I've gotten access to the service menu, and can modify the cuts and gains to try and even out the greyscale. Only problem is, modifying these values seems to have no effect on the actual readings from the colorimeter. I've pushed the red, blue, and green values very high and very low to get some sort of changed response, but the greyscale values do not change.

Does anyone have any actual experience calibrating the Aquos line? Is there a trick to applying the new values. They are saved between sessions, so that appears to be working.

Any help or hints would be greatly appreciated.

OK does the greyscale visually change? It should be obvious if it is working! Need to narrow down what the problem is - it could be sensor usage. You know - take the lens cap off - and plug it in!

It does change while in the service menu, but once you close out of that, it goes back to the previous settings -- only the settings that were altered are saved, and come back up when you re-enter the menu.

It just occurred to me -- I may have been modifying another setting in memory (there are 6 total). I did not go back to check each one.

Does that mean you are not saving the settings in SM before you exit or you saved the wrong ones ?
I would like to do the same greyscale cal on my D5U series sharp (very similar) but don't have any info on getting into or navigating the service menu.
If you could send me a private message with the SM info that would be very helpful.
I will be using a spyderTV with s2pro software upgrade to measure/cal the greyscale !!

Thanks Todd

No, it is saving the changes. They just have no effect on any inputs, or modes (dynamic, standard, theater, etc). The numbers are the new ones when re-entering the service menu. The color balance changes while you make the changes in the service menu, but every change disappears when you exit -- but the numbers ARE saved. Check your PM for the info you requested.

I tried your method of access to SM and it works but I'm not sure how to navigate and don't want to make any changes until I understand a little more.
Did you ever find how to save your changes ??
Also I'm a little curious what the "hotel mode" is ????

P.S.
I actually received the sharp service manual for D5U series yesterday but it only covers the difference between D5U Vs D7U. "For all other information refer to D7U manual".... Boy that ticked me off !!!

Todd

bpmmmm,

Did you get your problem solved? I have the same problem. I can see the changes when I change the values and the values are saved between the sessions, but the display goes back to old (that is whatever it alway was).

I also have another question. In some menus, for example, HDMI menu, the first row is "HDMI ADJ", and next to it it says "ENTER". Have you tried that? I did, and it shows "////////" and then displays "ERROR" in red.

I will appreciate if anyone can help. todd95008, does your service manual say anything about this?

Thanks in advance. I am trying to find where I can buy the service manual for my 37D6U, but so far no luck.

The HDMI adj menu item (I think Sharp calls this HDTV so it's confusing) is for an auto adjust sequence for HDMI input with a specific test pattern being input on that connection. DO NOT select enter since it will fail the test if the incorrect test signal is being input (or no signal). The same is true for other input signals on RF & component inputs.

I think if you had the right test generator/signal, it will auto run the test and adjust the settings below that on that page of the service menu.

The service menu is very poorly documented in the manual and is very limited in the adjustment you can make.
What type of adjustment are you trying to do ??

Todd95008,

Thanks for the info. Extremely sorry for not responding! I was away for a while.

I am basically trying to get some colors that are easy on my eyes using AVIA disc running on my HTPC connected via HDMI. I don't have colorimeter yet, so right now I just want to get the colors to look okay to my eyes, no real grayscale adjustment. In HDMI, hue and color settings in user menu won't work, so I have to go to service menu. I am able to change settings etc., just not able to save them just like the original poster.

I just received the 37D6U service manual, and guess what? No service menu info! Luckily, I also got D4U manual which has some service menu info (although not exactly matching).

Looks like you have to unplug the cable after making changes in the service menu (as opposed to using remote or power button on TV) to force it into shutdown as per D4U service manual, but I haven't tried this yet. This may solve my problem.

Thanks again for the info. The service manuals that I found don't speak about this!

I have a smaller (32") Sharp Aquos set that I had ISF calibrated. The guy that did it was one of the best in the business and he said that the Aquos service menu is useless. Each parameter alters another and it's just one big mess.

I have confirmed this by speaking to 5 different ISF techs, who have all said that service menu calibration for the Aquos sets is impossible and a waste of time.

I still had my set calibrated through the user menu with the proper equipment by the ISF tech and I must say it looks fantastic. Not perfect, but 90 percent of the way there. Plus it was significantly cheaper.

