THE SONY SERVICE CODES - Articles, Comments, Discoveries - Page 91

The signal is processed differently for the two scan rates. It is not unusual to have differences. Calibrate for each rate.

Thank goodness for AVS Forum. I have a 32" Sony KV-32HV600. It gave a beautiful picture. It even made VHS beautiful. It had some slight geometry issues. I decided to start from scratch so being a dummy, I hit that horribly magical 7, 9 combo that resets the service menu values. BIG MISTAKE! For the past week, I have been trying to get back to where I was.

I downloaded the service manual for my TV. One thing I noticed was that the resetted value in the TV and the initial values listed in the service manual differs. Anyhow, I have several problems that I need help with.

1. The resetted TV had too reddish a picture so I reduced RDRV and RCUT value. Now I have a greenish cast to the picture. The grey is greenish grey. Should I increase the RDRV and RCUT values?

2. The 1080i picture is not displaying correctly. When I input 1080i (either through both DVI and component), I only get partial picture. It looks like I only get upper left quarter of 1080i picture. Best I can put it is that the TV shows 480i portion of 1080i.

3. The focus is off. When I run Avia, instead of one line, I get one line "ringed" by a red line. This is worse in the corners. Maybe the convergence is off?

I appreciate any help you guys can offer. Thanks.

But what service menu items in particular should I be looking at? Gamma settings seem to be the most obvious if your looking at fixing black crush, but the gamma settings are both the same in 480p and HD...

I do not recall if that set has the ability to differentially adjust gray scale by scan rate. AS for the other problems, start with the initial settings in the manual. Be sure to check the option codes for your model. When you reset the EEPROM, it may go to a generic setting for a series of sets and not your model. I do not know specifially what data they have the system default to, but it is often different than the values in the manual. Keep in mind that the values listed as initial in the manual are generic and your set will require calibration beyond that even when it was new. Now that it has aged, the difference between the values listed in the manual and calibrated values will be even more disparate.

I just got a 34XS955 and there is a slight problem, the black level has a blue tint to it. i have tried changing 2170P-1 [7-13] with no real success, i use to have a 34HS420 with perfect blacks.. everything about my 955 is perfect imo except this blue tint.

anyone care to enlighten me on what i need to change? much appreciated.

Rylex,
As I recall, there are two settings for each color in service mode, a drive and a cut. Drive adjusts highlights, cut the shadows. Look at your settings and see if blue cut is set differently from red and green. Mine ended up almost the same for all three in an XBR 970.

fbov,
i have changed those but it seems to unaffect the blue tint in the blacks.

these are my settings. i have tried default with them all and even messed around with them, nothing seems to help, im thinking this tv was abused? left on vivid the whole time? its still under 3y warrenty from costco from the seller i bought it from. is there any other inputs i should be looking at? thanks.

I'm new to this forum, but I believe this is a good place for this question.

I just bought a used kd-34xs955n specifically for gaming on my xbox 360 because I am not happy with input lag and response times on LCD and plasma HDTVs.

I fiddled with the normal menus to get colors and picture acceptable. But I believe I am experiencing some mild overscan problems. When I play Halo 3 I notice that I should see slightly more around the edges of the screen. I still see all of my HUD and important info, so I cannot warrant paying someone to fix this, but I am a bit of perfectionist and it just irritates me knowing I am not seeing everything.

Also, on a much less important note, when I look at writing on the sides and corners of the screen, it seems slightly blurred (at least in comparison to writing in the center of the screen), and I think that there might be a bit of a curve to lines that should be straight. I am not sure if any of this is related to the overscan or not, but I just thought I would post it as well.

Anyway, I have searched the internet extensively and it seems like my only bets are either hiring someone to calibrate my TV, or using the service menus to try to solve the issue myself. Because it is only a minor issue, and I don't really need a whole calibration I decided to try to fix this myself with the service menus. I stumbled upon this forum, read many pages of info and downloaded the charts and things, but it is all extremely daunting because I have never even heard of a service menu until now.

So I guess what I am looking for is someone to help me with a detailed yet fairly easy to follow set of instructions for how to use the service menu on my TV to fix my overscan. As stated above I have a Sony KD-34XS955N.

Thank you in advance for your help!

Just as an alternative, here are my 34XBR960 values (parenthetical values are service manual defaults, if other than my values), significantly different from yours:

SBRT 0-63 28 (24)
RDRV 0-63 32
GDRV 0-63 27 (22)
BDRV 0-63 27 (20)
RCUT 0-63 32
GCUT 0-63 24 (16)
BCUT 0-63 31 (22)


Don't forget the other crucial color-related settings in 2170P-4. Here are my values (other users will differ, of course), which work to my liking with color temp = COOL and color axis = DEFAULT:

RYR 0-15 13 (8)
RYB 0-15 15 (9)
GYR 0-15 5 (9)
GYB 0-15 4 (6)


NOTE: these isolated but important service menu items are not all there is to the way color looks. There's also very important user menu settings (I have PRO, color = 31, hue = 0) as well as color temp and color axis. And of course, there's your own tastes.

