Need advice about gpu connectors

Hi everyone. I ask for your advice (thanks in advance). A friend of mine rage punched his pc and broke the hdmi connector (visible damage). Asked me to repair it but I advised him to buy a display port hdmi adapter because his monitor only have hdmi and that's cheaper than repairing the port and more straightforward. Then now a few months later he ask me to repair at least one port because he did the same with the other two. There is no visible damage on the dp ports. I fear that replacing a port would not resolve the problem and I need advice on if should look on other components to find the damage. Thanks
