Hi All
I have been thinking about how to fix the broken pixel in the BL5000 display. Last week I found 2 BL5000 in very bad shape, however, the display was working, but with the usual pixel errors. I decided to find out if it was the display, or the connection from PCB to LCD that is the problem, and in the 2 displays I have, it is the connection via the white ribbon that is broken... It is the carbon traces that crack over time and cause the pixel errors, NOT the display itself..
Found this guy :
http://www.instructables.com/id/How-to-remove-and-re-attach-LCD-Ribbon-from-a-PCB-/
What he is doing is just what I would like to do, however I need to attach the new ribbon to both PCB and LCD.
So I decided to try some tests, and it is only the connection that was the problem, I could actually get the display working 100% without any pixel errors by folding and stretching the ribbon at different angels..
Now all I need is to figure out if it is possible to buy the ribbon somewhere, it could be wider, however just need to find a ribbon with the correct spacing..
Anyone have some input on where and if it possible to get a hold of these ribbons ?
Here is a picture of the ribbon detached from the LCD
And the ribbon removed from PCB
And the display cleaned from the glue from the old ribbon. Before I removed the ribbon from the PCB, I tried to just hold it against the cleaned display, and it works, however it impossible to get connection on all points, but there was life in the display :)
