Hi All,
Just bought an MPU4 Hi Jinx machine. When switched on display didn't wor, so tested on mpu5, still didnt work. Bought new display off ebay, tested in mpu5 machine, works fine. Put in mpu4 wont work. Checked voltages on connector. Red is 12v, Orange im guessing is for 5v as it is on mpu5, but on mpu4 doesnt show any voltage. Any ideas what might cause this? Any help appreciated!
