So after my brother killed my land cruiser by leaving the headlights on overnight, jumped it and got it started again, everything’s fine except my radio (Sony CarPlay) won’t start up again. Screen won’t turn on, no power from the usb charger on it. But everything else in the truck works: cigarette lighter, all ac controls, buttons, gauge cluster. The fuse is fine in the “radio” spot and I’ve even tried putting new 10A fuses in but nothing. So I’ve unscrewed the radio and now I’ve got the back exposed. I know nothing about wires so can anyone tell me what my next step should be, what I should test or do? I have no clue what I’m looking at, but the only thing that looks a little funky to me is this ?ground? On the right side seems kind of out of place and it almost came out. It’s not being held in by anything, I’ll circle what I’m talking about in the photos. FYI it’s a 94 kzj78 prado
