i don’t know if i have to solder something or get a new hdmi port and solder it.
If the problem is truly and HDMI port problem and the port is bad the only way to fix it is to remove the port and install a new port. This requires soldering. If the HDMI port is not physically damaged then you may have a hard drive problem. Many times when there is just a black screen it’s a hard drive problem. Hope this helps.
