+ | For an experienced user who knows what he's doing this can be the way to go. | ||
+ | But there is some risk in it especially if you are doing this for the first time. | ||
+ | |||
+ | 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? Please keep in mind that Skyper hardware is around 20 years old stuff. | ||
+ | |||
+ | 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 known way to fix it. | ||

+ | 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. | ||
+ | |||
+ | You can fix the LCD to the display board applying a few drops of 2K glue at the positions | ||
+ | shown below. | ||
+ | |||
+ | After hardening for some hours you can pull out the board using a simple smartphone | ||
+ | opening tool at the two shown positions. | ||
+ | |||
+ | One tool is enough - you don't need two of them. | ||

+ | If you did the soldering and the modification on the RF board of your Skyper yourself | ||
+ | it should be no problem for you to get the old microswitches out and new ones in. | ||
+ | |||
+ | For me it was difficult to get them here in Germany. The dimensions are listed below. | ||
+ | |||
+ | I found them on eBay. They are quite inexpensive even if you have to order 100 pcs in China. | ||
+ | In my opinion its a good idea to replace all 4 microswitches even if only one | ||
+ | is faulty. So the look and feel is the same on all 4 keys afterwards. | ||
