IMPORTANT:

When assembling/disassembling the main board, whenever there is a mylar on the main board 

(see the highlighted with red below; the mylar is sami-transparent, film-like stuff ), it should be 
transferred “if necessary” to the replacement main board. Because the main board mylar should be 
stuck to the main board to prevent the antenna cable and the main board components short circuit. 
The short could cause the main board or the antenna cable burned.
