    Rca led65g55r120q lvds ribbon fubar

    Working on a RCA 65" had a bad LED on one strip. Fixed that, but in the process of re-assembly I FUBARed one of the LVDS ribbon connections that go from T_Con to panel driver board. Its a KaiQun E356155 80 connector ribbon.


    How can I repair this as I am having a difficult time finding a replacement ribbon long enough. Thanks.

    I think you either get a new panel, or you are SOL on that one, unless you have a tab bonding machine.

        No it wasn't a tab bonded cable, it runs from T-Con to panel driver board. has flip connectors at each end.


        So I searched the internet and found a ham radio site where a guy had done about the same thing as I did, but on a fewer contact ribbon. His was long enough as was mine to cut off the fubared section. Saving the blue connector support, it was held on by heat sensitive adhesive.


        Then ribbon was taped down to a flat metal surface, then the next step was the most time consuming part. I took an exacto knife and scraped away the insulation covering the traces a little bit at a time.


        Took about 25 min because I did not want to scrape too hard, got to where the traces were showing then took 320 grit sand paper and finished polishing traces. Sanding with the direction of the traces not across. Finished trimming sides of cable to fit in connector so tab would close, And WALA it worked.

        Didn't post a before pic but 1/4 of left hand side of screen was black before repair on cable.

                A couple on that page for 13 bucks, not cheap but I guess it's supply and demand at work: https://www.ebay.com/sch/i.html?_fro...acat=0&_sop=15
