Mitsubishi WD-xx737 / 837

[Anonymous]

Hey just wanted everyone to know…

The new 2009 DLP models have user accessible ISF modes. The 7 series has 1 and the 8 series has 2. They can be found in the user menu under the “picture +” menu (located next to the perfect color menu).

Upon entering this menu you can select ADV1 or ADV2. All the adjustments you need for calibration will be accessible without the entry of the service menu, except geometry functions. The menu includes a traditional grayscale adjustment, and a CMS that rivals the Samsung CMS.

Once the calibration is completed highlite the ADV1 or ADV2 option under picture mode and enter 7415369 (alittle tricky but you may notice it spells a M… nice). This will lock out that picture made and change it to ISF DAY for ADV1 and ISF Night for ADV2.

attached is the “reviewers guide”

Good luck with these displays. I have found much better results avoiding the ISF modes and natural modes and using the bright mode (seriously!).

here you go

I understand that you are emphatic about calibrating the brilliant and bright modes (as opposed to the ADV modes) as the best practice for these sets…so is there anything we can use the reviewers guide for?

I did one out in Seattle a few weeks back in ADV modes and really did not notice anything out of the ordinary for it not working right.

On a 2010 Mitsubishi DLP, I can see why Gregg recommends working OUTSIDE of the ADV/ISF mode and in other modes, as the fL is very low for daytime use even with Contrast pushed to the max.

However, the SM does not appear to have the WB options documented in other threads. The only options in SERVICE /TVM (at least on the model i worked on)

1.HVPOS (THE HORIZ/VERT POSITION)
2.TSP (NO IDEA)
49.GRWL (maybe Gain Red White Level?)
50.GGWL (maybe Gain Green White Level?)
51.GBWL (maybe Gain Blue White Level?)
61.BCMI1 (NO IDEA)

That’s it…everything…no numbers in between, unless i am missing something somewhere.

If 49-51 are Gain, where’s the other side?

Can anyone shed any light on any of this or any of the missing items?

thanks!

lots of the mits dlps only have gains assuming that is what 49 50 and 51 are.

Did the sets you are referring to in post #2 have adjustments for high and low adjustments?

The particular set I was referring to will only reach roughly 30fL at 100% in Natural, Cinema and ADV/ISF where bright will reach 45fL (and Brilliant is double that), so if one has a bright/non-light controlled room, Normal, Cinema and ADV/ISF could certainly become an issue during the day.

EDIT: Corrected Normal to Natural

[Gregg Loewen]

i think you mean natural and not normal?

Use bright and brllliant and then do what ever gray scale adjustment you can in via the service menu. the Adv / ISF modes have severe gamma and color decoding issues (despite being able to hit Rec 709 on a 75% stimulus window).

ALSO>>>THIS DISCUSSION SHOULD NOT BE IN THIS AREA. This area is Alphabetically sorted so recent posts do not show up at the top. It is only by chance that I saw this thread.

thanks
