Over the past month or so, ever since I ran a hi def signal to my Sony D50, I have been experiencing a strange video drop out while watching an HD movie. I have suspected that I had a setting wrong on the projector that was causing it to sometime lose sync.

On this projector, under the "Input Setting" menu there is one entitled "SYNC SEL". When inputing an HDTV signal the choices are:

1: INT: Set to this position when using the internal sync signal.

2. EXT(C): Set to this position when using the external composite sync signal, and

3. EXT(HV): Set to this position when using the external horizontal/vertical sync signal.

When I originally connected the projector for hi def I selected #3. In thinking about this I suspect that #3 is supposed to be used in conjunction with an external scaler and that my use of it may be causing the video dropout problem I have been experiencing. I am connecting an HD-XA2 and a Samsung BD-1400 to the projector thru a pre/pro using the component connections. Which of the above setting should I be using?

In addition there is also a setting under the same menu entitled V SHIFT. The choices under this setting are:

1: WIDE: Normally, set to this position (factory preset). and

2: NARROW: When some signal such as a superimposed signal with unstable vertical sync signal is input, the picture may be distorted vertically. In this case, set to this position. Adjustable range in the lower direction will become narrow.

Of these two choices which should I be using? As you can tell from these questions I am a noob at all of this and I suspect I have created my own problems with an incorrect setting. Please educate me.

If you have the manual look at page 31 For input A i think you should be using this setting HDTV Yp Bp R. if not try the component one. But I think it should be the hdtv Yp Bp R setting.

Thanks for the input but unfortunately it did not answer my question. I have that setting at hdtv Y, Bp, Br., it is the SYNC SEL setting that I need help with. With the settings you describe I need to know which of the three choices under SYNC SEL should I choose?

Does it have tri color sync? you also hae to see what your reciver uses as a sync, And set your projector to that. also try each player with out the reciever. see what that does Read the specs of each player and use that sync setting it should be int he specs.

Unfortunately I have no idea what you are talking about. My pre/pro, as far as I know is only a pass through switcher. I have never seen any kind of settings on it that pertained to video. I have not seen any sync settings on my players either ( HD-XA2 and Samsung BD-1400). If you are aware of any sync settings on either of those machines please advise.

It has been 4 years since I owned a D50 but I dug this up from my notes from a post from Gatherer for progressive component input:

1. 5bnc off
2. input A
3. HDTV-YPbPr
4. sync Ext(hv)
5. projector needs to start BEFORE the dvd (I tried 4 times)

Also search for posts from KrisRoberts who IIRC provided a lot of tech info on D50

You may want to search the Archive site. A lot of the info was from '01, '02 time frame.

Good Luck!

My G70 setup matches Hoya's recommendations above (though I don't have the #4 option, or it's not relevant on the G70). I also found that my G70 would occassionally not sync if I had selected input A after a valid signal was present, but that switching the PJ to input B and back would almost always sync it up on the first such retry.

Once sync'd, it would never lose sync.

I realize that's not all that helpful since it doesn't tell you anything you aren't already trying, but I would recommend considering another HD source, on the off chance that you have a bad interaction between the source and your D50. (Besides, who can have just one HD source anyway. ;) )

Setup as Hoya has posted the settings
as for sync it auto syncs with these settings such as sync on green
D50 is same as G70 for these settings
may need to turn input off and on a couple of times but once it syncs it locks
in:D {you cannot lock it manually}

I would check again as u do have options 4 under input in menu
4. sync Ext(hv)
otherwise you would not have component

I have read all of the above posts and find them helpful. I suspect, however, that I have not made my problem clear. It is not that I have no picture when first powering up the projector but rather that after a movie has started the picture will drop out for a second or two at seemingly random points during the film. In fact while watching Letters from Iwo Jima it dropped out to the point that the picture did not return. All this when the setting under "Input Setting" has been "EXT(HV).

I did discover something interesting the other day while watching a BD film. The dropouts that occurred while watching that film, of which there were 4 or 5, all occurred at the same points on the DVD and were reproducible 95% of the time.

In trying to isolate this problem I changed the Input Setting to "INT" and then watched a number of movies on both HD DVD and BD without one dropout. The problem with that setting however, is that the pj will not sync on a SD DVD. In order to watch a SD DVD I have to go back in and change the setting to EXT(HV). I have no idea what is going on here perhaps one of you guys do.

How do you do this?

I have used two sources, to wit: HD-XA2 and Samsung BD-1400. While both suffer from this problem the BD-1400 seems to be the worst.

It might be as simple as updating each player with the newest firm ware. Have you done this yet? Not sure what the newest firm ware versions are but look it up in the HDTV forums for HD-DVD and the Blu-ray forums.

Also if the movie doesnt play after the drop outs, try to shut off the Receiver your using as the switching source and turn it back on. Maybe this will re sync it? just a thought.

The first thing I did when I brought both players home was to install the latest firmware. The movie has only failed to play once. The rest of the time it is a momentary drop of signal. On that one occasion I got the picture back by changing the resolution on the player to 720p and restarting the movie at the chapter where the dropout occurred.

I'm not sure that the Sony's can go as low as 480p on component inputs, at least I recall having little luck (and no reason to keep trying). Mine is rock-solid once synced on 720p and 1080i though.

I suspect you need another ifb-12 card to run HD on your players most of us do have 2 x ifb-12
that way you run sd from input A
HD from Input B

they do run 480p

PEH whats your location? You should add it to your profile, sometimes there might be someone in your area that wiould be able to come out and help you.

Yes, that was the conclusion I was coming to. I do have an input B so I may be going that route soon. I have, however, ordered the moome EXT-HD HDMI to component converter with the thought that maybe that unit will solve this problem. Maybe not I guess I will just have to wait and see.

I live in Reno, Nevada. The closest person who might be able to help would most likely be in California someplace. This town has few, if any, people who seem as knowledgeable as you guys.

Good decision the moome crads are excelent.

Do you think the ability to take advantage of the upconversion of SD DVD with the XA2 using the HDMI of the moome unit will solve this problem? BTW I have watched a few more movies using the "INT" choice without one dropout.

It absolutely will solve the problem and it's a great upconverting player.

As for input A vs B, I used input A for component input and was running RGBHV to an input B card in my previous setup. Worked just fine.

How do you do that if you are using only one source?

Oh, I wasn't. I sent component HD to input A from my receiver and/or from my myHD card (depending on the setup I had at the time; for a long time, I only had one component HD source). Everything else in my old theater was sent via RGBHV (including DVD and de-interlaced SDTV signals).

I took that theater apart in May 07 to move to our new house and have since bought a Moome card, an XA2, and a G90, but I don't have anything mounted; just a big random mess in the basement room where I've run a few quick setup experiments but work has been so crazy I can't get more than 2 hours every few weeks to work on that project.
