    I guess, at this point, I might as well take it off and see if the short is gone. If I use hot air, I am assuming this board would be safe, correct?

      either that, or you can cut the legs off with a knife and get rid of the leftovers on the pads with solder wick.

        Well, I finally took out the main chip (the burnt one)...and the short went away!! I guess that was the problem.

        Now, how/where do I find this chip to purchase? Can I use another chip?

        any ideas?

        thanks

          best idea I can come up with is to look for the IC on Aliexpress or some other china mart, or look for a "universal lvds board" and convert the TV.

            Budm cited a site that has a main board available, but they want a hefty $65US plus $25 shipping. At this point, I'm unwilling to put in $90US into this tv.


            I found this site that has three ic numbers for the same chip. Are they all compatible??

              There are many sellers that sell that chip. So specify the one you need to the seller, or look for a different seller.

                After buying from a seller from Aliexpress and paid through paypal over a month ago, I still did not receive this chip. I eventually had to open a dispute through paypal and got my money back.

                Back to the drawing board to get this chip.....still looking.
