Replacement mainboard for Handspring Visor Prism. Having problems with your Prism? Here is a tested replacement main board / motherboard.

Installation Tip: When you remove the back case of the Visor Prism be very careful not to knock the IR transmitter off of the mainboard. You can see where the IR transmitter is located by looking at the outside of the unit ahead of time. Just be aware that the IR transmitter sits right on the edge of the mainboard (right behind the window) and sticks up from the mainboard so it is easily hit when removing the back of the case.

Installation Tip: Do not use too much force when opening the connector on the mainboard to remove the screen. The little latch on the connector is easy to break off which will render the mainboard useless.

Installation Tip: When you install the Visor Prism LCD screen it can be difficult to get the ribbon cable seated in the mainboard connector properly. Try holding the mainboard in one hand with the connector opening facing downward. Then holding the screen in the other hand insert the ribbon cable into the socket. This way the connector will not keep closing and you also will not have to actually try to hold the ribbon cable itself, just the screen.
