    PCB hole repair or bypass wire tips needed!

    I found a really bad repair on my power board and the hole is scrap.

    When I solder it doesnt stick to the board. there is any tips to repair a hole or can we solder a wire?

    and since it s a negtive lead of the caps can I solder it to any other negative cap lead?

    thanks

    you need to desolder the cap and see what the other side of the board looks like.

      the other side is not really better...I do not see the small ring that we normally see

      I am thinking about wiring it up to a GND pin of the nearest connector

      what do you think?

        without seeing pictures of the top side of the board its hard to say.

                  ok so here some other pic, from under the board, there is continuity between the 2 red circle, so I assume that the solder make a good contact but I do not trust it!

                  picture from the top the red circle is the cap side with the bad solder

                  Can I wire from the bad solder to the gnd with the red circle?

                  thanks

                    You can scrape off the green coating next to the bad hole and solder a new cap to it.
                    Just measure how long to leave the neg. lead of the cap.

                      What is that stuck top left side of the black cap?...the blue cap is hiding the side. Looks like the stuff spewed by a badcap.

                          I finally decided to solder a wire directly to the GND, it seem to work but still have the same problem with the TV....lol

                                    TV flash for 5 min then everything goas A1. Change 3 bad caps and rewired a ground caps but nothing change. I normally repair LCD monitor so I am really lost in this Plasma TV. DOnt really where to look up!
