Tweaking Tips For SONY Owners!!! - Page 3  

post #61 of 258
ok I dont know what I did, but I must of set something by mistake, but everytime I watch hd channels it is in full screen. Now i have the sony kv36hs420 which a 4:3 set so it is not suppose to be fullscreen and plus they look stretched out vertically and now i have screen set options in the normal menu none of which help. another problem is that my screen looks like it is being squeezed in the middle and is noticable when watching 4:3 programs on hd or dvd menus that are boxed .

Interesting, but I can't seem to get into the SM since the last time I was in. I pressed: display, 5, volume+, then power with the tv off and just turns the tv on and won't open the menu.

Press volume up once, and keep trying you should be able to get in.

Your set must be on before you sequence through the keys. With your TV on...... press power(off), display, 5, vol+ and power(on) all in quick succession.

Finally got it. Thanks

Make sure you have TV selected on your remote. It is quite easy to
have inadvertently chosen sat/cable. Press the TV function key again, you should get your menu button back. Again, the TV should be on when you sequence through the keys and you must press them firmly but in quick order with almost no pause.

You guys have any other tips i could use?

Any tweaks that helped improve picture quality?

You bet! I have found that repeating this phrase whilst tweaking improves my image!

teckademic: Last week, after leaving the service menu, the HD channels looked stretched for me as well. I changed the ASPT service menu option from 0 to 1 or 1 to 0. This gets switched up randomly sometimes when I go into the service menu for some reason. I am not sure if it is ASPT or something simular because I dont have my set where I am to check it. Give this a shot because I think I know what you were describing.

I am not sure this applies to your problem but make certain that the picture size and the picture format settings are correct via your cable box remote and that the cable box service menu which you can access is set up for your TV and its display resolutions. Trust me this is not always set up properly by the CABLEGUY.
post #74 of 258
First off, I want to say this is an awesome thread. I've been spending the past week making all of these tweaks recommended here and my PQ is 10x better now. So thanks all for that.

I'm posting b/c I am watching SD right now and there are vertical bars about 2-3 inches thick, running from top to bottom of my screen (not really sure if this is true on DVDs also).

Only seems to appear during brighter scenes. I could have swore I have seen posts regarding this, but I can't come across any right now, so I thought I would post and see what people thought.

I have a Sony 34" Widescreen Wega KV-34HS510. I have never noticed these before. I have the screen paused with my tivo with the bars noticeable and tried to go through the changes I have made in the service menu and nothing seems to change them.

Anybody know what my problem might be?????????

I do not think it has anything to do with the cable box or anything other than the tv because it never used to do that till I went into the service menu. What settings adjust focus?
post #76 of 258
Initially you could unplug your TV for a few minutes and then reconnect it and see if this has any effect. If not, hopefully you copied all of your initial before and after settings. You could return them to their default values. That should restore your set to its original state.

While in the service menu press [8] and then [Enter] on the remote.
post #78 of 258
doing that only resets all settings but the service menu and i did save all settings, but i must have changed one unintentionally which is why I ask if anyone would know.
post #79 of 258
Per my post on page 1 of this thread. I've finally got DVE and am watching and learning it start to finish (not completed yet). I've read this thread over and over and then a few more times.

One question before I dive into SM. Do the changes appear as you make them or do you have to power off/on for them to take effect?

Please indulge this SM newbie.
post #80 of 258
I usually lurk over at the CRT projector fora, but since picking up a KV27FS120, I'm looking to work on the picture. A lot of the things I work on with my projector translate here rather nicely; except convergence. :( I found a webpage that lists the SM items and gives a brief discription, including the convergence options. However, they include a footnote that the convergence options are disabled on 27" and smaller sets.

Can people here confirm that I'm doomed to corners being slightly out of convergence for the rest of the TV's life? Any hope at all? Is there a super-secret convergence menu I can jump into?

Side note, I noticed several menu items prefixed with PIP and they included video setup items... does this mean that this set, which does not advertise PiP ability, may actually have PiP in there, just waiting to be turned on? The included remote (RM-Y168) doesn't have PiP keys, so testing for this may be futile.

Thanks in advance. :D

ceeller, the only you will be able to fix the convergence errors is to have a tech come out to your home to make the adjustments inside the TV. My Sony 30HS420 has convergence errors in the corners and am thinking of having tech come out to make it look better. The D-CONV (convergence) settings in the service menu are disabled on the cheaper Sony TVs for some reason.

Changes appear as you make them, but to make them stick you need to press the [MUTE] button and then [ENTER] on the remote. After you're done saving your new settings you need to power off and then back on to get out of the SM.

Dark, do you know if the convergence controls are the classic bank of adjustment knobs? If converging a tube TV is no harder than a CRT projector, then I'll take a stab at myself. :)

thanks.

I have been trying to understand how the MIDE value affects picture detail, absent a definitive document from Sony. Word is, the official service manual doesn’t go into as much detail as I want. (Am I wrong, anyone?) So it’s like a game: try a bunch of stuff, and try to divine the rules. Surely, among a group of wireheads and obsessive-compulsive types (maybe Myst devotees) on this fine forum, we can move ahead in characterizing these codes and keep adding to the code chart that is widely circulating (Excel spreadsheet).

I am willing to bet that the acronym stands for Matrix - Image Detail Enhancement. I am experimenting with my own newly-purchased 36XS955 set. (Yes, I am very, very pleased!)

