So I have a n3dsxl which is homebrewed and the top screen was broken, the bottom left corner was filled with dead pixels so I decided to change it, I saw some videos and felt prepared and I switched it with an extra LCD screen I had for the n3dsxl after I did everything I put everything back in place but after I turned it on no matter how many times I lowered the volume it stayed on max as well as the 3d and i made sure that the slider was actually moving the volume switch and the 3d switch and still nothing so i decided to change my 3ds speakers with the spare parts i had and then when i turned it on the screens stayed on black made a popping sound after flashing a white light then turned off afterwards I reverted back to all my original pieces of my ds and now when i turn it on the blue light turns on for a moment and it stays on a black screen for a moment then the bottom screen flashes white and then shuts off i dont know what to do now all the cables are going to the right places and i made sure of it and the camera stayed intact, I also saw a video that when switching screens from TN to IPS you had to download a software or something of the sort and i asnt to sure if i had to do that with mines because the top was an IPS and i switched it with a TN screen. Any help would be great, Thank you for reading my long post.
