I get a cd pro2 unit from a guy here,but the MCU (P89C51RD+) is already crashed before.
The VAU1254/11 is not work when I power it on and P89C51RD+ is very very hot ,the laser is on all the time when +5V supplyed.
So the P89C51RD+ programed is needed.
Could someone get the source of P89C51RD+ in the VAU1254/11?
If I had one, take the MCU out of PCB then read the source ......
But I have only one which needs repaired...
Thanks so much...
