THE SONY SERVICE CODES - Articles, Comments, Discoveries - Page 99

I can't speak with authority on this, since I've never owned an SD Sony tube (only HD). But 480p would require a higher scanrate than 480i (31.5 kHz versus 15.75 kHz). So it seems unlikely to me that you'd be able to convert a 480i tube to 480p by simply throwing some switch in the SM. 480p also requires add'l processing to de-interlace the image.

I do not recommend using 480p on the Sony HD tubes btw. IMO, it's more fatiguing to the eyes than using 1080i, and the phosphor persistence is worse. (Note: both the Progressive and Cinemotion settings for 480i inputs will display as 480p on the HD tubes. So I recommend avoiding these as well, if you can.)

It looks like the 36FS10 also predates "V-compression", which was added to alot of SD TVs later on to improve the picture quality of 16:9 video content (e.g. widescreen anamorphic DVDs).

If you can get into the SM on the TV, you might be able to "convert" it to a 16:9 TV by squeezing the video image with the vertical sizing controls. Then you could change the setting on your DVD player to 16:9, and watch widescreen anamorphic DVDs at full 480i resolution.

I did this on one of my older (non-Sony) 480i tubes, and it worked quite well. Only problem is you have to go back into the SM and switch the vertical controls back whenever you want to watch a regular 4:3 source properly, which was a PITA.

i recently did a factory reset via the service menu on my bravia ex320 and now the rgb signal off my virgin box is really fuzzy especially on the blacks and greys like on the on demand menu can anyone help / have any idea what would cause this maybe i pressed something in service menu by accident??

Hey there, im in the same position, trying to adjust my 34HS420, any luck for u ?
would u be kind enough to send the right values on the service menu for me ?
my tv colors looks horrible after a friend of mine trying to tweak it , what a genius ah

You should never reset the SM on the Sony HD CRTs, under any circumstances.

Resetting the SM will not restore the TV to the original settings when you bought it. It will erase all data in the SM, including settings/tweaks made at the factory which are crucial to the TV's basic operation.

NEVER...

EVER...

EVER...

EVER... reset the SM.

If that's what you've done, then I think these your basic options:

a) Try to find a professional calibrator who knows his way around the Sony CRTs, and thinks he can fix it (which is becoming somewhat hard to find).

b) Take it to a Sony authorized repair shop, and hope they know what they're doin.

c) Contact Sony Parts, and ask if they still have a "900" (ie fee-based) nonauthorized technical support line where you can get some help. (Note: you may need a copy of the service manual for this as well.)

d) Order a service manual and try to fix it yourself (which may make matters even worse if you are not a very technical person, because there aren't really any detailed instructions included in the service manuals).

e) Try to find someone else with the same model, who's written all their original settings down (like you should have done in the first place), and has the time to help you figure it all out.

f) Accept that you made an unfortunate mistake and look for another similar TV on Craigslist to replace it, or get a shiny new plasma or LED TV instead.

Getting back to my SD Wega (36FS10) - I get it that it might not be able (or even desirable) to enable 480p in the service menu (even if that were possible). Enabling V compression would be useful - has anyone ever seen that as a setting in the service menu?

What I'm really interested in is -> has Sony ever put PiP (enable/disable) in the service menu for any of these Wega TV's?

I have this exact problem. I can't change the geometry of my old 20 inch Sony Trinitron because adjusting the HSIZ value does not change the picture at all. The HSIZ code seems to be locked.

I really need to unlock the HSIZ. Can anyone help me?

I have a KV34XBR800 with a build date of Nov 2002 and I've noticed it recently shutting down while viewing. My initial guess is that it's the two IC parts that seem to be the typical cause of this sort of problem. However, when turning it on, it's inconsistent as far as how many "blinks" the red standby light flashes before it starts up. Sometimes it's as little as a couple up to 9 flashes. The other thing - the last couple times it's shut down, the screen kind of flashes to a near solid red as it shuts down. Removed the back and wound up spending a lot of time thoroughly cleaning out the dust. Checking the onscreen maintenance/status display, this is what I get:

Version 0 0 Service
F/A: 11111111 10111111
CBA: 11111111 10110001

Anyone have any ideas what that means?

i have the kd-34xbr960. im using it for xbox.360 hdmi gaming. i switched hdpt to 0 and input lag went.away, but gave me a picture with part of the left chopped off, flunctuating brightness as stuff on the screen moves, and the infamous vertical right-to-left scrolling bar. i managed to fix the picture position thru the service menu but i still have those other 2 problems. plz help!

.

Thank you! This info helped me too

Hi any service mode tweaks for old sony kv36fs13? I've tried a lot of them.

Oh, please somebody help!

I made my final service mode screen adjustments on my KD-34XBR970 and saved the parameters to non-volatile RAM (+) and within a second or so the screen flipped into a GRID PATTERN and the television started producing a TEST TONE!

Ah!!!

Now when I turn on the set I can see my DVD component input for about one or two seconds but the television immediately switches to a blaring TEST TONE and this GRID TEST PATTERN.

I can go into service mode again but the whole time the tv's blares the test audio tone and the video input cannot be switched.

Any ideas???

I hope someone knows how to adjust this!

The internal grid pattern would have been really useful to know how to turn on when calibrating but now that I'm done I really need it off!

Oh, and yes, I already tried unplugging the set for a few minutes and plugging it back in... it still came up and switched right into test tone mode.

While the service mode works, if I don't choose service mode I can't do simple things like change the volume level. I think I bricked my whole TV.

Sorry for the noise! I found the solution here:

THANK YOU AVSFORUM!

In the blue colored text section -- the QM section -- it's the service code PATN. It needs to be set to 0.

Hey everyone. I'm having some focus issues with my KV-30HS420. The edges are really blurry. I understand that these CRTs all have this to some degree, but I watch a lot of anime/subtitles movies and it is noticeable and annoying. I have used the service menu and made the screen size nearly perfect (as it too was off) and tried adjusting the "focus settings" like QPAM, QPAV etc. to no avail. I know others have posted with similar problems, but I was wondering if anyone else with this set had some service values that I could use to help with this focus issue. Feel free to reply or PM me.
Thanks.

Edit:
It appears that the focus problem extends beyond just the edges of the screen. The text on the XMB menu of my PS3 looks kind of blurry. Are there any service mode values that I can tweak to correct for this (preferably less invasive settings as I'm afraid of bricking my TV)? I would rather not open up this television as I'm not the most technologically inclined when it comes to this kind of thing.

Hello! my tv model is a sony wega kv30hs420 does anyone know how to deal with a wave effect on bottom of the screen? it only appears on hd sources (component and HDMI) but not on 480i or 480p. I've tried adjusting it in the service menu but nothing seems to help.
EDIT: it only seems to appear at 1080i and not 720p.

Im having a problem with my XBR960. There is a layer of static over the picture. This is regardless of source and the static goes over not only the actual video feed but also things like the user menu. I'm worried this might be a problem with something inside the set but does anyone know if this is something that can be fixed through the service menu? I'm really frustrates because I don't want to go through all the trouble of acquiring a new one of these. Thanks.

Hi,

I searched this thread & cannot locate a similar problem.

My 34xbr960 remote has become unresponsive & the set is changing input to memory stick mode while watching TV.

First I thought it was my remote & changed the batteries, but using the manual controls does not help.

Is it toast or is there any solution?

I am watching Sony 40" Google TV but it's pathetic compared tomy XBR.

Can anyone point me to a thread where this has been discussed. Thanks.
