    ok so i huntted around and found replacemeants no problem........

      It is a transistor or regulator of some type. Can you get the number off the chip? That will help in identifying it.

          i think i have a 7dxr in my pile o boards.
          if you can find the designation on the board i can look at mine.
          probably a mosfet used as a chopper or syncronous rectfier.

                  If you have access to a web server, you can post the pic here. If not, email the pic to admin@badcaps.net. I can post on one of my web servers, and we can try and figure it out...

                      the componeant that had poped a hole in its self is a Voltage Regulator
                      it can be found right next to the ram_ov .sw
                      the coding on the chip is c5001 .the rest is burnt.

                          How to correctly desolder through hole IC?
                          by LearningToRepair
                          Hi!

                          I tried to desolder through I had IC that I wanted to replace but failed. And now I came here to learn what's the correct way for doing this. I tried to use soldering wick but the capillary force kept solder in the hole. With soldering wick I only managed to remove the part of solder that was outside the hole. But the solder that was inside the hole never got out. And of course when I moved on to next pin the solder in previous hole hardened again so no matter how many times I did all the pins there was still solder in holes.

                          Question 1: what would have been correct...

                          PS5 missing voltage after South Bridge Replacement
                          by mike123333
                          I have a PS5 that had a shorted south bridge and 3.3V rail off fuse F7002. I replaced both of the components and I am only getting about a 150 ma draw upon powering (plugging in the board to the power supply). This should be around 300 ma. I cannot find any shortages anywhere.

                          I checked for voltages around the south bridge and seem to be missing 3.3v and 1.8v. where I am supposed to get 1.8V I have no measurements, the 3.3V in one section is measuring 0.5 and the other is 0.965V. These voltages are in standby mode and not powered on, see photos attached. I was wondering whether those...

                          Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
                          by NWArkGuy
                          Well, I will be the first to admit that I screwed up...

                          In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

                          I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

                          I have 2 that I have found and have in my possession. ...

                          93C46 and 93C56 EEPROM
                          by SidneyCanadas
                          I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

                          https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

                          Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...
