H80 ADDR Codes

<< Back to Service/Designer Menu Page

Starting with the H80 generation sets, Toshiba has locked out the Designer Mode.   For the calibrators and ultra serious tweakers, this is a major drawback.   Brave souls like Stephen Smith, and DougH, and Tom Herman however have been able to find a workaround, sort of...

Tip from Tom Herman:


The following info is to be used at your own risk, I'm not responsible for errors!

Your TV could get REALLY hosed & rendered inoperable, working from within ADDR mode.

As some of you may know, ADDR mode is an arcane menu
on the Toshiba TVs. Instead of mnemonics (like RCUT, VPOS) as found on Service & Design Menu, ADDR mode has only unnamed hexadecimal addresses (000h-FFFh) and hex data values. ADDR mode is believed to be a superset of Design Mode, just as Design Mode is a superset of Service Mode.

Some brave souls have figured out how to use ADDR mode to change width and color of the TW series' side gray bars (in 4:3 mode).  Others have made a 1 to 1 correspondence between Design Menu & ADDR mode; Bruce Pope recently offered a spreadsheet mapping the TW65H80 Design Menu to its ADDR values, for example.

As many of you know, 2001 Toshibas don't have Design Menu accessible .. a common thought is that it's still there in some form, but with a different access code.

ADDR mode, though, is still accessible, using a Cinema-7 universal remote. Once the Toshiba is configured into the Cinema-7, then the keystrokes "SETUP 0 1 4" put the set into ADDR mode. Pressing "EXIT" on Cinema-7, exits the ADDR mode without needing to power off the set. "CH up/down" scrolls thru the various ADDR locations. "VOL up/down" changes the data in a location.


"SETUP 034" and "SETUP 093" will cause resets of the TV's settings, possibly rendering the set inoperable. Other bad things could happen by mindlessly pressing keys.

Several people have been pursuing the possibility of working around the lack of Design Mode access, using ADDR mode.

DougH posted at Home Theater Forum, and he's found the ADDR location of STC1-STC6 in his 40H80 set. STC's set the vert & horiz Static Convergence for each color CRT, and are ideally set to 80h before doing a mechanical centering of the picture (with CRT magnets). 

Thanks, Doug! I especially wanted to have the STC codes made available. I've been holding off on a geometry fine-tune until these were available. 

I've compiled an Excel spreadsheet of all the ADDR settings for my 65H80, and I can email on request. I don't know what the vast majority of ADDR data corresponds to ... a "Rosetta Stone" is lacking.

I do know that this year's ADDR Mode locations, do not match up with the TW65H80 set (and probably not the TW65x81 set, either). This suggests that the 2001 model's Design Menu, when it is found, may have a different form & structure than previous years.

The few ADDR locations I feel fairly certain of are:

ADDR...Equiv Design Code

240....PHUE ?
51B....CNR ??
C0C....PYOF ?
C0D....PIOF ?
C0E....PQOF ?

But since these are already accessible thru Service Mode, doesn't do us any good.

Below are the useful ones DougH found, not previously
accessible in any 2001 year Tosh:

ADDR...Equiv Design Code

257....STC1 H static convergence -Red
258....STC2 V static convergence -Red
259....STC3 H static convergence -Green
25A....STC4 V static convergence -Green
25B....STC5 H static convergence -Blue
25C....STC6 V static convergence -Blue

By making the ADDR list available, I'm hoping some of
you will be smart enough to figure out more of it! My brain is going to be "mush" for a while, after compiling it.

Note that many of the settings are likely to be specific to my specific set. I've also included a list my Service Code items (accessible), but not of course Design Codes (inaccessible).


Another hassle in decoding Service-to-ADDR mode, is the sheer size of ADDR mode locations .. 4,095 (000-FFF hex). Hundreds of the locations seem empty, though ... large blocks of data are just "FF" or "00".

It doesn't automatically scroll thru ADDR locations when you keep the CH button depressed, a separate button press is required ("Ninentendo thumb syndrome"?). Fortunately you don't have to start over when power is turned off, it "remembers".

