Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
What is the exact model number of your phone ?
That IMIE helped. It is a Lumia 435 model. This usually happens if the firmware is glitched and in some cases issues with battery can also cause this. First we can soft reset the phone and see if it works or not.
Press and hold down the Volume Down and Power at the same time for 10 seconds and this will soft reset it. If that didn't work, then connect the phone to your computer with the USB cable and hold down Volume Down and Power at same time for 10 seconds.
Please let me know if that didn't work, so we can continue troubleshooting.
It is a method to force reboot the phone. Call that phone and do you hear it ringing ?
I'm afraid it is the display that has failed.That is why nothing is showing up on the screen. Your may need to take it back to the store to replace the screen. I want you to remove the battery, wait 5-10 minutes (to reset the components inside it) and then put the battery back and turn it on. See this video to know how to remove the back cover to remove the battery --> https://www.youtube.com/watch?v=7rwrmdDZI14
Let me know the results please.
I'm very sorry. The display of your phone has failed. You will have to take it back to the store to replace the display. If it is less than 1 year old, they will replace it for free.
We've already tried all troubleshooting steps so far and this is something we can't fix online. I know this might not be the answer you want to hear, but there no other solution. If you are not satisfied, please don't rate me bad or poor. You don't have to rate anything if you are not satisfied even if the system asked for rating.
