TV calibration help

I'm hoping someone here can help me with this. Yesterday I found out that Sony Blu-ray's have a hidden calibration tool on them (accessed by pressing 7669 from the main menu). So, I've been trying to use it but there's not any instructions.

 

I found a thread on the blu-ray.com forums about it which helped with the colour bars, but not much else. The tool has 4 screens (colour bars, a white screen with black symbols on it, a screen with a fade from black to white and a black screen with a white 'cross hatch'), the last three of which I have no idea how to use. All I've been able to deduce (from the 2nd screen) is that my Philips 42PF7621D/10 TV is 'overscanning' the image as the 16:9 markers are not visible unless i use the remote to move the image from side to side.

 

Has anyone on here used this? Or does anyone have the same TV as me and can tell me how to sort my overscan problem?

 

Any help is appreciated.

Re: TV calibration help

I would imagine that the overscan settings are in the service menu, if there are no settings available for 1:1 pixel mapping in the main menus.

If you don't know what your doing, I would advise against entering any service menu. 

The test patterns on the BD discs are just a pointer to the levels the disc was mastered at, you can use them sparingly to check a few items but they are not designed for any calibration.

Re: TV calibration help

Thanks for that link. I watched the video and bought the calibration disc they use (DVE: HD Basics) which was pretty useful. Judging by that disc my TV is overscanning by 2.5% which they say is tolerable, so I guess I'll just have to live with it as I can't afford a pro calibration.

I do have one problem though when using that disc and if anyone on here can help I'd be forever grateful.

I own a Philips 42pf7621d/10 LCD telly and on it, when I try to adjust the colour, I can't get it to work properly.



I look through the supplied blue filter and can get the blues pretty
close to how the disc tells me they should look (a uniform blue screen with 6 black squares). I then look through
the red filter and they are just as good. But when I check through the
green filter I can still see every colour on screen - magenta, yellow,
blue, red etc. They just have a slight green tint to them. According to
the disc I should see the same as with the blue and red filters; a uniform screen with black squares in it.



I have Tint set to Normal, Colour Enhancement set to Medium and Dynamic
Contrast also set to Medium, although having tried changing these it
makes no difference.



Has anyone here got the same TV or run into a similar problem and can maybe point me in the right direction for sorting this?



Any help is greatly appreciated.

Nobody has any ideas? Not even anyone from the mag?

Re: TV calibration help

Sorry, only just seen this thread. I know we find Philips sets the hardest to calibrate - it takes far longer to get them looking at their best than most rivals. I'll pass this onto the test team and see if they've any tips on your particularly set-up issues....
