Can I buy individual parts on motherboard?

[Bigzbe318]

Hello, when I purchased this all in one used it was beeping in a way that indicated that either there was a motherboard issue or a power supply issue. I discovered it was not the power supply after buying a new one that was plenty powerful. I went online and purchased a used 24" xa AIO with a broken display but a working board, because on this HP website it showed it had the exact same motherboard with the same display connectors that my 27" AIO had. Upon receiving it it does have the exact same motherboard but there are two models of this motherboard and the one I received from this parts machine was the wrong one because it had the single lvds ribbon cable that slides in and the one I have is the one that has two separate lvds ribbon cables that plug in and are similar to the shape of a sata plug. Well I went on a mission because I had spent so much already that I had to try to make something work and I started taking every component off the back of the board around this chip that was something to do with the display. I can't remember the name of the chip and I'm no pro but have tinkered several hundred hours on various pcbs. So now that I've meticulously moved every single component as they were on the original board including the bigger video type chip that was on my original board, I still need the two lvds female parts of the plug that are just blank spots on my board. Sorry if my writing is not the best and unless you've messed with these two variations of this particular board I'm sure it would be hard to make any sense of all this but I'm hoping there's an actual pro tech (unlike myself) out there that can tell me if I can possibly get these two (HP proprietary I believe) connectors somewhere besides taking them off a board because I messed up the ones that were on my original board lol! A lot of my tools burn up in my shed so I was left with using a piece of wire wrapped around the connector and a soldering gun which eventually messed up one of my connectors and the other one I may can limp it to glory but I'm doubtful!! I don't want to have to buy another board just to hope I can get the right one with these connectors because the last time I did all my homework and seen a picture of the board and everything and when I got it it was actually the wrong board anyway! Also even though these boards are almost identical other than these few components, my board is always over $200 used and the other one you can find for $100 $150 used and I just don't have that to sink into it after what I've already put into it. I would have to cut my losses at that point and sell the screen and part out the rest. I'm thinking about soldering the wire straight to the board and may not have any other way to try. I'll get a pic of the two variations and post here in a few. Oh and one other thing, If I remember right this all in one has HDMI in and outs so I was wondering could I use it for another desktop if I run out of options? I'm thinking probably not without these display cables being hooked to the board I don't know if that's possible Thanks for any help anyone may have.
