First, thank you for all the help provided on this topic. I too make the mistake of doing a calibration on the Service Menu without some proper research first. If you are near panicking like I was, relax for a few minutes, you can Undo what was done ;)
I'm writing this post so that it might be of some help to some of you, like all his topic is already. Sorry if it's a bit messy.
Model: UN32F5500 (32" Led Smart TV)
- What I did wrong: Went to the Service Menu, executed the AV Calibration. After that, the colors on the RF and AV Channels were all messes up. HDMI and Component channels were OK.
- What I did while in "panic mode", trying to fix the problem: Done a Factory Reset on the Service Menu. (Don't to it, it will not fix the calibration issue!)
- What I did to fix the problem:
- By following this Wiki: http://wiki.samygo.tv/index.php5/Calibration ,I downloaded this picture: http://wiki.samygo.tv/index.php5/File:BW-Cubes.png to a USB stick formatted as Fat32.
- I connected my Ps3 to the AV interface of the TV, using the standard cable that came with it.
- Turned to the AV Channel on the TV.
- Opened the picture on the Ps3 with the stock PS3 Image Browser.
- When to the Service Menu and did a AV Calibration, a "Success" message appeared. The images on the AV and RF channels were now normal :D
Now, this wasn't to me so easy as I said just now, I came across some "issues" that I managed to resolve. I think that describing them can help some of you guys that come across them.
- Problem: Tried to use a JPG image with the Image Browser on the Xbox360 with the standard AV cable. The calibration at first was a success, but the image was still no good.
- Cause and solution:
- A JPG image might be compressed and by that might loose some quality, even if it's only black and white. The calibration expects a full white (255,255,255) and a full black (0,0,0) on the four spots that the pink square uses while calibrating. If the TV finds different kind if whites/blacks while calibrating, it can finish successfully but it will not be proper calibrated. That said, I recommend using a Hi Quality PNG or a BMP image for the calibration.
- Some equipments (the Xbox on my case) might transform somehow the image sent to the TV, which can result in bad calibrations. I succeeded with a Pal PS3 but had some issues with my PAL Xbox360. Might have been the cable or some setting on the console. That said, try another type of AV equipment if you are not reaching good results.
- Problem: Even with a PNG image on a PS3, the AV calibration failed every time.
- Cause and solution:
- At some cases, the values used by the TV can be so way off that even the calibration couldn't find the right values. Lucky for me, the answer was on the Wiki. On the option below of the automatic calibration ( "ADC/WB -> ADC Results" ), you can see and modify the values. Somehow, the second value was by now 0, this was making the calibration fail. I just changed it to 150 and after that the calibration was a success! You just need to check the first two values, change them if your calibration keeps failing, change them by about 100 and retry. For reference, I used the values 450 and 150, respectively.
I really hope that this can help someone. Just two quick notes to finish:
I saw on this topic, the user Talachas said (in spanish) that you don't even need an external image to calibrate the TV. That the TV itself is able to display the images needed to calibrate. This is done by the option VC -> Test Pattern -> Pattern Sel. After selecting the Black and White Pattern, it will disappear, don't worry, it's selected as you can see on the menu.
While still on the Service Menu, go to the channel that needs calibration and execute it. I guess that even while it's not showing it remains on the background maybe, and it's used on the calibration.
This really needs some testing and might be totally false. Kudos to Talachas if indeed it works like he says :)
On my case, it was only the AV that needed calibration. This information can be also used on the other calibrations, you just need to be connected to the proper channel while calibrating. (HDMI, Component or PC)
