How do i fix the screen turning on and off on its own

Your lens must be stuck? Usually lens assembly has to be replaced. Easier and cheaper to buy a parts camera of the same model with a bad screen from ebay and fix the parts camera with your good screen from your camera.

I have the same problem but mine turns to a black screen. I have no idea how to fix it. My phone is still like that too.

The screen turned to the sidewards.. This issue can be fixed..

Try these steps

Press and hold the keys Control+ALT and then use the arrow keys and change the screen view.. The issue can be certainly fixed

My ecoquest fresh air turned off suddenly... when i turn it on again there is no power it keeps flashing in the front screen .. is it an easy fix or hard fix ? please advice ... thank you

The cable that connects the screen to the phone is damaged, causing it to white screen. Other than sending it back to the manufacturer or having Nextel fix it, there's no fix other than for it to be swapped out.

Try this fix....

Hi. You can get tech assistance straight from Samsung by going to:

There are three levels of fixes, please try them in order:
1. Reset the GPS using the Reset button, on the back, just under the Antenna Hinge. Resetting will turn off the GPS, and then turn it back on, if connected to power. Test, if fixed, great, otherwise, go to fix 2.
2. Turn the power off, then press and hold the powerbutton for up to 2 minutes. The GPS will turn on, and display a "PreBoot Mode" message. When that message disappears, and the screen calibration screen appears, follow the on-screen instructions, and you are fixed. If you still cannot use the touch screen, repeat fixes 1 and 2 several times, just to be sure., then go to fix 3
3. The touch-screen glass has probably broken or lost its connection with the GPX motherboard. You can order new touch screen glass on the web and install yourself, if you are techy in nature, otherwise do a search for "garmin nuvi 660 repair" and choose your service.
