FSBUS display problem
 

Hello

I have made the display board, with 2 boards and 2 3 segments board.

Now i have the problem, that the number 1,4,5 and 6 is not schowing correct. By number 1 the a and c bar is on, by number 4 the a,f,g and c is on, by number 5 the f, g, b, c and d is on, by number 6 the f, g, b, e, d, and c is on.
The rest of the numbers is correct. And the same problem on both boards.
The problem is on all segments.

Have any have the same problem?

Display Boards
 

Hi,
sorry my Englisch is not so good.
Ok, the 3C Display Controller Boards are very "ticky" !
The Lines in "PS" Or "Gerber" Script are toooo nearly.
You controll the lines and when he has contact....cut with a fine
knife or needle the lines at the long outside.
A Proffessional dealer can make this fine Layouts without Probs.
look at http://www.cockpitsonic.de

Good luck

Hi Uli

I don't understand your answer, if your mean ther is a schortcut betwen the PCB line, i then do not understand why the same problem is on both boards.
I have check the boards for schortcuts and also messaured an everything is okey on the board.
But whey only some numbers an not all of them? Number 2, 3, 7, 8, 9 and 0 is okey, the rest make mistakes.

If there will be a schortcut between the lines, the must also be mistake on all numbers.

a nice miracle,

i suppose you should change the cabling to the segments as follows:

Connect cable to Segment A to Segment B
Connect cable to Segment B to Segment D
Connect cable to Segment D to Segment A

This might be your problem.
Good luck