Try starting from this post.

You will have to click on the proper secondary links to retrieve posts from the archives from (a) 2005-2006, and also (b) prior to 2005.

While the final numbers you end up with will clearly depend on the characteristics of your particular set, the general "recipe/approach" described in the above posts is still applicable.


NOTE: my geometry/overscan adjustments included tweaking MID3, as had been talked about a long time back in this thread. Since then there's been a "difference of opinion" on this subject, but I still stand by the way my 34XBR960 looks and it couldn't have been done without tuning MID3.

DSperber,
thanks for the reply, i messed around with all the settings you gave me, nothing changes it. im thinking its a defect or abuse issue.. here is a pic of what im talking about, black is not true black. my HS420 had PERFECT blacks, couldnt tell it was on when the screen was black. guess ill have to live with it. a lot better then blurry edges of my 420, and higher res.

Thank you DSperber. I will try following that link and see where I can get!

Thank you! That post had all the info I needed!

Well now that I have my overscan fixed, I feel slightly addicted to this tweaking in the service menus! So, I've noticed that it seems like writing in the center of my screen is slightly clearer then writing on the sides. Is there something in the service menu I can tweak to make the sides of the screen as focused as the center? I'm not really sure what to call this problem. It is a very minor issue, so it's not the end of the world if there isn't a fix.

Once again, I have a KD-34XS955N.

Thanks!

Hello all, It's been a while since I've been here.
I've been trying to get the output from my HTPC to my 34xs955 calibrated and have run into a problem.

I'm currently running my ATI HD3870 via DVI>HDMI to Input 7 (HDMI) of the set. Using Blu-ray discs from the LG combo drive through Powerdvd 7 Ultra my black levels seem completely crushed. A check of Dr. 1394's HD Test Patterns shows my black information stops before the last 15% of the scale (4 ramps and 2IRE bars missing). I should add that my HD-A! through the same input does the same thing now.

I can understand PC levels but it seems to be passing the white information fine. Made the mistake of referencing some old Word doc concerning settings for HDMI setting without writing my current settings down!

The menus I made changes in were: 3d-comb, 2103-1, 2170P-1 (except drive and cut settings), 2170P-2 and ENHA.

No matter what ammount of GAMMA or SBRT or UBOF I fiddle with I can't see any black info below a certain range. Is this a shortcomming of the 10-bit HDMI in thses sets or am I missing an important setting in the SM, Catalyst Control Panel or Powerdvd?

Very frustrated right now...

*UPDATE*

Appears that the HDMI input is the culprit. I ran the HD-A1 over component (Input 5) and no problems. Compared settings from Input 5 (3d-comb, 2103-1, 2170P-1 and 2170P-2) and they were nearly identical. Even attmpted to adjust the settings that didn't match, nothing made the black info reappear.

Anyone familliar with Avia, the HDMI input won't even show the moving black bars in the (Bars and Half-grey pattern)!

Is anyone aware of any HDMI specific settings that MIGHT need to be corrected? As it stands it looks like I'm down to 2 component inputs or the prospect of replacing the HDMI board.

Any suggestions for quality component switchers (on the cheap) so I can manage my 4 source devices?

On the HD-A1, make sure your "Enhanced Black Level" is set to "OFF" If you are still not seeing the black detail, increase "Brightness" to verify it is not in the signal. Some players/displays will not display the Below black bars from AVIA/DVE.

forgive me guys if this has been covered but i'm going batty. from what i gather reading over all of this info is that my problem can only be fixed by magnets. i'm setting up the geometry on my 34xs955 and i'm running into an issue. the horizontal lines on the right side of the screen are bowing up a bit...probably the last two inches or so. it kind of looks like this only with the upswing being a lot less severe:

is there a service menu fix for this or is it magnet time? oh, and a big thanks to all of your guys hard work....the amount of info in here is amazing.

Glen,

Thanks for the response!

Yes, I have all that "crap" turned off. I am aware (and o.k. with the fact) that the HD-A1 does not pass BTB via HDMI. The part that made me think it was the HDMI input was the fact that both my HTPC and the HD-A1 were showing the loss of black detail to the same degree.

Turning the "Brightness" up shows just how little of the black info is getting though. Huge swaths of the picture are just gone. I guesstimated from how many bars were missing in a 10 IRE pattern that the last 25%+ was missing.

