Is there a special code? I want to try to calibrate it but cannot find these codes.

Why bother? Day mode only needs to be brigher than night mode. It is IMPOSSIBLE to calibrate a day mode because light changes all day and when the light changes, so does the image. Light at 8AM is different than the light at 10 or noon or 3PM. Room light is different than sunlight. Sunlight is different on a clear day and a cloudy day. Sunlight is different when there are leaves on the trees versus when the leaves have fallen. Winter light is different than summer light. Sunlight is different when there is snow on the ground versus green or brown grass. There are so many things that change "light" that it's impossible to calibrate for "day".

All you can do is use test patterns and measurements to see how bright you can make the TV without the color shifting or clipping. Say your night calibration is correct (~35 fL for 100% white) with Contrast set to 50. And you determine the highest setting you can use without having problems in the highlight areas is 84. That means when there is light in the room, you can make the picture as bright as you want it to be and it will still be relatively well calibrated as long as you don't set Contrast higher than 84. If that's not bright enough, you'll just have to set Contrast higher and live with any discolorations that might become visible.

And Mitsubishi Diamond WHAT? DLP RPTV? Laser/DLP RPTV? if so, there is a menu item in the User Menu that you have to enable to get access to custom modes (not available for all models, only the top 2 or 3 models). Mitsu front projectors have different menus but you can't really watch a front projector in the "Day" unless you are using a very directional high-gain screen or enclosed RPTV setup with mirrors and a rear projection screen.

Plus, I understand that isf mode (day night) allows for grayscale adjustments without having to go into the service menu. This is valuable if you are calibrating a set in ADV1 or ADV2 modes.

Does the 837 have the ADV modes? If so that's all you need. Or are you asking for the Mits locking code, or what?

I'm not sure you understood me. If you don't have ADV1 & 2 in the user menu there is nothing you can do. The code I was talking about was to lock/unlock those modes so no one can mess with the settings.

So, why is there another menu for isf (with the isf logo) that is locked?

You never said you HAD and ISF mode, or did I miss something? I'm neither clairvoyant nor in Tampa to look at your display. HT Nutcase indeed. Highlight the mode and then with the remote press 7 4 1 5 3 6 9 enter. You're in!

The 837s support the isf mode but the code you gave didn't do anything.

Btw, I cannot arrow down to that mode until I get the right code.

Considering an email to Gregg Leowen.

The code has never changed that I know of - spells "M" on the remote keyboard.

Where should the cursor be when I'm unlocking it?

I tried it when the advanced mode was highlighted and it didn't work

All the ISF modes do is lock access. The features available in Advanced Mode are essentially the same. Do you really need to have locked down daytime settings?

An 82837 would support ISF modes but why bother with them?

Just another blank signature.

Gregg was nice enough to email me a "reviewers manual" that had the codes and where to input them.

I have heard way too many horror stories and will respect the mods request not to post them here.
