My Sansa clip+ won't turn on what so ever

That is unfortunate. Even if it can be fixed, is it worth all the bother? Opening the player, fixing it, then closing the player properly without breaking something in the process is not easy. These players weren’t meant to be repairable. Unfortunately the Clip Sport and Clip Jam are not versatile as the Clip+ and Clip Zip, as the Clip+ and Clip Zip are Rockboxable, and capable of having a huge number of songs in a single database when using Rockbox, and a large capacity SDXC card formatted as FAT32. The Clip sport and Clip Jam are limited to 2,000 songs for the internal memory database, and 2,000 songs for the external card database. These are kept separate. on the plus side though, the Clip sport has 25 hours of battery life listed, vs 15 hours for the Clip+ and Clip Zip. Many people have under 2,000 songs they want on a player though, so for them the limitations of the Clip Sport and Clip Jam won’t be an issue.
