And you probably already realized this but... don't do anything you don't understand in the service menu as you can do real harm which is not always reversible, at least without getting your TV serviced by Samsung out of warranty (warranty gets voided if you mess up anything in the service menu & there is a service log that should be cleared after doing anything in the service menu). There are many posts in the main thread for this TV about tips for service menu access, clearing the service log, and what not to do.

The most common mistake is not realizing the left and right arrows act as enter keys and modify values for a given parameter. Menu is the back button and up and down are the only true (up/down) selection keys. Source cycles through all active sources.

I only had "Failure" for HDMI calibration, while the other 3 had success. Does that mean that only video sent via HDMI is messed up, while if other sources are used the picture should be fine?

Also, does the 720p chess pattern need to cover the whole screen? If so, what's the best way to do it? The patterns I tried never covered the whole screen and the only way to make them do so was to use the zoom feature on my up-converting dvd player, but then the picture would get cut off at the edges. I don't have PS3, I only have an upconverting DVD player (Samsung 1080p), which I believe can not output 720, but only 1080 and I have a bd player (samsung 1500), which I didn't use because it failed to read cd-r with pictures on it. May be it'd work with dvd, I need to check on supported formats.
If I need a device that up-converts 720p, please let me know. I may have another up-converting player (rca) where I believe could specify the resolution. I didn't try it yet (no remote )
If I need to send 720p signal, is there a deice you'd recommend? I could just go to best buy and pick one up.

Will everything be the way it was after I ran this pattern or will it be very close, but not exactly what it was? yestarday I hocked up an antena to antena input and compared the pic quality to the same channel of HDMI\\cable box input. The difference was hardly noticeable and I can't even say which one was better. Does that mean that my setting for hdmi are almost fixed or does it mean that my setting for antena input are messed up as well? Again, the only "Failure" I had was for HDMI input, not for the other 3. Also, can I compare video in PIP mode or do I have to cycle through sources to do that?

Thanks!

Yes, you only need to recalibrate HDMI, the other connections should still show Success next to them (AV, Component, PC). I believe the pattern must be 16:9 aspect ratio (squares cannot be rectangles) but the 7 by 6 square dimensions suggest there might be black bars to the left and right of the pattern (not really sure though, so check the attached file from the service menu from my above post). 720p seems to important.

Don't worry about any non-HDMI inputs. You only need to fix what you messed up.

Good luck.

I'm just not sure what's important - to keep all 42 squares fully visible and have back bars or to not have black bars, but have parts of outer squares off the screen.

Also, can I assume that after I do this the settings will be exactly what they were before I messed them up or will they become very close but won't be exactly what they were.

Thanks again!

How good the end result is depends on how close your recalibration process is to the one done in the factory. I cannot be sure it will work, but it doesn't hurt to try at this point.

However, zoom2 makes the image larger then the screen area. I attached a few pictures where you can see player settings, the incoming resolution and the all possible screen sizes. Please advise.

P.S. I know I should not have anything on display other then the chessboard when I do calibration (resolution, p.size, pause, etc) . I'll take care of that once I get the issues with the image squared away. Thanks!

Is that something I should do instead of using the chessboard pattern or the two are not related and I still need to use the chessboard pattern to get things right?

Thanks.

Your component settings are exactly the same as mine, but they are different then the ones I've seen on another set (picture posted online). I'll need to check out component settings on another 55b650.

What size is your set?
