No power power does not come on. Cable is working, as I tried it on another device

If you're hearing a beeping sound when you press the power button but nothing turns on, it's possible that the device is experiencing a power issue. Here are a few troubleshooting steps you can try:

1. Check the power cable: Make sure the power cable is securely plugged into both the NS7 and a working electrical outlet. If you have another power cable, try using that to see if it makes a difference.
2. Reset the device: Try resetting the device by unplugging it from the power source and leaving it unplugged for a few minutes. Then plug it back in and try turning it on again.
3. Check the power supply: If you're using an external power supply, make sure it's providing the correct voltage and amperage. You may need to replace the power supply if it's not working properly.
4. Check the internal fuse: If the NS7 still won't turn on, it's possible that the internal fuse has blown. Unfortunately, the fuse on the NS7 is not user-replaceable, so you'll need to contact Numark's customer support for assistance with a repair or replacement.

If none of these steps work, it's possible that there's a more serious hardware issue with the device. In that case, your best bet is to contact Numark's customer support for further assistance.

Fix an Android device that won't charge or turn on If your Android phone or tablet isn't starting, won't turn on, has a black or blank screen or turns on but immediately turns off, try these steps to fix the issue.
First, try holding down your device's power button for five to seven seconds. This usually restarts a device.
Step 1: Troubleshoot your cable, charger, wall socket & case

1. Use the charger and cable that came with your device. To check that the charger and cable are working, try them with another device.
2. Check that the cable is securely connected to the charger and to your device. Check that there's nothing in your device's port, such as dust or lint.
3. Plug the charger into a wall socket. To check that the outlet is working, plug in something else, like a lamp.
4. Check that no accessories, such as cases or battery packs, cover your device's sensors or press its buttons.

Step 2: Troubleshoot your battery charge Within one minute after you've plugged in your Android device with a working cable, charger and wall socket:

• If you see a battery icon, your phone is powered off and is charging. You can restart right away.
• If you see a red light, your battery is fully discharged. If the red light is flashing, there isn't enough power to turn on. Charge your phone for at least 30 minutes before restarting.

To restart your phone, press and hold the power button for a few seconds. Then, on your screen, tap Restart . (If you don't see 'Restart', press and hold the power button for about 30 seconds, until your phone restarts.)

Step 3: Troubleshoot your screen If you don't see a battery icon or red light after you plug in your Android device, the issue could be with your screen.

1. Press the power button for about 30 seconds.
2. Wait about 2 minutes.
3. Make your phone ring. You can call it from another phone or use Find My Device.

what makes you think its usb overload ?

Check your computer's power cable and the power cables to any devices connected to the computer. Make sure all cables are firmly plugged into electrical outlets and into the computer and other devices. If you have an extra power cable for your computer, swap it in to see if your computer's power cable is the problem. Remove your computer's battery, if it is a laptop, and connect the computer to a electrical outlet to see if it will start up. Sometimes a discharged battery will prevent a laptop from powering up. If your laptop still won't power up, remove the power cable, replace the battery and try to run the computer off battery power. Unplug your computer and plug a lamp or radio into the same electrical outlet and see if that device works.
If the lamp or radio doesn't work, the outlet is the problem. Unplug your computer and open your computer's case, if it is a desktop system. Look for loose cables, cards and connections and attach them firmly. Blow out any dust with a can of compressed air. Also, check your computer's memory chips to make sure they are all plugged in and seated properly. Close the case once you are done and plug in the computer. Disconnect any USB devices connected to your computer and try to power up the system. Sometimes a USB device not connected properly will stop a computer system from powering on. Disconnect any new devices recently added to your system. Sometimes new devices will conflict with other hardware within your computer and cause an overload on your computer's power supply. Disconnect any other devices connected to your computer such as the keyboard, mouse, monitor, printer or scanner and plug your computer into a electrical outlet by itself. Check to see if the computer works. If does work, shut it down and connect just one device, such as the monitor. Turn on the computer and monitor and see if everything works. Continue connecting devices until you find the one that is stopping your entire system from powering up. Hope it helps.

Was it working before? HDMI is a weak signal by nature, so longer runs may not be possible. How far are you going (how long is the cable)? Are you running this HDMI cable by many other cables or perhaps in the presence of an electrically noisy device such as an electric motor? Also, make sure if you are trying to hook up a computer or any device not usually meant for use with televisions that it is HDCP compliant. What is it you are trying to hook up? Have you tried other devices? With the same cables? You should also be sure both devices are powered down after the connection is made and then powered on first the television and then the other device. If that does not work, power both down again and power the device first and then the television. HDMI is very picky about many things. You may also have to check if your television set has a software update at the Samsung website. Another thing is that the output device may need you to change it to output to HDMI in the menu. Try hooking up another television with it and then try the other. Post back if you're still having trouble. Good luck.

two things to try

1. try using another usb port ( preferably one on the back of the pc)
2. switch out usb cable with another

Try the follwoing steps, i m sure that it will start working bcoz i tried the same steps and my printer started working:

1. Turn the power to the computer off.
2. Press the power button to turn off the product.
3. Wait 10 seconds.
4. Restart the computer.
5. Press the power button to turn the product back on.
6. When the computer restarts, try the scan again.

• If the issue is not resolved , try some other troubleshooting:
• Connect USB cable directly to the computer and then restart the product and try to scan again
• If the product still does not work , try some other steps:
• Connect the USB cable to a USB hub or a docking station for a laptop. 1. Restart the computer and the product and try to scan again.
• If the product doesnot works after connecting the USB cable directly to the computer , follow these steps:
  1. 1. Reconnect the USB cable.
     2. Try the scan again.
        • If the product worked when the USB cable was connected directly to the computer, but does not work after reconnecting the USB cable in the original configuration, there might be a problem with the hub or docking station. Either leave the USB cable connected directly to the computer, or contact the manufacturer of the hub or docking station for troubleshooting.
     If the product does not work after connecting the USB cable directly to the computer , follow these steps.
     1. Replace the USB cable.
     2. Try the scan again.
        • If the product does not work with the new cable, continue to the next solution.
  Now, if this doesnot work, there is a conflicting USB device connected to the computer
  1. Disconnect all other USB devices from the computer except for the keyboard, the mouse, and the product.
  2. Try the scan again.
     • The issue would be resolved now and teh answer is that the computer might not have sufficient power supplied to the USB ports to detect multiple USB devices. HP recommends installing a USB powered hub to connect multiple USB devices.

Please check in device manager, is it there ?
it's supposed to be under imaging device.

If it isnot there, it's mean it's hardware, it can be orbicam cable or orbicam itself is bad.
In this case, try to reseat the orbicam cable, it's beside power button, you need to open the power cover (power cover is long cover where the power button reside), you just need to remove 2 scews on power cover, it's in lcd hinges. there are 2 cable beside power button, the camera cable is the cable that come from lcd, not from uppercase.

if your orbicam is in the device manager, try to re-install orbicam software. if you don't have orbicam software, you can download it from www.acerpanam.com.

I hope this will help you.