What seems certain is that changes on-screen are not monotonic with changes in MIDE, i.e. things do not steadily change in one direction as MIDE is altered from 0 thru 63. It seems all anyone can do is note the picture characteristics that correspond with specific MIDE values, and make detaled notes. Maybe there is a pattern, but I haven’t found much yet in that area. But here is a first try:

(1) As you go from 0 to 63, both vertical and horizontal detail enhancement is increased or decreased, but not necessarily both together. If you pay attention to vertical fine lines (horiz detail) and alter MIDE, enhancement reached various peaks and minimums as you advance MIDE. The same is true of horizontal fine lines (vert detail), but the peaks and minimums are generally at differet values. I.e. some settings keep vertical enhancement at zero and set various amounts of horizontal detail.

Vertical detail enhancement is obnoxious to me, always appearing coarse and false. It appears that some values of MIDE that keep vert enhancement at zero are 0, 8, 12 20, 24, 28, 36, (etc).

(2) Horizontal detail varies without a pattern I can see yet. 0 seems neutral, 1 mushy (a detail decrease?), then all others vary from neutral (0), to moderate (5), slight (8), extreme, (18,19), etc. in numerous combinations.

(3) Being conservative, then, settings of MIDE = 0 or 8 seem to minimize enhancements. I am trying to optimize high-qualiy broadcast television, and so “balancing†horizontal and vertical detail is a reasonable goal with the best sources. For me, this is MIDE = 8. More horiz detail enhancement also exaggerates noise in the picture and has a downside.

If MIDE truly is a matrix of, say 8 X 8 independent parameters, then I wonder why it doesn’t show a pattern. If, for example, vertical and horizontal enhancement had 8 levels each, and this was an 8 X 8 matrix of those values, then it would seem reasonable to make the MIDE numbers correspond to cells in the matrix, numbered across, then down, or the reverse.

But perhaps there are more than two (H and V) parameters. We’re talking digital image manipulation, here, and if there is a complex polynomial defining detail enhancement, then some of the matrix’s values could be higher or lower-order coefficients. For example, some settings may appear to be identical with even the best broadcast TV, but one would see the effects on a fine HDTV signal or on DVD. (The *dimension* of the enhancement for those settings is much smaller and does nothing for the coarser SDTV signals.)

Fortunately these settings are complete independent for the various picture modes, inputs, and video modes. So one can optimize for SDTV and leave HD ot DVD material for another day and more fiddling.

I hope I am not being too anal for anyone here, but I really would like to dig a little deeper into how these parameters affect video display on these marvelous XS-series (and other related) sets. I have an engineering background, and I hope to bring some clarity (as opposed to simplicity) to the discussion. I’ll continue to post proposed revelations and discoveries, and I hope that others might do the same. I have gotten a *lot* from what I have read here so far, and I want to contribute, too. I’ll post questions in separate messages.

Should we start another thread with the focus of *just* Sony service-code discussions?
post #85 of 258
In Sony service mode, everything seems fairly obvious -- except the WSL readout. It usually flickers between 0 and 1, but I have seen it up in the mid-200s when I was changing values for a DVD input on S-video.

Does anyone know what this means?

I've read somewhere that they have to use magnets and/or make adjustments to the deflection yoke. I've also read about resetting the TV software to correct it but I'm not too sure about that. It's probably best to let a certified tech fix it.

Ohh, playing with the yoke magnets is NOT fun. In that case, we'll see about either living with it or finding a tech. I still have to crack it open as the onboard speakers are not putting out any sound. I'll take a peek at how the convergence may be handled, just for fun.

.... (edit) ....

Though, now that I think about it; the yoke magnet assemblies are usually used to correct point astigmatism, not convergence. If there is convergence control in there (has to be), it'll probably not be connected to the yoke assembly at all. Hmmm, more to ponder.

Thanks,
Chris

Ken, I'm also stumped on the MIDE parameters. I have found with MIDE = 8, 480p, all other edge enhancements off, the value of 8 reduces "ringing". With AVIA, and looking at the sharpness pattern, the letters "SHARPNESS" are very distinct with no ringing at all, increasing to 13 or 17 etc, you can definitely see some enhancement going on.
There's a guy over at the SPOT that seems to be up on his MIDE tables, I'll contact him and post back his suggestions.

From loadams:
> increasing to 13 or 17 etc, you can definitely see some enhancement going on.

Yep, peaking in both vertical and horizontal directions at 18-19. Then, when you go to 20, everything is conservative again, with little enhancement, and I am wondering what, for example, differentiates 8 and 20.

> There's a guy over at the SPOT that seems to be up on his MIDE tables, I'll contact him and post back his suggestions.

Wonderful idea! (What's SPOT?) And maybe he can shed some light on this:

The, um, *interesting* SYSM sharpness parameter (OFF = 3) is the only sharpness effect that seems to map to the Sharpness slider in the user menu. Setting SYSM to 3 removes several idiosyncracies from fine detail, notable the "double image" effect mentioned by others when SYSM = 1 or 2 and the Sharpness slider is set to minimum. But now one doesn't have a way to spiff-up the detail in, say, crappy broadcast video, except to program one of the picture modes just for that purpose. I wonder if the Sharpness slider can be mapped to any other detail-enhancement parameters.

I have an older 36XBR400 service manual as well the newer 34XBR910 manual. Interestingly the older manual contains more Control Register function/link information for each of the Register Names. SYSM is described as SYSTEM: Signal Bandwidth Setting and MIDE is described as MID enhancement setting.
