JVC GR-DX25EK camcorder
JVC has issued a notice on many models that bring up a "lens cap" error. However, the GR-DX25EK is not included. The model you have posted on its page(GR-DX95) is though.
This problem is still very common with models that aren't on the said list, given that and the fact that your model is from the same series, you might get some consideration from JVC. No harm in trying.
The listed models get a free repair.
Heres a link to the notice from JVC:
