Well the title sums it up really. A few weeks ago we leant my colleague a portable DVD player kit, which was returned a couple of lweeks later. Today we reused the DVD player for the first time since it was returned to us, and found that the volume switch was missing on one machine thus rendering the film silent. When my colleague gave us back the machine no mention was made, and we didn't check it over either. So, since we haven't used it since we got it back, I suppose this happened whilst it was on loan, so do I ask my colleague about it, and if so how? Or shall i just leave it and try and get it fixed? DVD player new this summer, and I'm positive it worked when we gave it to her. In fact she was very greatful and said it had been fab. What to do?
