PNxxD550 advanced calibration unlocked!/Calibration Thread - Page 3

Wouldn't it be possible to "change" the unit back to its original model designation (that is, a D550) after you've made the desired changes in the advanced calibration menu? Would the new settings stick? Would the HDMI ports revert to their original configuration? Just wondering...I haven't a clue about these technical matters.

I think I read that every time you go into the service menu it resets all your custom settings. You'd be back at square one. Someone feel free to correct me if I'm wrong.

You can do a factory reset on your tv from the service menu and that will bring it completely back to normal.

There is a guy selling an old DVD player that has HDMI out on it for $20. Would this be a good device to just leave on to activate the other ports? Would it need to stay on 24/7?

I believe that would work not sure if it would need to be on or if it could just be on standby

Yes, you can change it back to D550. If you change it back to D550 all the hdmi ports work as they did from the factory. All the calibration settings revert to factory.


You are correct. Every time I have been in the Service Menu all my calibration settings revert to factory default.


This is not 100% true. There are some settings in the Service Menu that do not revert to factory when you do a factory reset.

For example: I stupidly hit the HDMI calibration under ADC/WB. It messed up my color and contrast pretty bad and it said failure next to HDMI calibration. Factory Reset did nothing to fix it. I found the settings it changed and reverted it to the the original by looking at the pictures here. I finally was able to fix it 100% by displaying the correct 8x8 checker board pattern on my PS3 while connected to HDMI 1 and running the HDMI calibration again. Finally it said success again next to HDMI calibration.

Also the Expert Mode Setting for the extra CAL Day and CAL Night picture modes is persistant even when you factory reset.

Factory reset also resets how many hours you have on your panel. I had over 300 hours when I did it and it reset to hours.

If it resets your hours I wonder if they can test to see if you did that cause if not that could work in your favor when it comes time that a problem happens with the set. Or work against you who knows. And yes I see what you mean about the Cali-day/night. I still have that.

I wonder what else we can do with that service menu to benefit us. Someone should know someone that could tell us what those different things do.

You'll have to send me your settings for gamin. I'd like to see how those turned out. Maybe make assassins creed look even better.

Yeah, I thought that was a bit of a negative for me that it reset my hours. Luckily I happened to check it before I tried the factory reset. Not that big of a deal though.

My firmware version is 2011/03/22_001011 (Purchased in US)

Yeah I wish we could dump the firmware versions as well. It'd be nice to at least have a backup.

I wonder when they will start offering firmware updates for the US versions?

Have you taken a look at any of the Europeon firmwares?

German PS51D550
UK PS51D550 (have to click on firmware link on that page)

I have noticed that the European Samsung sites are designed much better for the consumer/owner. They have more information/specs and less marketing BS.

Yeah, I like the Canadian site as well.

I just came across this thread. I have 59d6500. Is there is benefit for me to make these edits as well?

dear friend eXgo,Thanks a lot for those photo ,but would u care seriously for something...please get urself a better camera with proper focus! Don't get pissed off...i'm saying that bçoz u r making a ton of efforts there & doing a yeomen's service to all & posting pictures whenever u can...but all this efforts & the brilliant picture that the d550 can deliver & more particularly after all the settings unlocked, prove little until u come up with better focussed photos from a proper camera(NOT phone camera).Even if u dont upgrade,borrow one & justify the Excellent work u r doing!..plz take this as a friendly advise!

My order is in and will be here in a week.
I will try to take some before and after pictures.

Have you tested the DLNA and WIFI features?

The US and EU models may have slightly different hardware or "core firmware" because the "Expert" menu is grayed out in the SM, even after you change the model number, so Cal-Day/Night can not be turned on from there.

I wish I could test if the "HDMI trick" works on the EU models as well but it turned out that getting a 1$ DVI->HDMI adapter (I got some as VGA card bundles but I left them in the box and I sold the card with the box...) or a cheap broken device (like a broken VGA) with a HDMI port is harder or at least takes longer than I expected.
