Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
Do the navigation buttons (up, down, left, right) on camera work to select language?
OK, have you pushed Enter button located in middle of navigation buttons after selecting language to move to next option?
This is the only way to move forward, try to push enter button bit harder and if it still doesn't work then I'm afraid that button would be defective and camera became unable to use as the basic/ initial setting wizard must be completed to get the camera in normal mode.
Sending it in for repair would cost more than new camera of same specs, however, I can provide you part number of control/ navigation buttons to search/ google it to get price info if you have plan to take apart camera and replace the control buttons.
I just checked the related service manual of camera and it doesn't provide part number for control buttons set, I'm sorry about it. You would be better off with a new camera at this point. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
