I have a pair of 2005 Master Replica Sabres and the Vader version has lost its sound.
It 100% used to work, but the last time I switch it on, the batteries had clearly died as it was very dim.. But since then, only the light works and not the sound.
I have tried opening up the electronics module several times, but its clearly glued and I am going to destroy it..
Does anyone have any tips on how to get inside? And if so, are there any known failure modes and obvious components I could replace.
