+ | ===== Separating the display board from the case ===== | ||
+ | |||
+ | In case you have trouble with the silicone rubber keyboard or with the microswitches underneath | ||
+ | you may want to take display board and case of your Skyper apart. | ||
+ | |||
+ | Another reason to do this may be that you want to clean the display and case from the inside. | ||
+ | |||

+ | |||
+ | Of course you can do this like DK7TD describes it using a small screwdriver. | ||
+ | |||
+ | If you are unlucky you may end up with a display where some lines of pixels are missing | ||
+ | when you power up your Skyper afterwards. | ||
+ | |||
+ | What has happened? While pulling out the display board this way the flexible board connector | ||
+ | atop of the LCD display may move and some pins can get loose. | ||
+ | |||
+ | Should this ever happen there is no way to fix this. | ||
+ | |||
+ | After experiencing this twice up to now (I have modified >20 Skyper) I asked myself: | ||
+ | |||
+ | Is there a safer way to work on the display board? | ||
+ | |||
+ | YES there is one. | ||
