Heres what I have. 
Any ideas?

VAC-fluorescent displays do not have a very long life.

You may be lucky. See if you can read the chip number on the back of the display.

It ISN'T an LCD, its vacuum-fluorescent display, and it probably needs something like 90 odd volts to make it work.

YIKES.. where is that located you think?
The square black blob on the board.

Other than experience, how can you tell it's a vacuum-fluorescent? I'm curious. It looks like a pain to drive.
If you couldn't already tell by just looking at it - a VFD is quite thick and made of glass, like a vacuum tube, then sniffing with a meter would find a supply of somthing like 45 volts on it. Then of course, the chipset is a dead giveaway too.

Its easy enough to drive. Send commands to each element via SPI - no sweat.

It says on the back of the screen :


Made in the philippines, "
M35500A ????

says that yeah. M35500A

Mitsubishi symbol too.
Then you need the datasheet for the part, and you can work out how to hang the thing either on SPI bus, or bit-bang the interface. You'll probably find someone else may have written a driver.

Im really a noob with this thing haha so I dont really know how to do that :|
This is how you stop being a noob. You have to start somewhere ;-)

:| I think thats a wee bit out of my league..
Anything like "M66004" on the blob ?
