What to do if your new LG V40 ThinQ won’t turn on

To be realistic, if your new LG V40 ThinQ won’t turn on out of the box and won’t respond to its charger after several attempts, then put in back into the box and bring it back to the store and have it replaced. New smartphones should be working out of the warehouse as they’ve been tested prior to shipment. But there are times when problems occur that’s why there are units that may not work but that’s very minimal in numbers. However, you may have gotten a defective one so don’t do anything to it but return it to the store.

On the other hand, if you’ve already used it for a few days or weeks and then it suddenly won’t turn on or respond, then it could be just a minor issue with the firmware provided the phone hasn’t been dropped or got wet. In this case, you have to do something about it since you knew in the first place that it was working. That’s the purpose of this post. I will walk you through in troubleshooting your new device that would no longer power back up. So, continue reading as this article may be able to help you one way or another.

How to troubleshoot LG V40 ThinQ that won’t turn on

We are going to troubleshoot your phone just in case the problem is minor but that doesn’t mean you don’t need help from a technician. What you can do on your end is basic troubleshooting using the solutions that have been proven effective. However, after the troubleshooting and the phone still won’t turn on, then that’s the time you have to seek assistance from the tech. With all that being said, here are a couple of procedures that may help you make your V40 ThinQ respond again.

Forced restart or soft reset – in case you don’t know yet, a forced reboot is a simulated battery removal procedure that will refresh your phone’s memory and reload all apps and services in one go. It is only performed on phones with non-removable batteries like your LG V40 ThinQ. Your device should respond to it as it’s hard-wired to provided that the procedure is done correctly and this is how you do it:

  • Press and hold the Power button and Volume Down at the same time until the device powers off, approximately 8 seconds, then release.

If the phone boots up after doing this, then that’s the end of the problem but if not, try doing the same procedure a few more times. After which and the phone still remains unresponsive, then try this:

  1. Press and hold the Volume Down button first and don’t let go.
  2. Press and hold the Power key while holding down the Volume Down button.
  3. Now, keep both keys held down together for 8 seconds or more.

It’s basically the same as the first but this time we’re making sure that the power button is pressed and held after the volume down key because doing it otherwise won’t give you the same result. However, if your V40 ThinQ is still not responding after said procedure, then here’s what you should do next.

Charge phone and do the forced reset again – a drained battery may seem like a very normal occurrence when you own a smartphone but the thing is, there are times when it would lead to a firmware crash. Sure, a problem like this can be fixed by a forced reboot but if your phone doesn’t have enough battery, then it still wouldn’t respond as it couldn’t power up. That could even be the reason why it didn’t respond when you did the first procedure. So, here’s what you should do about it:

  1. Plug the charger into a working wall outlet. It’s important that you use the wired charger for this procedure.
  2. Using the original power / data cable, connect the device to its charger.
  3. Now, regardless whether the device shows up the charging signs or not, allow the phone to be connected to its charger for 10 minutes, at least.
  4. After which, press and hold the volume down button first and don’t let it go.
  5. Now, press and hold the power key while holding down the volume down button.
  6. Keep both keys held down together for 10 seconds or more while the phone is still connected to its charger.

If the problem is just a minor one caused by a drained battery and system crash, then your phone should already be booting up by now but if not, then it’s more serious that we initially thought. So, it’s now a perfect time to bring the device back to the store so that a technician can check it for you.
