I have a Temu r36s which I played for months without issues (I replaced the SD card). I made a pause of not playing for a couple of months, and now the console wont turn on. I tried charging it for a day (red light was on), and still no luck. Tried charging some more and now it only blinks red once you plug it into the charger and turns the red light off. I tried the longer presses, reset button, no SD card as well but no changes. Anyone had this experience? Is the only option to buy a new battery? Thanks!
