You could always contact Sanyo
...and get grey hair...I know
I've tried to get pinouts for a different LCD.
Their reply was:
" LM-HB53-22NEK :Unfortunately,
The type number LM-HB53-22NEK is not included in our product line. It's thought to be provided by other manufacturer."
Well the label on the backside says Sanyo as far as my eyes can see...
Here are some webpages that may help though:
www.eio.com/public/lcd/0120.htm
or
www.eio.com/public/lcd.2001/0893.html
and finally:
Sanyo's different homepages
Good Luck!
