Create 2 won't charge

Postby rafaelmarinhoa » July 28th, 2017, 5:11 pm

I had an accident with my robot and some SMD stuff got corroded arround U8, though the IC seems to be fine. I managed to replace the resistores since I found their value, but I wasn't lucky with the capacitors. Could someone tell me what are the values of the capacitors C112, C125, C113 and C89.

By the way, I'm getting charging error 3 and 2, but i'm quite sure the capacitors are faulty.

I tried to measure their values but was unsuccessful. I kept loosing the LIBDs.

I think the board can run without some of theese capacitors. At least for some time. Is there any guide for testing the board? I could try to guess the value based on the readings. Maybe I'll just replace than with 104/103 ceramic capacitors. What do you think?

Sure, it will run with U8 totally out of wack, except A2 of U8. Won't charge correctly.
