How can I get the samsung tab to turn on

I'm assuming this is a new device for you. Do/did you see the battery charging icon in the middle of the screen when you plugged it in? If so, great. If not you are having a problem charging your tablet. Most likely either a bad cord, a cord that's pulled out a bit on either end, or an outlet that's turned off or not working.

If the icon was present and indicates a full charge, then simply press and hold the power button for a few seconds and the screen should start right up.

If it worked for you in the past, check your power cord. I've gone thru 3 on mine.

Virgin mobile venture won't start

Take the battery out. Then put it back in. I couldn't find anything that would work but doing a hard reset. Once I did that the phone worked again. I lost everything but my phone works again.

To hard reset the Virgin Venture please follow the instructions below:

Start with the phone turned off.

  1. Press power button until the phone turns on and vibrates.
  2. Press and hold the up volume button until you see the word hello.
  3. Release the up volume button.
    : You will see the word hello on the screen for about 5-7 seconds.
  4. The screen will display the android guy next to an exclamation point inside a triangle.
  5. Press the home button to access Android system recovery screen.
  6. Scroll to and select wipe data/factory reset.
    : The volume button scrolls and the enter/return key selects
  7. Scroll to and select Yes.
  8. The Venture will reset.
  9. Select reboot system now.

Model 1350 will not aquire satelites to operate


During the initial start up of your GPS it may take 15-30 minutes to lock satellites depending on where it is. I would suggest giving it a full charge powering it on then let it sit for 30 minutes. If you are unable to lock satellites still there may be an issue with your unit.

Hope this helps!

How to charge dvd plug in to ac get a red light some time yellow and do you charge with power switch on or off need a manual.

I have seen no rechargeable device that requires the power switch that lets the device function turned on. Often, it is mentioned that the length of time for a full charge will be longer if the unit is in use at the time since the unit and recharging function both require power and if the player is in use, it logically has priority over the recharging function. In other words, it should charge more quickly if the player is turned off.
Unfortunately, Initial's website: is no longer in operation so finding the manual could be a problem. Initial Technology has sold a number of 'turkeys' in the US (we own an Ilo TV) and I think they no longer exist.

Initial setup to operate gps?

you normally wouldnt have to but it is recommended to charge it. if it was tested before it was packaged, its possible it was in sleep mode instead of turned off..if its in sleep mode, it will drain the batteries over time. if its not starting, charge it for a few hours, then hold the power button untill it starts. if that does not work, try a hard reset.

I turned it on and it lit up and then completely died

Question: Why won't my StreetPilot c3xx power on?
Found on the Garmin web site --> Answer: If your StreetPilot does not power on, or if it turns on then turns off, you can troubleshoot the problem by resetting or charging the unit. The reset is a "soft" reset that you can perform in the car; it restores power to the unit, but it does not remove data.
To reset the unit:
  1. Place the unit in the cradle and roll it backwards slightly to lock it in place.
  2. With the key in the car ignition, turn on the unit or put it in accessory mode.
  3. On the face plate of the unit, put your thumb nail in the groove under the Garmin logo and gently pull off the face plate.
  4. With the face plate removed, press the reset button on the right side.
  5. Turn the unit back on. If the unit still doesn't power on, you may need to charge it.
To charge the unit:
  1. Using the provided USB cable, connect the device to the computer.
  2. Reset the unit (following instructions above).
  3. Keep the device connected to the computer and allow it to charge overnight (7-8 hours).
  4. After charging, unplug the unit and power it on.

Turn it on

Here is the page to download a user manual: The screen you speak of is an initial setup screen, if you use the stylus and tap on the screen where the cross is. this will get you started using the device.
