The only advice I have is to tray and "assist" the lens out when you turn the camera on. Use your fingers to gently attempt to help the lens to come out.
Digital cameras just are meant to be turned into repair shops. So, sending it in for repair really isn't an option.
Here are some other tricks I've learned but have a good chance of not applying to your problem:
- Ensure battery is fully charged. Maybe let it charge overnight. Or, use fresh AA's if that is what it takes.
- Remove battery(ies) from camera and let sit overnight. Retest.
- Attempt a full reset of the camera if available within the MENU.
- Try to turn on without a memory card. Try with a different memory card.
BONUS TIP (WARNING: Last ditch effort)
- As a last resort, when you are prepared to throw it away... wrap it in a towel and and hit it really hard on a hard surface (preferably one that won't be damaged). I actually got a Canon powershot to work again after getting a lens error by doing just this. I could not believe it. I haven't used it much sense, but it still works 4 months later.
Lastly, in the future, consider alternate camera brands. Vivitar is not known for their quality digital cameras. I'm not saying they don't take good photos. I'm just saying you may have a better experience with a Canon, Nikon, Olympus, Samsung, Sony, Panasonic or Kodak. (Yes, there are probably others)
