I have a k300i and when I select the camera it turns on as a black screen then goes straight back to the main menu! Can it be fixed??

The blue screen typically would have a error message on it. I would recommend hitting the F8 key once a second after turning the computer on to get the windows diagnostic menu with choices such as safe mode. If you can select this then try a system restore point to when the computer was working properly. If you are unable to have it start up by hitting the F8 key then you either have a failing hard drive or a corrupt windows.

Use a card reader to download your pics.
Then, go into the camera menu and find "reset"...follow the on-screen instructions. Then, insert the card, go into the menu and find "format"...follow the on-screen instructions. Use the card reader to download from now on.

gateway w350a T-series HDMI power on but screen stays blank...Its just a black screen. Is there a fix for this?

From SP510 camera switched off:
1. Turn dial on top plate to movie mode (selections from the menu screen apply to the mode the camera is set in);
2. Switch on SP510 power;
3. Press "MENU" button on back plate;
4. Select "Camera Menu" from screen if not already on it, using navigation buttons on back plate
5. Scroll down yellow "Camera menu" tabs to microphone picture (below "Digital Zoom"), which may be showing "off". Select OK and toggle yellow tab from "off" to "on", then press OK button.
6. Microphone tab should now show "on".
7. Return to main menu (press MENU button).
8. Return to image screen (press MENU button).
9. Test to see if video now records sound.
10. If is still doesn't record sound, try "reset" from video menu screen (this will reset the movie mode to factory settings, including microphone on).

When I turn on my TV it goes straight to the menu screen. You can still hear sound but no picture. When I try to exit you see the picture for about a second then it automatically flashes back to the menu screen. Even if I try to use the functions in the menu screen it flashes right back to the main menu screen. Very frustrated...need help!

Hey my27my,
What is most likely the cause of this is the LCD is turned off in the shooting mode. To fix this you need to turn it back on in the record menu. Directions on how to do this are on page 59 of your camera manual. I have included a link to a download of your camera manual in case you need it. I hope this helps!

Thanks for the assistance. It is a problem that the mfg will have to fix.

The camera mechanism is probably malfunctioning, and the phone switches you back to the main menu. Get a repair estimate I hope someone here can give you a DIY fix though good luck
