When you are satisfied that the wire has been wetted to the trace and does not contact any adjacent traces, place the tip of your X-Acto blade on the wire at the point where the solder joint ends and GENTLY press just hard enough to score the wire. Now wiggle the wire and it will soon break free of the now repaired trace.

Repeat as needed to finish your cable repair.

After you are done, and have made continuity checks to insure there are no solder bridges between adjacent traces, it would be a good idea to place a layer of flexible adhesive/sealant over the repair area. RTV silicone is a choice, and so is hot melt glue in a pinch.


I hope this helps you out.

Indeed that is tricking, i've had simiiliar problems. But for anyone else needing to so such a repair. I suggest using the wire that comes out of those cheap earbud headphones. they have a very flexible wire conductor. its coated with some layer to keep it non-conductive. Just tin at ends and attach at points needed to connect.

isnt it just possible to soldier normal wire to the PCB where the flex cable normally plugs into the socket thing? Just to reconnect the trazks on the flex that are broken?

I did this with the flex on a mini tv i was playing with, infact i got rid of the flex all together and cause i totally messed it up and just soldiered about 12 wires instead of the flex

sorry about my bad use of words, i dont know what these things are called
