Samsung/DirecTV HDMI Handshake Problem

My brand new Samsung LN32A550 TV is having problems maintaining an HDMI signal.

I have DirecTV service with a 5LNB Slimline Dish. I have already gone through an H20-100 HD receiver and then an H23-600 HD receiver and three different HDMI cables. And still have the problem. I have experienced the problem using all three HDMI ports on the Samsung.

My sense is that this is a Samsung TV problem and not a DirecTV problem.

Samsung tech support told me today there is no firmware/software upgrade available for this set (strange) and Best Buy acknowledges that there is an HDMI handshake (their term) connection problem with some Samsungs and that the LNXXA550 is one of them.

I can always get the HDMI signal up and running by disconnecting the HD receiver and TV.

I will probably return the set, but I need swivel so that gives me only Samsung and LG to choose from.

Anybody have similar or different experience or any advice?

Try just changing the order they are turned on. Always turn the display on first and make sure the input is set to that HDMI input and THEN turn on the STB. If that solves the problem then i think the problem is with the Dish STB not restarting the handshake process repeatedly and continuously as the HDMI spec calls for.

As far as the swivel feature, you can get a disc to stick any display on that gives this ability if it is really necessary. Or you can just use component connections as a work around.

thanks PFC5 . . . all good points.

Another poster on AVS also suggested turning the TV on first. I will give that a try.

I've tried the disc (as a swivel) but in my application (wires / power etc) it does not work well.

I do have Component Video but much prefer HDMI PQ.

A top tech from DirecTV is coming out today. I'll post the results.

I would say if the problem goes away when the TV is on with the correct input first, then it is likely the STB that is the issue.

Also remember that your display has separate memory settings for each input so you need to adjust the setting for the component input you try before you can compare the two types of inputs PQ. I have found with my 4 HDTVs that once the picture is adjusted for each input they are virtually identical, so besure to adjust each input individually for the best PQ since the settings may not be the same for the component vs the HDMI connection. ;)

Good luck and please let us know how you make out with DTV.
