1571 with red and green lights always on and motor never stop..

Post by mauro72nob » Sat Aug 04, 2018 12:22 am

Hi..
I have two 1571, both with the same issue. Power on and red led and green are always on, and the motor runs continuosly. Check with different power supply and measure it, the 5v and 12v is correct.
With another 1571 ICs parts, change the u1, u2, u6, u8, u11, u12, u14, u15 and u16 and the same problem. I have replaced too the electrolitic capacitors.
I'm suspect the reset line/clock, any help? Another IC to change and test?
Thanks in advance!

Check power supply voltages first! Do you have a multimeter or tester of some kind?
The price one pays for pursuing any profession, or calling, is an intimate knowledge of its ugly side.

Hi,
Yes, voltages are ok. And tested in another two 1571 and working perfect.