Anyone know where a feller could purchase the board for this set? Part number?

Any chance you've been adjusting overscan?

Adjust it out and the edge of the picture is crap, and the only way to remove it is overscan. On mine, the edge of image looks like your diagram. It's part of the CRT world - that was the entire world until relatively recently you'll recall.

There are also a full range of geometry adjustments that may allow you to adjust it out. They'll also tell you what needs magnets. Look for the 955 service manual, not just service codes, on page 1's master list. Also look at focus and convergence, pages 10-15. Page 1 has specific links.

Have fun,
Frank

I need some serious help here

I have 30" Sony KV-30HS510 and i have it hooked up to my PS3 through HDMI/DVI at 1080i. I had been looking into service mode mods off and on over the years and only within the last 5 or so hours have I found enough information on the subject to actually get into the service mode.

The problem is this, after getting the overscan at 1080i exactly where I wanted it. I wrote it to memory and everything was perfect until I tried to use the "Copy" function explained at 4-1.18 in the "official help.pdf" found within the service mode help zip file.

After attempting to use the "copy" function (which in hindsight I must not have understood cause it certainly didn't do what I expected and right now I don't know what it does) my DVI connection froze for lack of better word at first I thought my ps3 had froze but nothing i did on its side changed the image I was seeing. I figured that I could reset the NVM data to fix it so i cleared mid and/or system NVM to see if that would fix any thing sadly it didn't. The service mode setting were a complete mess but using the service data pdfs I was able to fix the 1080i vertical and horrizontal settings but the HD connections on my TV don't do anything but display a random screen grab from channel 2(switching from an HD input to anoter input just refreshes the screen grab)

One thing that I did notice was right before the DVI died I saw something other than Service/Write/Read in the area where "SERVICE" normally is it was brief though I think it started with "IN" if I get the service mode to display that again and took note of it would that help you guys figure out what I did and how to fix it? Cause I need options when I go to sleep I'm going to unplug my tv and see if that clears up the issue with the HD input.


Note: While my PS3 is hooked up, on and in xmb or playing a video my TV in service mode says its getting a 1080i signal to bad my tv just wont display it.

*Also under every entry in the "ID" Data section is:

"M306V7MG-050FP
NVM: G"

Does that give anyone any ideas?

ok I know what preceeded the DVI going bust, it was my accidental clearing of mid nvm data(7-jump-enter) which causes "INIT-MID" to appear in place of SERVICE" for a moment now does anyone have any idea on how to repair/initialize the HD function of the TV. Other than that everything works fine.

I think i'm in trouble. I have a Sony KP-57WS520. I reset the service menu setting by accident and now my Flash Focus and Convergence will not work from the regular TV OSD.

Also now video 5 is HDMI, it used to be Video 7 like the back of the TV is labeled.


I need help badly please. Since I can't use convergence for some reason now, I can't fix my picture correctly

Well I got the HDMI & mostly everything else back to normal. I can't figure out how to get "Flash Focus" or convergence working again.. The screen blinks like it's trying to do something but nothing happens.

I see the Convergence overlay but not the crosses pattern at all, really odd. Flash focus just makes the screen blink and does nothing. HELP!

convergence and many of the OSD menu options are controllable in the ID string try messing around with ID7 in the service menu until you see convergence in the OSD


Now if someone could help me resynch hd on my KV30-HS510


Edit: Service Manual for KP57WS520 again I suggest skipping to the ID section and make sure you have the right settings

I can see Convergence and Flash Focus on the menu but why try to use them, they do nothing. No patterns.

Service Manual for KP57WS520 again I suggest skipping to the ID section and make sure you have the right settings

as for me I have found the service manual for my tv but I am confused as to how I should configure my mid 5 settings its just a table of numbers that don't seem to make munch sense

edit: I now understand how mid 5 configuration works. (Choose a pop setting # 0-56 than configure everything from 1-18 rinse and repeat)I would however love it if someone with experience in restoring a tv after nvm reset could tell me if proper configuration of the mid 5 will allow me to restore my tv's hd connections

Freaking awesome! I cannot begin to thank you enough for posting that link!

*bows*

Hey I hope it helps you out man. In order to find the service manual for my tv I had to register and subscribe to nodevice.com.


I have a month long subscription so if anyone has a user or service manual they need request it now and if the manual helps you out a small donation to my paypal won't hurt.

There are somethings I could use clarification on. In the various service menu guides terms like VDO, CV/YC come up what are they refering to exactly?

also what about Vcomp? I usually see it as a setting where FULL is also an option so I imagine Vcomp is for twinview, index, and freeze is that correct?
