Promethean Board Disassembly Guide/Service Manual

[mr_anthony]

Good morning everybody,

 

Where can I find a service manual/disassembly guide for a 300 Series Pro smart board?

 

On Friday while preparing to replace a classroom board in which the flame stopped functioning with a board taken from a classroom that's been repurposed, I accidentally broke a loose plug which then proceeded to fall inside the board. The plug is for a what seems like a power cable that runs from the side of the board (behind the sound panel) to the top of the board (behind the flame), it's not the USB cable. My job on Monday is to disassemble that section of the board, retrieve the part in hopes of repairing so the board can be used on the first day of school.

 

In the picture enclosed of a similar board I found online, I circled in red and white the two areas where the cable plugs into with the red circle being the area where the plug receptacle broke.

 

Thank you in advance!