Since there are only 38 Service Menu items, changing ALL of them & searching for changed ADDR items may be one way to quickly identify the corresponding group of ADDR items.

Alternately, simply changing each ADDR & looking for a corresponding picture effect could help decode ADDR mode. 

Regardless, very tedious ... one would have to look for effects sepataely within Svideo, 480P, 480I, 1080I, TV, the different color temps, all the combinations thereof, etc etc. "

Tip from Stephen Smith

"I have all the designer params mapped out to their corresponding ADDR registers for my TW56X81, along w/the same for Cheezmo's TW65H80. If you've already downloaded this ( spreadsheet then you already have it, but it's hidden by default (too many newbie emails...). To see it, just open the spreadsheet and press CTRL-SHIFT-R. A new Registers page will appear.  

It ought to help you at least some, but you'll notice that there is not much in common location-wise b/t the X81 and TWxxH80, so the same probably goes for the new H80 series. You can see that this menu is organized into distinct register groups with each group starting at some even hex address and separated by from the last by some gap of "empty" FFh registers. It will obviously be harder for you guys to find your designer menu registers w/o the actual values as a reference, but I bet many values are the same b/t the H80 and X81 so you can look for similar patterns.

When I was messing around in there I noticed this: directly adjusting the register for a designer menu param had no effect and did not update the value for the corresponding designer menu param. The other registers had some effect, as did the few unmapped registers that can be found inside the various designer menu groupings. I didn't try that many designer param registers so maybe I'm mistaken. Do yours work? The STC's at least?

I also tried to divine some insight into this menu by downloading the documentation for the various Toshiba IC's in my set, but I couldn't find any correlation b/t the designer params or the ADDR menu and the adjustable I2C parameters described in the docs. Oh well.

Tip: use the 100, 0, and ENT remote buttons for quick navigation around the menu! 

And please send me your ADDR lists and I'll add them to this page."

Tip from Doug Hynes:

"I spent a few hours the other night scrolling through a bunch of values and carefully making changes to see if I could find the graybar settings. I ignored FF values and 00 values (figuring that the graybar stuff wouldn't already be zero). I certainly didn't try all values but tried to change all bits within reason.

Needless to say, I didn't find what I was looking for.

One thing that might be of interest is that some of the service mode settings (HIT, WIT, VPOS, etc.) definitely start at 0x500. I didn't bother to map them out (since you can already get to them through service mode) but there were obviously values for various screen modes. This didn't help much because everything above those values was FF, so it didn't really help locate other possible values.

I did stumble across some values in the 200's that seemed to change brightness or contrast. Like a dummy I didn't record them.

I probably don't need to remind anyone here, but if you're not very careful when trying changes, it's easy to forget where you started. And of course, you won't know what you changed or whether it matters.

About the only other thing I have to add right now is that if you unplug the power, you'll reset the address to 0, which can be helpful sometimes."

More info from Tom H:  "By sorting the "Data" values in the ADDR list, I can see that some values are never used.

Temporarily changing Service codes to one of these unused Datums, should speed up the "needle in a haystack" approach to finding the cross-ref between Service codes & ADDR codes.

For anyone wanting to try this, I suggest sticking to the lower numbers .. higher numbers sometimes produce weird or worrisome effects .. possibly not a good idea if it results in excessive brightness or if it does weird things to the control of the electron beam in the CRTs.

In my set, the unused ADDR data values were (probably varies by set):


Navigation Tip

Per Tom H, "because there are 4096 ADDR locations, scrolling using the "CH Up/Down" button gets tiresome, fast.

Steve Smith reported a quick navigation trick, using the Toshiba remote:

  • "100" button scrolls upward the 1st Hex digit, e.g. from 912 to A12.
  • "0" button scrolls upward the 2nd Hex digit, e.g. from 5C2 to 5D2.
  • The "CH Up/Down" button, of course, will scroll the 3rd digit up or down."
