I have been on here bitching for weeks now. So here is finally the best I could do to share this with you all. I have no means to screen capture other than my camera. i realize this throws in more variables, but I picked images that were the most revealing of what I have been going on and on about with my 52FA97. Read my other posts. There is a problem with his set. It is not normal for all faces to only show up as yellow or mgenta blobs. The yellow-green around "thin" skin areas and highlights really drives me nuts. Hope I can do this right.

Okay, here is the same shot, one with warm color setting, other with cool. It is almost more noticeable in cool as the yellow/green is more contrasting. Again notice how it is on his cheek, forehead, nose and by eyes. Yes I know this is an outdoor scene (sd by the way) but this pops up every where. In fact he is standing in shade.http://www.photofreeway.com/data//1158/medium/blackwarm.jpg

This one of Tom Cruise face shows it great. Again, yes I know it was a warm shot outside. But the yellow blotches and magents are all that ever shows up. Those yellow "blobs" are not normal. I have viewed exact same source on another set and it is not like this.

It could be the " I just threw an INT to lose the game" face. But does it have to have the yellow-green blob?

Almost done here. More of the red-magenta-yellow blobbed skin.

Second one. Notice there is absolutely no detail where the yellow blos are at. This is the episode of OCC I saw side by side with a G series where it was obvious this sets problems.

Often I find these kind of complaints picky, but I have to agree this is bad if you can't get rid of it with the user menu. I wonder if any of our professional calibration experts here can comment on whether that might fix it.

Like you say, my G-series has none of those problems.

I am glad someone else can see it. The only adjustments that I can see in the service menu are RGB gains only. All else is binary type stuff that I have no iddea. This by the way is with the yellow and green lowered quite a bit from what they started. Like I mentioned the in store display one has the same issue now that I see it.

Are you in Theater Mode, Standard, Vivid, or Game. I'm guessing that this occurs in all of them, but it may be lesser in one than the other.

Could you post your settings, and possibly your RGB values from your service menu?

I have a very slight issue with this on my set, but it isn't nearly as bad.

...The only adjustments that I can see in the service menu are RGB gains only. All else is binary type stuff that I have no iddea.

Just to be sure, are you in the service menu or the user menu? The difference is that you have to have special training and equipment for the service menu, whereas the user menu is easy to use. Have you compared your USER menu settings with ones posted on the various F-series threads? Most D-ILA owners, myself included, have found that we can get a really good picture just tinkering with the user menu.

User menu I thought was just the standar Pic, Bright, color, tint correct? Service is what you get into by going to sleep timer and pressing 2 buttons (cant recall right now) correct? I am not at home to check but off the top of my head in Theater mode (DVD and HD) I have color about -7 brightness also -7 or 8. Tint at Zero or -1. And picture (whites) at -23 WITH smart picture on! If SP is off I HAVE to have it at -28-30!
In what I am calling service menu I took all 3 values down a bit leaving red slightly higher as one has to be above 125. Other than that there is nothing that I can safely adjust.

The menus seem pretty bare.

Standard menu has Tint, Color, Picture, and Brightness. It also has the Smart Picture, Dynamic Gamma, and some other little stuff like that. Unfortunately, this set lacks the dynamic iris, which is the main cause of problems (I think).

I'm not an expert on this (I may be totally wrong), but I think higher numbers of red and green in the service menu would introduce red and yellow tones to skin. Red and Green make yellow. Have you tried calibrating the colors of the set using a calibration dvd?

Before taking this any further, I think it is important to read up on the user menu on various threads and in your manual. I strongly recommend not fiddling with the service menu further. One of the calibration disks would be a good investment. It took me a couple of months to get my TV where I liked it. For the first few hundred hours the bulb is still breaking in, so that alone changes things.

This is from the user's manual


TINT
Tint allows you to adjust the levels of red and green in your TV picture.
COLOR
The color function lets you make all the colors in the TV picture appear either more vivid or
subtle.
PICTURE
Picture allows you to adjust the levels of black and white on the TV screen, giving you a darker
or brighter picture overall.
BRIGHT
You can adjust the overall brightness of the TV picture with the Bright control.
DETAIL
The Detail feature adjusts the level of fine detail displayed in the picture.

