Does the brissel brush spin at all? Can you feel any suction? Do not place your hand inside the machine. Simply place your palm flat NEAR the bottom of the vacuum to feel for any air. Can you visually see any movement?
Sounds to me like the hdmi port on that specific TV is malfunctioning. I would check the tv. Plug in a bluray player or anything else into that specific hdmi port on your tv and see if it does the same. If the same issue arises then it's the tv and not the ps4
There could be a number of issues. It could be a bad quality charging cable, it could be a bad lightning connector port, or it could be a bad battery. It is most likely a bad battery. Batteries degrade overtime. It may be time for a new battery.
The LCD cable should not be disconnecting on it’s own. If it hasn't been making a solid connect, then its possible the display was damaged by a short circuit. Replacing the display may only temporarily remediate the situation but until you fix the connect issue, the new display may eventually short out as well.
Hey Michael, The televisión sounds like it is experiencing a bad power supply board. A common occurrence is for a capacitor to go bad or fuse or diode or resistor. The only way to determine what component is bad is to systematically check each one by removing it and testing it with a multimeter. If you want to avoid that, you can just skip it and purchase a whole new power supply board. Hope this helps.
