OldFoo · Post by **OldFoo** » Sat May 09, 2009 6:34 pm

i have the following chassis in my net city: toshiba R-1781 with toshiba tube...but i cant enter the extended menu, does somebody here know how i can do this?

i already contacted sega europa and toshiba europe, but both cant help me..... very strange, cause this chassis was (andy geezer told me) in japanese net citys from 2004-2005......

here is a picture of the digital chassis....

sega can't help because they know nothing

i would try holding down the menu button for 10 secs

i tried every possible combination, but without luck.....

now i have plugged a 10k poti between menu (function) and ground....

when i adjust 5k on the poti and press the button, i get the geometry setup onscreen, 0 ohm i get the menu where i can change the colors and when i adjust the poti to 3 k i can change the hsync....

its not a optimal solution, but now i can correct the picture...

i?m sure there must be a button combination to enter the extended menu....

isn t there a little press button on the big board it self maybe? and just to make sure is the controller board the original one?

if this would be so easy, believe me, i would found it

i think there must be a special service control pcb to edit this settings....

the chassis is super rare, i think that must be the reason why nobody has infos about it...

I tried google and live search for this chassis. Two things I found:

The toshiba site provides an email address to which inquiries can be sent for their CRT products:

"For CRT products, please contact with MATSUSHITA TOSHIBA PICTURE DISPLAY CO., LTD at the following mail address: mtpd@sel.mec.mei.co.jp"

And 'startechjournals' has info about this chassis in a repair guide (cost 59 dollars, though..). They classify this chassis as being part of the Initial D3 cabinets:

Table of contents of this guide:

Hope this helps just a little bit..

thanks for the info, i?ll try the mail adress for toshiba..

i already contacted startechjournal last weekend, but 59 usd for some infos is too much for me, and startechjournal wont give any infos for free.

edit: the mail adress: mtpd@sel.mec.mei.co.jp doesnt exists... i got a error msg from my outlook...

what is it you are trying to do once you get access to this menu? Perhaps someone can suggest if it's possible through another means?
