[TenTec] Jupiter Display brightness

[Fernando]

Well, received the display from China today

and surprised it arrived so quickly.

Looks identical with the exception of the

lack of cabling. From the looks of it,

changing the LEDs on the old one entails

the removal of the bezel and tabs. 

Will try it this weekend.
