Map of test points on the back of a display?
Is there a way to get a "map" of the test points on the back of my display (a 2x40 LCD) ?
Some traces on the connection pads were lifted and I'm wondering if there's a test point somewhere that work as an alternate connection point. In particular, a couple of the Data connections. The traces go under a black rubber disk, and there are a bunch of test points which go under the same black disk.
If I knew where those test points were I could make use of my display :-) Does the company provide diagrams or anything?
thanks so much,
I assume you are referring to the vias on the PCB. In any case, schematics for the display are unfortunately unavailable. If traces were lifted on the PCB, I would recommend purchasing another one and using the designated thru-hole connections available.0
