This listing is for parts/modules we are looking into setting up a repair service for, but require additional research to determine if we are able to properly service them.You must add a note to your order providing the model number of the device, part name and part number of the board or boards you are sending in. This listing fee only covers the cost of testing and diagnostics. Repair costs will be quoted once a proper evaluation of the part/module you send in has been made. Because this is a generic listing we can not predict the weight and size of your device/circuit board. This means the shipping fee you paid is incorrect and will need to be adjusted. Attention: You must ship us your original defective board for us to repair and return it. This is not an item for sale, it is a repair service.
