    There's an additional two pairs of wire and another ground contact in the connector that needs to be connected... so yeah need special connector and more wire pairs specially shielded for high speed.

          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....

          Cable Repair
          by Patch2
          I have a broken connector (believe it's a 6 pin mini-DIN) on a cable. The metal shroud and all but one of the pins are separated from the cable, and just stuck together for the photo. The other end is an unknown rectangular connector. The cable is for the foot pedals on an Italian made electronic piano, and the company is out of business. Looking for ideas on how to fix it. I have a soldering iron, but I'm not very skilled at soldering, so getting a retrofit for the broken end may be beyond my ability. The other end would be easier to replace, if I could get a mini-DIN cable with the same number...

          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

          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)...

          HP-Pavilion x360 Laptop Dead After USB-C Cable Connection
          by fweonea
          While at university, I connected my HP-Pavilion x360 14-dw0156ng laptop, running Windows 10, to a monitor using a provided USB-C cable. Immediately after this, my laptop's screen turned black and the device stopped working entirely. There are no signs of life such as fan noise or LED indicators, holding the power button does nothing. I've previously used this same monitor model and cable without issues, the cable typically charges the laptop as well.
          I've attempted holding the power button for over 30 seconds, removing and reinserting the battery, and trying to power it on with only the...

          Help me make charger USB C cable with no cc pins!!
          by marce002
          Hi all, please

          I just want to make a "usb c" charging cable from 5V power supply (have cut cable w/ red black green and white pins connected from factory.... i just want to use 500mah max !

          How do I connect this ? if I do not have CC1 /2 physically wired, how to proceed?

          NOTE: an identical new (not cut) USB A to USB C cable charges my phone but not the remote control!

          here is a picture of the remote, the cable to be used and a picture of what are the factory connected pins

          thanks in advance!!