Just thought I'd pass this along.

I could see how an ISF tech who's time is money is not willing to learn the peculiarities/features of the sharp service modes. It takes a great deal of time & experimentation to figure out the codes and yes the service manual is not that useful !!!

I have found that the user menu's are not very good for calibrating this set.
No greyscale cal and all the user settings for TV (userTV) are the same for different TV inputs (std analog cable, digital SD/HD and I-link inputs) are the two biggest problems.

kdragon, unplugging the power cord is the only way to save your settings !!!
This of course comes with a warning that if you accidentally changed a setting it will be saved when you unplug. Hue and color settings in the user menu should still be available for HDMI input (not DVI). I'm feeding a 720p signal via HDMI from panasonic sa97 and I still have these controls ???

Todd

I looked up the manual for another member (he had a LC-26D7U) and I found (page 46 of the manual) that you have to set the "Black" control to "ON". If you don't, you will not be able to set the gray scale correctly. I have seen no mention of this in any of the previous posts. It appears that the default for this control is "OFF".

Is it possible that no one has recognized this? Since I do not have an Aquos display, I'm just guessing that this might be related to this problem. The manual is a little confusing without the display to play with.

Greetings

While a pain, I have found that the sets can be calibrated okay. Just don't trust any readings while in the service menu. As well the better the input signal, the more the set allows you to tweak. A composite video signal cannot be tweaked very well at all. Lack of controls ... for instance.

Thanks. Yes, I did try it and it works. I have DVI output of HTPC connected to HDMI input via DVI->HDMI cable. I will double check if color-hue are available (last time I checked, there was no visible variation, but that may be because of limited range in which it changes). In any case, I have now decent colors setup with service menu adjustments for HDMI. Only can't figure out how to correct what I see through green filter (looks like green is bleeding into blue primary -- or vice versa. Quite strange) with DVE's color pattern (forgot the name).

Four more inputs to go!

I also found that the best (and only feasible) way to make changes in the service menu is by entering the detailed (64 page) service menu by pressing "Display" button while in Service Menu. If I make adjustments from the main service menu, all the adjustments that are made would be way off, that is, cannot trust what you see on screen; it appears the main service menu has some alpha-blending going on. I discovered this by a lot of trial and error.

Once you press "Display" a detailed menu appears which allows you to change all the settings, only difference being there are 64 pages to go through. I just had to find everything with "_HDMI" in it! Got good results for the naked eyes. :)

Glad to see that this works and you found hidden expanded service mode pages.
My D5U series has 159 pages !!!
I don't know why the manual does not refer to this ?
I just happened to find this by accident last week.
This let me changed some color & tint offsets that were way off for TV settings (analog Vs DTV).

If you don't mind could you record and post your Gamma settings ??
They are located in the expanded settings (not sure what page out of your 64 ?) and are labeled something like M_GAMMA level 1 thru level 6 for each of the 3 colors.
I have been trying to get the gamma curve right on my set since I changed the white balance setting (per service manual procedure) but think this screwed up the gamma curve so any settings you have form your set will be a big help.

Thanks
Todd

Can anyone PM me the procedure for accessing the service menu on the Sharp Aquos LC-32D5U. Not even the service technician that Sharp sent out could figure it out (how sad). You can PM me if this type of thing is not allowed on the public forums...

Thanks in advance...

Hello all. This is my first post here :)

I have just bought a 37D90U a few weeks back. Last night, I've started doing the basic calibrations using the DVE disc, and was able to get the test pattern to look decent through both blue and red filters. However, image thru the green filter is off and cannot be adjusted using the color or tint setting.

Can anyone tell me where I should be looking in the service menu (or better yet, a manual on the service menu that may point me to the right direction) to adjust the settings?

Thanks a lot!! :)

does anybody know how to access the service menu on the d40u series or the d62u series, i have both and need to make a few changes

If anyone has any hints as to what the various settings do, I would be very interested if you could post them here. I hope to calibrate mine, but am hesitant to change settings without knowing what they do.

The "Hotel Mode" is just a setting for hotels/pubs.

It allows them to turn the side buttons off so that people can't change it with out the remote.

Their for the person behind the bar is able to change it with out customers changing it manually.

If you would like more detials regarding this PM me.

Thanks
