    Panasonic su board

    I was taking the white connection off the sc to su boards. The connector came off with no force at all but stuck in the male end. It left all 4 pins closest to the center, and left 1 of 5 toward the edge of it. The 4 pads are gone as well as the outside grounds that hold ti to the board. Me question is where do the 5 pins trace to? Are they a common ground? I cant tell. Pics to come.

          Hey tvtimmy...
          looked at my 50s30 board from tv that I am still working at (very slow as the boat didn't come thru canadian logistics yet... :-( ).

          Anyways, that connector has the four "board side" connections (towards the basic board layout) connected into the 2,4,6,8 pins in the connector). The 5 that you have "missing" connect into 1,3,5,7,9. One my board, 9 has a test pad towards the side... kind of where the "9" is printed on that track. The others pins are soldered to "short tracks" that don't appear to go anywhere that I could "measure" with a meter. I am thinking perhaps they were "anchor pins" ... in your case not anchoring too good ... :-)

          I haven't removed those boards on my set as I am hoping to not disturb things too much cause I don't really know what I am doing... :-) and don't want to break / make things worse than they are.

          Just rechecked things after re-reading and looking at your pictures. I was mistaken about pin 9... it goes to a "short track" also BUT it is NOT connected to the "test point pad" that mentioned earlier. So all those "odd pins" are nothing but anchor pins for the connector.... my "read".

              I have a couple of sets from the 50" that I can also check. Thanks for the heads up. Might get lucky with some gorrilla glue to hold it down. I got this 55st30 with a 14 blink. Guy who owned it said it had a 13 code and bought a new a board,didnt work. The power supply is bad. I checked the 5 fuses and one was open. Replaced it and BANG. Two others blew. Been checking things on and then off the board and cant find anything yet.

                  Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                  by sam_sam_sam
                  I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                  This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                  Hi everyone!
                  I happened several times, in the search for help from the web, to consult this very interesting forum.
                  So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                  Having said that I come to the gist of my post on the forum as the title suggests.
                  For my passion for technology I'm now collecting several...

                  Problem

                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  Assuming...

                  Panasonic P50S30 SC board pins 1-3 Short
                  by SFETech
                  I'm aware pin 3 is ground, but pin 1 is shorted to pin 3 even when not mounted to the machine. It's happening on the original board as well as the ordered replacement board. TV is giving 14 blinks. I'm trying to troubleshoot the machine and thought I'd figured it out when I found a pin that wasn't labeled as ground (Pin 1) shorted to ground, but now I'm just trying to verify if I have two boards with the same fault or if that's how the board is designed and I'm looking in the wrong area.
