The Philips shop is a small, fairly easy to miss shop in Fethiye. If you approached Fethiye from Calis/Akarca, Migros on your left then the roundabout - turn left at that. The shop is along that road on the right, not too far if walking, before the big furniture shop. As mentioned, it doesn't call out "Philips" to you, it's another little shop with small satellite dishes and remote controls for sale - so my suggestion would be to walk along and look in to see which one has the Philips logos inside and also mainly Philips products.
The good news is he is one of the good guys - he was reliable and really good value when we needed him.
