I have two of these units bad is there a weakness in these boards or is it typical for the power board to go out ?
Hi, it is hard to say why but they should not go bad often. If it does then it is probably caused by outside source like water, power related problems, other component within the system, etc. If the source of the problem is not fix then the new one will get damaged just as fast if not faster. It is best to have someone take a look if you don't know where to look. Item is ready to ship and you can order from the link below if needed. Thank you.
