Lens error, lens won't come out of the barrel
When starting it up the lens won't come out of the barrel and a message "lens error" shows up.
Is the lens part serviceable? Replaceable?
The Panasonic LUMIX DMC-LX100 is a compact digital camera with 12.8 MP resolution, 4K HD video capabilities, and Wi-Fi access. It was released in November 2014.
A whole range of different faults can cause Lens Error, both electronic and mechanical. If it's a mechanical problem there are a few things you can try listed at https://therestartproject.org/wiki/Compa...
If none of those work, realistically, your only hope is probably to look out for another camera of the same model on ebay with a different fault - hopefully you could get one quite cheaply. Swapping the lenses shouldn't be too difficult.