I apprciate the help but I am aware of what colors affect each other, as I used to be a color corrector for digital photo labs. All based off of the CMYK on calibrated monitors. So I have a pretty good eye for colors. I have done my homework on both the user menus as well as the service menu. I also have the service manual. I am telling you there is something wrong with this set. Iris may be a part of it I agree.

Looks like Plasma clay face images !!

I don't have this set, but I do have a bulb RPTV (DLP) and it is sharp as a razor with detail to drool over.

I'd be looking into getting your set looked at ASAP !!

Mickey I am pretty sure I am just going to throw in the towell tonight and either go with the G series (a "step down" to 720p) or perhaps the 56N if they had one open box (wifey price restrains) or maybe even the freaking Sony 3LCD E series 46 or 50 which is what I started with over a month ago. I just know I will be disapointed in the blacks of the Sony. But we shall see.

By the way my set looks pretty awesome with inatimate objects and lizards as well. it is skin tones that goes crazy with the yellow-green blotches. Got any shots of faces in HD or SD?

gb33, I have the same problem with my 52G787. Slight yellowish green cast in the shadows and thin skin tones (ie. 5 o'clock shadows on men), red yellow blotches in faces ect. Only owned the tv for a couple of weeks and still trying to tweak it. Used AVIA to try to calibrate it as a starting point then adjusting from there by eye. (I know color too after being in the printing industry for 20 years. CMYK, RGB color space ect.) That did seem to help a little but it is still there. Some program material it is more noticeable than others. Some OTA HD programs look fantastic some don't. I know that directors use certain lighting to create a mood but I see it more that I feel I should. Have not got into the service menu yet as I do not have a service manual. Have any service menu adjustments that you have made helped? Just wanted to let you know that the G series has the same problem, at least mine does. Are we being too critical? My wife did not notice until I pointed it out to her.

I ordered the52FA97 but read this thread and cancelled the order. Did i jump the gun or should i reorder it?

I notice some of these but only on certain channels. Good HD and SD (for example, Discovery HD, HDNet) never has it. As far as I'm concerned it's simply a broadcasting issue. And I agree with your wife, none of this is at all serious unless you focus on it. I find if I just relax and enjoy the show it's never a problem, regardless of the channel.

As for tweaking, the bulb breaks in for the first few hundred hours and changes temperature, so you won't get a stable adjustment for the first while.

This sure looks to me like the blue channel is clipping (i.e., the blue signal level is too high for one of the signal processing chips is reach is maximum output value before the needed maximum blue level within the video image is reached). This may only be a calibration issue, but it could also result from a circuit failure. You can try lowering the overall image contrast, but if the blue clipping is occuring earlier in the signal processing chain this won't help. If you can access the RGB gain controls I would lower the blue gain first, causing the image to appear yellow, then lower the red and green gains to restore the correct color balance. I have also had a case where a chip failed (on a different brand of HDTV) and resulted a 'stuck bit' in the blue processing causing only certain specific signal levels to result in the displayed blue level to be way off.

GB33, did you end up getting a different set?

I'll take some pictures of my set tonight.

It looks just like my 61fn97 when I first got it looking on crappy SD channels, I have to go into the service menu and take the green gun all the way down to 100, you said you took all guns down, if you took all guns down at the same value then that do nothing, if you don't want to get somebody out and calibrate it for you, you will need atleast a color bars and grayscale to adjust it, and who said that you have to keep them above 125?

By the way my set looks pretty awesome with inatimate objects and lizards as well. it is skin tones that goes crazy with the yellow-green blotches. Got any shots of faces in HD or SD?

These are not stills, they were captured from motion, I just used a very high shutter speed with no flash on my Digital SLR. But I assure you my fleshtones are very awsome as well. I will try and get some pics for you .. maybe this evening.

Actually, here is an older shot ... but once again ... the blue hue on the top was due to my camera being to low on the tipod ... I will still try to get a few new shots of flesh tones for you..

http://img186.imageshack.us/img186/7329/samsunghls6767013uy0.jpg

As I said, not the best shot (actually crappy) ... I will get a better one for you. I know especially on "HDNet" the flesh tone and detail is AMAZING !! No crush of color and no BLOBS at all. I am not a fan of jaundiced looking people ... :D



Cheers

I am a man of my word ... here are some nice skin tone shots. Straight from my Sammy DLP to my Digital SLR ...

WOW! That is beautiful. I really wish I could watch a DLP. That looks fantastic. Great skintones & detail.
