also got a new bow when I moved). The last time I called my local Comcast, they said they have no other DVR HD models in my area. I'm stumped. It sucks, because when I can't fix the issue, I'm forced to watch via RF bypass.

If anyone can solve this issue I would be indescribably grateful.

Many of us have solved this problem by using the red/green/blue component cables instead of HDMI. They are fine for cable boxes to tvs as the max. resolution on cable is 1080i and component carries 1080i. Your pic will look as good once you calibrate your tv for component and you will have no more handshake issues.

Sweet. I assume there is no need for digital audio output until I get a receiver/multi channel speakers correct?

Yes. I use an optical cable straight from the cable box into my receiver for surround sound. But if you are using the tv's sound, just use red/white audio cables from the cable box into your tv till you get to the external sound system.
