Display Technology

If the Touchscreen is not fully displaying the image fully i.e it's off centre, you can press a button combination to realign it.

On the back of the touchscreen you will see 7 buttons as illustrated below. (Dismounting Instructions can be found here)

Please press these lightly with a pen or paperclip in this order: B > A > A > C > C

Once this is complete, your screen will have realigned and can be used straight away.

There appears to be two variants of the Prisma controller. For both, the first button press is B

If the menu looks like this, the sequence is A > A > A > B

It jiggles for a bit then gives you an option of slightly smiling face or frowning face  on screen. Pressing B again select the smiley and you should be good to go again.

If the display menu looks like this, carry on in this order:  A > C > C 

Once this is complete, your screen will have realigned and can be used straight away.
