HDMI Port only works when pushed down

Hello,

I am having an issue with my PS4 in which the HDMI port has become faulty and only works when downwards pressure is applied on the end of the cable (otherwise there is either no signal, pixels covering the screen, or just a black screen being outputted). This issue is isolated to the port, as I have tried different monitors and cables.

I plan to send it in for repair, but I did have this sent back to the seller less than a week ago and whilst it did work for a few days, it no longer does. This leads me to think that the repair was done poorly.

I was wondering if there was anything I could try now before sending it in for repair. I have a set of Torx screwdrivers, but no soldering iron or heat gun so would not be able to change anything internally.

If anyone knows what has happened or how to fix it please let me know.

Thank you.
