I own a 65831.

I've noticed lately that when white letters are shown against a black screen, the black becomes "lighter."

In other words, I don't see pure white against pure black.

The whiteness of white text or a white image spills over into the black background making it a very light black.

I've also noticed whiteness spill over when watching images from DVDs and Dish.

For example, someone's white shirt will create a spilling over of white into all adjacent surroundings and objects.

It is extremely annoying and quiet honestly ruins the otherwise amazing picture quality of the 65831.

I've only started to see this recently which makes me believe this has occured within the past few weeks.

Could this be due to poor calibration?

As of right now, I have the contrast and brightness both set to 31.

Any ideas on what is occuring or how to fix it?

Any help would be greatly appreciated.

I reported on this as well (a page or 2 back) with my 731. I received no response as to whether or not this is normal.

I currently set my box to "Fixed" and all signals are sent 1080i. I think the picture looks great but I would like to be able compare the 1080i and 720p.

Thanks,

Joe, I am sorry, I know nothing about that box. I only have the 8300. Sorry. On the 8300 you hit the settings button on the remote twice, then go down to video output, and it is there. I will just post a pic tonight. But I do not know about your box.

Try it with all of the image "enhancers" set to off, including the deep field imager and sharp edge. Also set video mode to natural. Then report back. That way we have a base line of where your set is. I would think turning off deep field imager would help, as will setting to natural if you have not done so already.

uh oh

I think i may have a problem with my 65731.... I just had it delivered from Amazon yesterday...

When I setup my STB (sa 8000HD) to use 1080i everthing is crystal clear. But then I go to DVD and watch a movie in 480i and everything is clear... However when I go back to digital cable, the TV resets to 480i standard. I dont get it

Here is a fast diagram of how its hooked up:

STB>>(using DVI/optic)>>Onkyo 674>>>(HDMI)>>>TV

Also, when I first turned the TV on, the "setup" wizzard came up... Yea.... I don't know what I did, but I think I may have exited out of it on accident, and I don't know how to get that back again. I have already tried the 2 different system restarts and I still can't get that screen to come back up

The TV is actually not changing to 480i, it always upconverts to 1080P, but it reports what the source is, on it's screen.
I suspect that your AVR is the culprit, and once it's on a 480i source (your dvd player) it (for some reason) remains on that as it's output that is sent on to the Mits via it's HDMI.
In any case, the Mits is not switching to 480i, it's just reporting the source is at 480i.
Next time it happens, turn off the AVR, then back on after a 10 or so second wait, and see if it the Mits still see's a 480i source.
If it does then try using the component video/optic from the STB (if possible) to your AVR.

I already had the image enhancers turned off and video mode set to natural.

Could it be the lamp?

Have you tried temporarily turning the shutter off?

That is an advanced but probably helpful idea.

Verified by my tech: The problem is the lenticular and franel screen have come seperated and pushes out which is causing the reflection.

This is weird: it seems that the washed-out picture gradually occurs over a few hours.

When I first turn on the 65831 the picture is perfect.

2, maybe 3, hours later the whites and other bright colors begin to wash out considerably.

I notice some of this on my set, but maybe not to that extent.

I did actuactlly see it a lot on the Simpsons last nitght, a yellow halo. I kinda assumed it was mostly from my poor cable feed.

I will check out more tonight and see what happens.

What are your user menu picture settings? Maybe that could shed some light on the topic (no pun intended).

Bingo! that is the exact problem. the lenticular and the franel are held together with clips. if the clips breaks or slips they bow out from one another. which causes a internal reflection. However my tv also has a bad light engine. Will know 100% for sure wednesday what the fix will be. I am relieved to know that if my light engine needs replaced my isf service menu changes are saved in two places, the dmd board and the light engine itself, so my isf calibration is safe.

PerfectColor/PerferctTint settings for high color temps

All of the PC/PT settings I've read on this thread are for the Low color temperatures. Since I prefer the "cooler" look of the High color temps can anyone give me their calibrated numbers.

From the previous post by lcailio, I have decreased the GBH settings from 1024 to 944 (a decrease of 80 points). Anyone else calibrated using high temperature as the base?

