Hello everyone, i got this sampler akai mpc3000 with an dead backlight on the display , And what i want to do is to change that display for a new one with a led backlight. I did this with another sampler akai S950 to be exact. But that one had different display 2x40 i bought one from buydisplay.com it had 16 pinout compared to 14 on the older one, main thing i was able to bypass the inverter and use that to light the led backlight.
On this new mission that I am on i can’t seem to find a lcd display 240x64 without a micro controller, cause the micro controller chip is mountent on the cpu board on the sampler. The chip name is Sanyo LC7981 5h2.
I was wondering if it is somehow possible to bypass the micro controller on the new lcd screen or reversed that is to bybass the micro controller on the cpu board?
Ive attached some pictures aswell.
1st is from the service manual of the akai mpc 3000, pinouts from the display to the cpu board
2nd is the sanyo cip pinout,
3rd is from the pinout of a new lcd display,
4th is pinout of the micro controller of the that newer lcd display.
I am noexpert at electronics so i excuse if my queations are dumb.
Hopefully some can point me in the right direction
