content: I'm replacing the screen on my meter. The connection on the lcd seems to be the same footrint as standard 16 pin DIP. Is there a connector that would friction into such a thing. The hole size seems exactly like what you'd expect if you were gonna solder an IC there. I remember the original cable (which I lost) just press fitting into the old lcd.

content: Maybe one of these headers? You will need to solder on your own cable though.https://www.digikey.com/en/products/filter/rectangular-connectors/headers-specialty-pin/318?s=N4IgjCBcoBw1oDGUBmBDANgZwKYBoQB7KAbXAAYBmAdjHJAF0CAHAFyhAGVWAnASwB2AcxABfAjACcCEMkjps%2BIqRCTqAJgBsjFu0hdegkeJABWTZRlyFuAsUhkwMMJvpMQbDt37CxBdWAaVqiYtsoOIOo6HnogAJICrDhCODx%2BIAC0UdCyULwArkr2ZKaMoibaOXwAJhwZdBC6HCAErACezDgcaFjI5UA

content: I am looking for n something along those lines, but a press fit into the lcd rather than solderingThe LCD has a DIP 16 pattern of through holes, but I don't want to solder into them. You can only get to the top of the holes without wrecking the LCD. I know I can solder pin into these holes and make a cable. I want something with pins I can just push in, and have a friction connection directly to the LCD. This is how the original cable (that I lost) worked.

content: But that's what he showed you...Maybe you wanta premade cable?Not sure what the other end looks like though. Maybe take some pictures?

content: Oh, I think I get it - there is no socket underneath - they are just a press fit into the PCB through holes? Hmmm, that's a bit "how ya doing" from HP. Sounds like you need something like solderless pin headers, also known as press fit (or hammer pin headers, because you can fit them with a hammer). I think that i'd prefer to solder my own socket and use the header that I suggested earlier... or even use a standard pin header and use the common crimp type IDC cable connectors.https://www.samtec.com/products/pht
