However, the replacement module requires some minor modification prior to installation. One OB-12 owner has offered to may me (Oliver, not Matrix) to prepare a module for him to install, as he doesn't want to do his own soldering/de-soldering. I thought I would offer the service to anyone else who may be interested. I am charging $50 Australian dollars (+ costs) for my service. If enough people are interested, then there would be some savings on parts and combined shipping from supplier to me.
Cost for a single module from futurlec U.S.A. is $US65, plus $US14 shipping to me. I think combined shipping for more modules would still be $14 total, shared between participants. I will supply wires and connectors at my own cost, from my $AU50 fee (it's just easier than accounting for their costs).
If anyone would like to do this work for themselves, instructions will soon be available at the 'Friend's of OB-12' Yahoo! group.
What's involved in the LCD module replacement:
Basically I will prepare a module with my own custom modifications, and send to participating OB-12 owners for you to install in accordance with my included instructions.
From me:
- Purchase LCD module, shipped to me in Australia
- Solder custom 19 pin header onto module board
- Desolder back light LED supply power resistor from bottom side of board, and re-solder to top side of board, to allow module to fit in OB-12 case
- Construct LED back light power supply lead/connector
- Solder LED back light power supply lead to module board
- Test your new display in my OB-12
- Ship display and installation instructions to OB-12 you
From OB-12 owner:
- Email me, or contact me through 'Friend's of OB-12' Yahoo! group, BY NO LATER THAN NOVEMBER 1 (at least for first batch)
- Provide postage details, so I can provide postage quote
- Make payment to my PayPal account
- Receive display in post
- Install display according to instructions. Installation is straight forward, requiring just a Phillips/Pozidrive screwdriver
- Get back to me via email, if you require further support

"We have now another option for replacing the display which will allow to control the contrast:

"This is the new display type for this mod:

With this display, you will need to modify slightly your ribbon cable. Cut pins 4 and 20, connect to 10k ohm as described. For Ground -connect to the white wire of the LCD backlight (yellow is +, white is ground)"
Hope you will find the video useful."
