Hello everyone,
quick repair log about how to fix stuck inputs on mv1fz, this one had 3 stuck inputs.

Now onto the fix :

First : gave the board a visual inspection for any broken traces and there weren’t any.

Second : tested the arrays and they gave good readings

Third : traced the arrays to where they go to and they go to the NEO-C1 chip

Fourth : replaced that chip with one from a donner board

and that seem to fix the problem , all the inputs are back to normal.
