Re: Video Calibration Q&A

I started to calibrate my tv and I have a question about the "Service Menu", not User Menu, for a Samsung LN32a550 tv. If someone (ME...) has gone into the SM and made some changes to the WB & WB-Movie numbers, can they be reset to the factory defaults if you use the "Factory Reset" setting in the SM? I neglected to write them down before changing and hope to get everything back to the default settings before retrying to calibrate my tv again. If not, where can you locate the factory settings for the SM that came with the tv from the manufacturer?

Thanks for any help.
Bob

Re: Video Calibration Q&A

The only place that might have default settings is the service or training info. I do not recommend a reset in the service manual unless you know what parameters it affects.




Looking for me, just google my username. I have used the same one for most sites for many years.

Re: Video Calibration Q&A

That all makes sense Bill. Thanks. Is my understanding correct though, that some of the affordable colorimeters out there are ok unprofiled, even on LED back/edge lights, for grayscale work, and the profiling is only really necessary for CMS work? I'm talknig about the C5 and DTP94.

Don't worry... nothing new here, I've already made that mistake. Trust me.

Agree with Leonard on this one. Most SM "resets" take the display to a common set of values before any device-specific settings are loaded in the production line. In other words, the reset could be worse than simply working yourself out of the current hole.

Always, always, always write down the values you see in the service menu before making any changes. Also, it is usually worth investing the $20 - $30 for a copy of your TV's service manual before you start poking around. It's not a guarantee, but it should sober you up for how little explanation/information is available should you decide to skip rule #1.

Re: Video Calibration Q&A

Lots of service manuals are available for free if you dig. Virtually all are available for under $20 online. There are suggested sources in the DIY repair stickies and there are vendors in the vendor listings that have manuals.

Re: Video Calibration Q&A

Thanks Bear5K and lcaillo. You are both, of course, correct. I should have been more prepared instead of just jumping in without much thought! I am looking for a service manual here now but unable to locate one that might have all the settings from the factory shipping setup...but, I'll keep looking.

Thanks to both of you.

Re: Video Calibration Q&A

I was hoping that someone might be able to help me. I am a newbie, and have attempted to do a video calibration. I have a Sony KDL52V5100, although it does have controls to do a gray level adjustments, it does not seem to have controls to adjust colors other than the the standard ones found through the remote control (Color & Hue). What is the way to the x,y,Y values for each color? Is this done via the Service Menu? What ever help anyone can give will be appreciated.

Re: Video Calibration Q&A

Hello,

I have a Samsung LCD TV, model LE32B651 and I need to re-calibrate ADC values in the service menu. My concern is that the TV goes into SM under "dynamic" (or "standard") mode and calibrating in that modes seems a little odd to me. The service menu has this "WB Movie" option wich I can enable and rollback to ADC calibration... should I do that? The service manual has no word about it.

Thank you very much for your answer.

Re: Video Calibration Q&A

How often does a Calibrator need to go into a service menu or do they ever? If so; why?
