THE SONY SERVICE CODES - Articles, Comments, Discoveries - Page 21

Hey guys,

What other things besides SBRT and YOF can i use to tweak black levels?

BTW -- WHAT IS YOF ANYWAY? It was originally at 12 and I turned it up all the way to 15, which seems to lighten up shadows (which is what Im trying to do).

I tried raising RCUT, BCUT & GCUT to no avail. Didnt seem to make much a difference.

What else can I try to crush the black crush?

I had a similar experience with my 34XBR910. I called sony Service and arranged for a sony authorized service tech to come. The solution was to replace the memory stick module board. Has worked fine since.

what about GAMMA correction?
talks about it on page 1.

mr2828 / jjmilo,

Thanks for the information. Although it sounds like the memory stick and user settings loss are not related, the memory stick function is needed to fix the user setting problem. As my 2 year warranty expires in the next 2 weeks I guess I should forget covering and ignoring the memory stick light and call for a warranty service visit.

Any other experiences would still be appreciated.

Regards, Rick

You factory settings worked great! Thanks!!! \\
I have the service manual and the settings in there are umm how should I say..."not right" LOL

Anyone else use the service menu to calibrate their KV30HS420?

I've resolved to calibrate my system using it, but I was hoping to get in touch with someone that's been through it before.

If you like, you can send me a PM and we can discuss it. I'm trying to wrap my head around all these different service codes. Not very easy.

I have a problem with my KD34XBR960. There seems to be a bluish/purplish color in the bottom left corner that bleeds into the rest of the image. I was told that this could be caused by electrical interference, so I moved everything electrical away from the TV and unplugged it for about 4 hours. Didn't help any. So then I hear two other things i've yet to check out: one person who had this exact problem with this exact model said they got a Sony rep to look at it, and he needed to adjust something with the calibration. Another person suggested messing with some kind of option that deals with how the earth's magnetic field can affect the TV, but I found no such option.

Basically what i'm getting at, is is there any option in the service menu that could help a problem like this? I'm very new to this kind of thing, and would rather not just go in and start messing with stuff. My last resort will have to be shelling out money to have someone come out and fix it, but i'd rather avoid that.

I have use the SM to make some adjustments to my 34HS420. And access to the SM is required to perform some of the trickier elements of calibration (e.g. overscan, sharpness, etc).

My efforts have been those of a newbie following the directions of others. Go ahead and PM me and I can at least point you to some helpful posts.

I had some success recently fixing some color purity blotches on my 960 using the LANDING settings in service mode.

i just noticed that the edges on my 30HS420 are slightly blurry(not as focused as the center). has anyone tried the focus codes?

I actually just did a calibration of my 30HS420 last night. I went a slew of codes, although not even close to as many as KenTech.

I basically went through and fiddled with: HPOS,HSIZ,VPOS,and VSIZ for size and position. GYR, GYB, RYR and RYB for color, UBOF and SBRT for black levels, and QPAM thru QPDP, DF, and DQP for focus and clarity.

I would've done more with color, but KenTech's post outlines using clouds as a white reference. I was calibrating at night, and I wanted a more reliable method. So I used DVE with the filters, and the color codes mentioned above. I have actually gotten VERY good color results now.

The focus codes also did a wonderful job on my picture especially with SMTPE 133 res. pattern.

I was watching some HD and SD content yesterday, and I am very pleased with the results. My only gripe is that the whites seem too white and the blacks seem too black. So I'll continue to do a little more adjusting, but Brightness and Picture in the Video Options should suit me just fine.

If you'd like to know the group codes for the items mentioned above, feel free to PM me. Anything I know, I learned from Justc, Crockhunter, and KenTech of course.

Do you know the code for this setting? I can't find anything like it.

This is very good news. Congratulations are in order.

I also have times when whites are a bit too white - like when watching football in bright sunlight, the players white pants or jerseys can seem very "overexposed."

Isn't it wild how much better your PQ can be with relatively few adjustments?

LAND 0 through 9

on my 960. If you don't have a 960, you may not have these?

You are a little angel, you know that? Haha.

I thought I was gonna have to spend several hundred dollars getting this fixed, but that did it. Had to change one of the settings (think it was 7) from 0 to 1.

I've searched the thread and found a number of you that have adjusted for overscan, but not a lot of details on the specifics. Can someone do a quick walkthrough of a "surgical strike" of getting in, reducing overscan (on HDMI input), and getting out? I've got a 34HS420.

Thanks.

You need to be able to put up a test pattern to correct for overscan. That can be difficult to do directly on your HDMI input unless you have an upconverting dvd player connected there. Most of us use either the Avia or DVE calibration discs since they include all the test patterns you need. The only other way to do this on the HDMI input is to somehow get a test pattern broadcast to you - with Comcast Digital Cable, INHD broadcasts test patterns every Saturday morning at 4am EST. And they do put up such a pattern.

Once you have a test pattern you can use VPOS & VSIZ (in the Service Menu) to adjust for overscan vertically and HPOS & HSIZ for the horizontal.

This is meant to be humorous, right? I'm not trying to be facetious, but this subject has honestly been discussed in great detail in several threads... especially in a number of recent threads posted by new XBOX owners seeking to tweak their Sony sets (e.g. XBR960) to eliminate overscan.

