Front light does not turn on

If the device does not turn on or the front light that always illuminated no longer works, it is possible that the power adapter is defective, we can find another compatible one in Aliexpress for example. If we want to try one of ours, we must take into account the use the same voltage and amperage, normally 5V and in some cases 12V, if we use a different one to the original we can damage the device.

Front light turns on but no image

This can be a software problem so we recommend reinstalling the firmware of our model for this we follow the procedure to find and reinstall the appropriate firmware for our model as explained in this guide.

  • Test on another screen and with another video cable to discard a compatibility problem with our TV or monitor.

Restarts, system hangs or slowness

It can be due to several factors that must be deducted depending on when the problem is observed.

  1. Cooling problem due to bad design of the box, something that is see during gaming sessions or if it goes out after intensive use. The only solution is to improve the cooling system by opening the box or changing the heatsink.
  2. Software problem with which it is necessary to reinstall the firmware or Windows as explained in this manual.
  3. Slowness during the use, it may be due to the fact that we have several apps loaded in memory, we can restart and compare or with the Windows task manager or an app manager app to control the problems in use.

NETWORK PROBLEMS, SCREEN, SOUND, CONTROL OR APPS

  • Network problems with poor Wifi range may be due to antenna or software hardware problems, we recommend first comparing on another router to rule out incompatibility with ours. Also reinstall the firmware or restart the TV-Box from Settings> Storage> Reset for Android TV-Box.
  • Screen shows defects like blinking screen, green or other artifacts, try on another TV and another cable.
  • Colors on screen or black, try to activate the RGB mode in the screen settings of the box, maybe your TV is compatible.
  • Shutdown and control, it is possible that you have conflict with HDMI CEC deactivates that option in the settings of the device.
  • Sound problems, we recommend to read our multi channel sound guide first and check connections.
  • Problems with the apps, if our TV-Box was advertised as compatible with Netflix HD and does not comply, you have to claim.
  • Root problems, if you tried root/unroot and the system was locked reinstall the firmware
  • If we can not solve the problem, we always recommend CLAIM TO THE STORE

INSTALL ANDROID FIRMWARE TO RECOVER SYSTEM

In order to recover our Android TV-Box you have to have several clear points before performing this operation:

    1. We need the EXACT firmware of our model, even devices with the same name especially if they are low-cost models can have different hardware, especially the Wi-Fi chip that are incompatible depending on the installed firmware.
    2. We recommend to contact our store and ask for the exact firmware of our TV-Box, share the link here to help others. If they do not help us or ignore us, it is a point in favor to open a future claim.
    3. You also have our SEARCH on the web, if we do not have the firmware published it is that we do not have it.

PROBLEMS WITH WINDOWS MINI PC

  • We recommended not touch the BIOS of mini PCs because we can leave frozen without solution, the critical points are to change the speed of RAM, overclock or modify the GPU. Likewise this modifications don’t should not hang up our device, so we should CLAIM TO OUR STORE and comment that it has stopped working without entering into technical discussions.
  • If the operating system fails, we recommend reinstalling Windows from scratch, the Windows serial number is saved in the BIOS, so we will not lose the license that will be installed directly. You have Windows installation and configuration manuals available on our website.
    – Download, install or update Windows 10 from a USB drive
    –  Migrate Windows from one disk to another in a simple way

CLAIM TO THE STORE

If you have bought a product and it does not work as well as it should, CLAIM TO YOUR STORE, you are in your right and have effective protections, at least you can have a compensation if it does not work partially or does not meet the specifications that were advertised.

  • AndroidPC.es is not a store, the guarantee is managed by the store where you bought the Amazon device, Gearbest, Aliexpress …
  • Manage your warranty with your store or seller directly, explain the problem and ask for a solution. Document this with screenshots and provide everything you can, photos or videos uploaded to youtube. If they ignore you or do not help you, it will give you strength to claim.
  • Many stores have PayPal as their payment method, you must use his protection and claim the money.
  • In the case of Aliexpress, never do a received order confirmation before testing it, then open a dispute and send documentation.
  • If we have purchased at Amazon there is no problem, just return the device.
  • The online stores or Paypal usually fail in favor of the user if the problem is well documented, do not give up.
