Sony HDR-CX105E Camcorder - Black

Hello, The camera arrived quickly. It didn't come with a memory card (I'd asked if it was included in the purchase), but I was able to sort it out. However, it no longer works... After only a week. The charger works fine. It's the screen with the camera/photo feedback... Nothing works, it lights up, but is grey. In the hope that my opinion will be useful to you and that you will have a solution to propose to me. Thank you very much.
