Yes ribbon cables can be repaired but it is a delicate job
I would check the conductors with a ohm meter first just to be sure they are broken
Then if the cable is hard wired onto the control panel you have nothing to loose giving repair a try
Extreme care must be taken so that you do not short the conductors to each other
You may blow the control board if you make a mistake
If you have a friend who is an electronics hobbyist, they could probably do it
Taking it to an electronics shop could end up costing as much as a new part
Method 1:
Need a low wattage pencil soldering iron
Solder in external wires from connector to connector
Bypassing the ribbon connector
Method 2:
Scrape off the plastic coating on one side of the cable to get down to the copper conductors. Small exacto knife or a scalpel works well
Then bridge the gaps with either
A. solder/wire (need a very delicate touch because you do not want to melt the surrounding plastic)
B. or conductive epoxy. This is available at electronics stores. Could also use the stuff they use to repair rear window defrosters. Check the lines with a meter to make sure the fix worked, then tape over the repair heavy enough so the cable cannot bend at the fix location |
