    Westinghouse LD-4680 repair

    I have picked up today this TV and I thought, that it will be most likely an EEPROM issue, because I have found some EEPROMs for sale.
    To my surprise, this TV is the same as the famous 4665 model, with the same exact issue.
    The only difference is, that at the LED strip, they have changed the connectors.
    It doesn't have, that small tab like connector anymore, they have a push in type connector, much better.
    I have figured out, another way of cleaning the ribbon cable, by using a metal brush with the Dremel at a low RPM.

      Re: Westinghouse LD-4680 repair

      Which ribbon connector are you referring to? I just started a new thread for this set. I tried to search for the model number but came up empty. I am stumped on this one.

          The one on the LED strip. It doesn't have the little clip, holding the ribbon anymore.
          It's a push in only connector.

                  Inside the panel, where are the LEDs, on an aluminum strip.

                          If you remove those two ribbons from the mainboard, the TV should turn on(have LED at the front on).
                          Then try one by one, to see which side is causing the problem.

                                  Help identifying connector for ASUS 4090 Strix RGB LED connector
                                  by 5mall5nail5
                                  Hi All -

                                  I had replaced my ASUS 4090 Strix cooler with a waterblock and put the stock cooler on the shelf. Was moving it and snagged my sweater on the connector and pulled the wires out of the pins on the RGB connector. I tried to get them back on but its too small so I opened the stamped pins and tried to solder but its not a good repair and the wire broke on reinstallation.

                                  Looking to replace the connector on the cable side and get pins to crimp onto a new cable. Bought random JST and such but nothing is correct. Can anyone help identify the connector and possibly matching...

                                  Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                                  The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                                  Original T-con:
                                  Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                                  First replacement T-con:

                                  I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                                  tl;dr: minimal electronics experience and my first repair, lifted 8 pads off the laptop display LED controller board when attempting a connector replacement, options are attempting pad repair or jump wiring.

                                  Toshiba Satellite M50-A keyboard connector on LA-A481P motherboard

                                  Hi guys,
                                  i have a damaged keyboard connector on my older Toshiba Satellite M50-A laptop. I know there is LA-A481P motherboard. In attachment pictures there is a real looking connector and i also found a schematic to the connector. But i need help with finding a real electronic part to replace the damaged connector. e.g. on aliexpress (or different page).
                                  It is 34pin connector and the length from pin n.1 to pin n.34 is 26mm. So it means a pitch length is 0.764 mm. I have seen connectors with 0.5mm , 0.7mm , 0.8mm and 1mm pitch length. But not with 0.75. Is it some special custom connector...

                                  by ntec
                                  I am trying to fix a tablet that someone botched the ffc/fpc connector on as circled in the picture. When buying a replacement connector I see the connectors are categorized by number of pins and pitch but how do I determine what mine is to find an exact replacement. Not sure if it means anything, but beside the connector it has written a number 1 on one side and 51 on the other side which is also written on the ribbon flex...
