I'm having a problem with occasional blackouts when using an HDMI
connection from my Marantz DV-9500 dvd player to my Panasonic
TH-42PX50U. Along with the blackout, which lasts maybe 3 or 4 seconds,
the audio coming through the HDMI cable into the TV disappears as well
(but not the audio signal to the preamp). The cable is a Belkin "Pure
AV", 16' long. No problems when using a component connection. I'm
trying to decide if the problem is the length of the cable. I
exchanged it for another identical one, and experienced the same
problem. I also wonder if an HDMI extender would be likely to solve
the problem. Any suggestions would be most appreciated.

Follow Ups:
When these "blackouts" occur, what's going on? Are you in the middle of a movie, fast forwarding through the disc, skipping chapters, etc?If it happens when you are doing something other than just watching a movie, it's a polling-handshake problem and I doubt you'll be able to fix it. If it occurs when you're just chillin' and watching a movie, then I would suspect cable length (though that shouldn't be a problem with HDMI at the length you're using due to HDMI's equalization feature) and/or the HDMI T/R chips in the said equipment.
Have you tried another DVD player or source with an HDMI output? If it still happens, it may be the display not getting along with the sources you're using. If they work fine, then I'd suspect the DVD player you're using.
Unfortunately, it really sounds like there is a polling problem (occasional checks due to the handshake protocol for HDMI) with the particular equipment you are using. For many people, HDMI can really be a bitch. The originators/designers should have mandated "signal-lock" for all equipment, but that would have been too logical.
It happens when I'm just watching a DVD. I don't have access to another DVD player with HDMI, but I'm going to connect the HDMI cable to the cable box and see what happens.David
