laptop Solder HDMI into Laptop?

[Finnean]

I have an old Toshiba Satellite C875D-S7101 from a few years back I am thinking about stripping it down to make it a theater PC. Unfortunately, it does not come with HDMI. While it does have all the solder points for an HDMI, it just doesn't have the port. Is it at all possible to solder in my own HDMI port into this slot, or would it just not work. Also, if I can't do this, can I take out the main display  cable going to the built in display and solder it in to an HDMI cable. I just can't bear to use VGA in this case.

Yes as long as the wire is correctly powered for HDMI and make sure you follow the pinout correctly.

Soldering to the monitor cable is not possible, as it is LVDS not HDMI.

 

As for the HDMI pads, you'll need to be very good at soldering. Probably a 0.1mm tip and fine solder with some additional flux. Thats if they are even connected/work. Make sure to compare the recommended pcb footprint to the pads on the laptop PCB to ensure it can be soldered in at all. Just buying a random connector will create an utter nightmare if the pads are not the same. Mounting it to the board with trailing wires will be next to impossible.

 

If you can't solder 0805 smd parts, I would not even bother attempting this.

Thanks so much for the response. I think I will just find a VGA to HDMI adapter along with USB for audio, or scrap it all together.