Assuming you're into the service menu (and are familiar with how it is entered, used, saved, and exited), the primary recipe approach is fundamentally twofold: (1) use the VPOS and VSIZ items in the 2170D-1 group, and the HPOS and HSIZ items in the 2170D-2 service menu group, to adjust the "background raster" (aka "canvas") in both horizontal and vertical directions. Then (2) in the MID3 group you use 0 (VDHP horizontal position), 1 (VDHS horizontal size), 2 (VDVE vertical position) and 3 (VDVS vertical size) to manipulate the 1080i/720p "image" on top of the "background" (i.e. within the "background raster").

2170D-1 and 2170D-2 are used to adjust the "canvas" to reach to the physical edges of the screen, so that the image then placed on top of it can utilize all available screen real estate. MID3 is used for the 1080i and 720p image size and placement adjustments, within the background raster area set by 2170D-1 and 2170D-2. You position and size the image over the background so that it is fully visible and reaches to the extreme edges of the background for 0% overscan. Then you enlarge it just a bit more in all four directions (using the test pattern on your screen as the guide) to "crop" out the video noise which you may see at 0% overscan, losing perhaps 1-2% of the image in this final "overscan" adjustment.

As you get into each part of the adjustments, clicking up or down one unit at a time so that you see the precise results of your tweak, you focus on getting the extreme outer edge of the test pattern rectangle visible on your screen. When you're done (at 0% overscan), the complete rectangle should be totally visible on all four sides. No wasted screen, and nothing eliminated (at 0% overscan).

There is an assumption that you have a proper 16:9 test pattern on your screen, the best of which can be found attached to this post which if you can connect your PC to your HDTV is ideal. If you have a video card like ATI Radeon 9800 Pro, it has a second DVI head and you can connect it to your Sony with a DVI-to-HDMI cable setup. Or, you can get the ATI DVI-to-component adapter and connect the second head to your Sony with component video cables.

Otherwise, you can use Avia or DVE DVD's to display geometry and overscan test patterns, though at 480p. Using DVE, you can go to Title 12 (Display Setup Patterns) and then Chapter 17 (1:33 overscan pattern), with the latter "spread" to 16:9 by the MODE button on your remote.

"Blow-by-blow" as well as instructions for service menu entry, exit and use, can be found in this post .

Hope this helps.

Perfect, thanks.

Hello everyone well first off before I ask any questions I would like to thank everyone who posts here for the wonderful information that I've gotten from this thread and board so far, its really made me happy with my purchase of my kv30hs420. Now for my question, when I watch dvd's and other things like games words sometimes appear to be blurred to the right. For instance when watching pulp fiction the orange lettering in the opening credits seems to blur to the right almost to the end of the screen, now it's a very light blur but its there and I was wondering if anyone had any idea at all about what exactly I would have to do to fix it or at least what could be causing it. Thank everyone again in advance for the help

Use the function "Search this Thread" and search for "focus".

I find this to be "normal" for an interlaced signal. Try setting the set to progressive (480p) and see what happens to the text. I realize 480p may not be optimal for viewing, but it can cut down on the "blur."

Happy Holiday.

I have a few questions about my XBR960.
Any one have any idea why the CCD menu does not show up in my service menu?
Any idea why items 7 through 12 in 2170P-4 are listen on the Service manual but do not show
up on the TV service menu?

When adjusting the zoom, wide zoom, etc, does one bring that up on the screen, adjust, and then write?....will that affect the normal view?

Any suggestion as to what I could do to input a pattern to the Cable input?

FYI. I am using ATI 9600 all in wonder. I bought a VGA to YPbPr adapter. Using the software and dip switches, my TV tells me it can get a 720p signal.

Thanks...

The Sony Service Manuals are not easy to understand, and they are not always correct. The two examples that you mention are the best known. But there are also menues in the TV that is not in the Service Manual, ex the QM menu. I have two versions of the 34XBR960 service manuals and they are different in several areas.

Correct, it will not effect the normal view if the service menu has a specific entry for the particular zoom. If there are no specific entry in the service manual for the zoom or for the input, the change might be global, so you always have to check the service manual.

Hi There!
A help on a description of service codes in a Sony KV-J29MF8 Chassis SCCK57Q-A is well come
Many thanks to all of you.
Baule

Ok..Thanks.

Does anyone else beside me, have a time of it trying to make the geometry perfect?
I have the overscan just right, and the pic is all centered.
The edges are clean, etc.
The real concern is when I watch a broadcast, if the camera pans quick, I can see the distortion.
Any easy fix, or is this all by eye with a cross hatch pattern?

I am really in need for some help. After reading ken's guides and other overscan guides i have read on here, i have completely screwed up my tv even though i "thought" i had it. The only excel sheets i can find are for an xbr and a 30hs420 in which things are not getting better. Can anyone find or post an excel sheet for the kv-34hs420. please...

The absolute first post in this forum contains the original sony service manual grid for your TV. You cannot expect a perfect result just by putting in the numbers from the grid, and you cannot expect the different excel spredsheets out there to give you a better result. All tube TV's are "temperamental", and if you want to fiddle, you better be careful.

I suggest you write about what you did, which menues you changed and what went wrong.
