JVC cd/cassette/radio player (Hobson NE16)

This is brand new in box, BUT IT HAS FAULT. The power switches off after about 15 minutes of playing a cd or radio etc. Asda sent a replacement item and didn’t want the faulty one back (this item). Not sure if someone handy is able to fix this or they don’t mind having to put power back on every 15 minutes! Comes with box and instruction manual.
