[TenTec] Jupiter Display brightness

[k4mt1950 at charter.net]

Does the ribbon cable from the display to circuit board unplug at the
main board? I have looked but afraid to pull on it.
Unsoldering those pins on the display board might be a challenge
without getting too much heat on the ribbon cable.

 Not to monopolize the thread, here is what

 I found in my Jupiter.

 The voltage regulator supplies 5V to

 parallel resistors, then 4.5v to J12.

 When I put 5V directly to J12, the backlight

 brittens up a bit but the graphics is still

 dim. So went ahead and ordered a new display.

 However, the new display looks like it

 won’t come with a connecting flat cable (FFC).

 Question to arGy, did you have to unsolder

 the 20 or so pins from the old display cable to 

 then to the new one? Or did your display

 come with a cable attached?

 BTW,, the R133 Contrast control is a coarse

 adjustment, and sensitive too.

 tnx..