Well guess I need to make another call to Mitsubishi. This makes me pause however and ask myself if buying a DLP was the right thing to do. I have 3 other HD's. One a 34" CRT and the other two are 17" LCD. There have been no issues with any of them. Whereas the Mits thus far is a constant battle. Right now I am wary about long term stability and reliability. Although a little more costly, I could have lived with a 50" LCD or Plasma. I understand that all technologies have their limitations and quirks, but in 5 years will this set be a total POS??

--------------------------------------------------------------------------------

I just typed for one hour regarding this TV and calibration. Needless to say, I accidently clicked to another page and lost it all. Here's the short version.

Latest software for this TV is 8.02. Here's the instructions on how to update it.

My settings after "interpolating" others' settings with factory settings similar to mine are before/after:

6. GGL 998/915
7. GRL 1024/957
8. GBL 805/915

It is better than it was, but the blues are a little punchy for me (I have seen others refer to this as "smurf like"). I will await more posts on this site to make further adjustments. These setting are with the following user settings...

Picture Mode: Natural

Color Temperature: Low
Brightness: 31
Contrast: 24
Color: 46
Tint: 30
Video Noise: Off
Perfect Color: Factory Defaults

These were made with Avia Tuneup disc and Monster/ISF HDTV Tuneup disc. I set color with the blue filter.

These are across all inputs. I will adjust each separately when a suitable test image is available. I will tune in to INHD this Sunday (I had the URL here but they made me take it out...this is my first post) and use theirs for my HDMI connection. The above posted settings are for DVD (duh).

My next step is to get a SpyderTV colorimeter to do this properly. Anyone in the Virginia Beach area wanna let me borrow theirs?

Which brings me to this...does anyone have the service manual for these TVs they can scan and post for us poor people? Yeah, I can get one on EBay for $7.50, but jeez, someone has it.

I will post more about the update procedure (including how to get the update) if anyone is interested.

Consolidation of Service Menu Settings

Here's a quick consolidation of service menu settings for Low mode I've found in these posts. Excuse the username misspellings, as I just glanced at them. These are all for:

GGL
GRL

I will work out the percentages to these later today using the largest value present as 100% and go from there. If the above users who have actually calibrated their TVs using a colorimeter (or equivalent) will let us know that would help.

The only other question is how is Mits adjusting these from the factory. My guess would be some guy with a screwdriver setting a voltage to a certain point for each color, hence the differences we are seeing. Needless to say, I am a novice and am guessing here.

I also had the light engine replaced. Are you operating on the assumption that all light engines are the same, therefore your calibrations are the same?

When mine was replaced, the guy didn't do anything in the service menu, and actually, I am kind of relieved he did not (I wasn't sure if he know what he was doing)!

If you are being told that readjustment is not necessary, than that is good.

Thanks for the work, at least the GRL looks consistent at 1024. One thing I am wondering is if the model makes a difference. I can imagine that it could, and I can think it would not, since the electronics are essentially the same.

Any other thoughts on this?

Service is coming out tomorrow to check my set out. Mits customer service first tried to tell me that this condition was "normal" because of the "high" (read HD ) signals the TV is capable of displaying. That was their position until I called BS. The rep had no technical knowledge what so ever and continually put me on hold while she went to confer with someone else. I will post after the tech shows up tomorrow.

yah my tech is here in the store I work at and he has been fixing mits for 20yrs. He said the service settings are saved in two places the dmd board and the light engine itself has a chip that backs up the dmd board. He said my isf calibration should not be afftected.

OK. So I messed with my SM settings again. I went back and used sourcery's calibrated settings as a baseline. My calculations are as follows:

GGL = 1020 (sourcery calibrated) / 1009 (sourcery factory) = 1.01 x 998 (my factory) = 1008

GRL = 1050 / 1024 = 1.025 x 1024 = 1050

GBL = 915 / 835 = 1.095 x 805 = 882

I adjusted the Perfectcolor to his settings also although I'm not sure this is needed. Then I use my SMPTE color bars to set color via DVD.

Not bad, but really punchy and bright. I found myself squinting watching American Idol. Colors a very accurate though.

This all may be an exercise in futility, but it is fun. What we need are more folks that have had calibrations with before and after numbers so we can compile some data and get some trends set like Icaillo has suggested.

...or we could all go out and get ISF calibrations....
