Title: Control board for Pool Robot no longer working
Post by: born2fly on July 10, 2024, 01:54:23 PM

I'm new to the forum. I repair various electronic devices. Recently I received 2 non-working control boards,  built by 2 different manufacturers for pool robots. One board had 2 obvious faults that resulted from overloading. Those 2 burnt components were replaced to no avail. The other board had no obvious damage. Neither of the board's fuses blew.  Both do have a Microcontroller IC that I suspect might be at fault. Schematics are not available. I have spent days going over both of these boards trying to figure out where the fault is.  >:( 

Is it possible for an overload to corrupt the Microcontroller IC? Both customers have told me their 'pool supply guy' has numerous people in need of repair of these boards but after spending so much time trying to determine what failed I can't help but wonder if I am just wasting my time if it is a Microcontroller IC issue.

I think so.
