i would recommend doing a thorough cleaning of the PS4 Pro. Depending on where its located or if its inside a tv stand or dresser, it can tend to not have enough ventilation and cause overheating. I would also recommend getting PS4 Pro Cooling Stand. Im sure it overheats for some other games that you just have not tried. Hope this helps!
That is where the heatgun or hairdryer comes into play! You want to have either a heatgun or hairdryer, and set it on low setting and medium heat and keep an inch away from display so you don't destroy LCD or any components leading the tablet to be useless. And apply until you believe the screen or glue are warming up and loosening. Be very careful with this process or take to someone if you don't feel comfortable doing so which thousands of people do! No one blames them! But doing so warms up the glue/adhesive so it can come apart and you can continue doing what is necessary for the repair. Hope this helps!
Have you tried to replace the battery? There are times when on any device such as computers, phones, or speakers, that no matter how long you charge it for, once the charger is unplugged, the battery instantly dies and only works when connected to a power source. Has it ever been in water or possibly water had access to the battery?
I would recommend replacing the thunderbolt port. The connections to the thunderbolt may have been damaged or disconnected due to yanking or rough pulling of cord originally connected to thunderbolt.
Repair anything that may seem to prevent you from receiving a warranty, such as replacing the screws and any damage that may have looked to have harmed the motherboard. When turning in device, have it looking very clean and you shouldn't have a problem with getting the free warranty! Good luck!
Make sure all the connections to the motherboard are securely in place, there may be times when some of the cables are partly connected and some are not, leading it to not function properly. Also this tends to happen if you tighten the bracket above the cables too tightly not giving the cables a secure fit into the logic board. Also it can be easy to damage the connectors when not being careful, leading the components to breaking or not functioning properly. I always recommend turning off the device and taking out battery before repair, just to be cautious and to help not accidentally fry a component while during operation. It can also occur when people purchase off-brand screens, which tend to be the really cheap priced LCD/digitzer. So make sure you purchased the screen from a reliable company/brand. Hope this helps the situation. If 4 screens are all having a difficult time, it may be the component on the motherboard.

I would highly recommend using Zeiss Portable Tube Lens Cleaning Kit! It cleans up fogged, smudged glass very well! You can order it online or find at Cabelas, there are many products out there, but this is my preferred substance to clean camera glass or lens.
