          These are very basic steps and @mazloum with 337 posts should be knowing this. Check basic requirements of charging IC as@lapfix has suggested such as ACOK,ACDET,ACN/ACP/CMSRC/REGN Etc.

              Where to find a very small fpc connector 0.3mm between 2 pins ?
              by corrize
              Hello, I search this connector (oxydated).
              It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
              I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
              I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?

              Do you know how to find this connector please ? What is the exact name for find it ?

              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!!

              Lg TCon test pins for screen test
              by alltvrepairs
              Hi,
              i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

              Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

              Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

              Appreciate your help....

              Compaq Proliant 1500 PSU - unknown pins?
              by Scruit
              Compaq Proliant 1500 from the mid 90's. The PSU fires up and a green light appears on the backplane, but no POST / no video / nothing on POST card.

              The first thing I did was test the pins from the PSU and I see most pins are labelled quite clearly and I have verified all those voltages.

              There are 4 pins on the PSU that I don't recognize from their silkscreen labels. I was hoping someone here would know?

              Pin labels that I know and check out ok:
              "5" = 5.1v
              "N5" = -5.0v
              "12" = 12.0v
              "N12" = -12.0v...
