Show laser repair - STC 90C516RD+ Microprocessor
« on: December 27, 2019, 07:42:41 pm »
Hi!

I´m trying to pin down a problem with a stairville DJ lase 150. Neither the laser or the x and y motor is working.
The psu around the circuit seems fine, when i pull the ttl control lines from the laser module board the lasers turns on...so something tells me ive got a problem with the microcontroller(allready changed the crystal).

So i want to see if i can get get any response via some kind of programmer, then maybe pull the code from the stc....
I need some advice regarding the usb isp device that will work with my stc(a link to aliexpress), and if someone got more troubleshooting tips.

Cheers!
