Nexus 5X won't turn on

Hi All,

I have an issue with my Nexus 5X showing no signs of life. A few days ago I noticed when I woke up that the phone had restarted randomly in the middle of the night as it was on the "enter your PIN to start Android" screen. Not a big deal - but never had this happen before. The phone was charged in and battery at 100%. Good thing I didn't have any alarms set!

Then yesterday, while plugged in and charged about 80%, the phone completely froze. I've had this phone freeze before, but only while running an intense application or something with high load, never while just sitting idle. I waited about 30 seconds just to see if it would recover, and then held down power to restart it. Then, when it restarted, it seemed to get stuck on a boot loop where it kept showing the Google splash screen, then going black for a second and then repeat. It did this about 5 or so times, until I unplugged the power cord, and it booted after this (not sure if the unplug had anything to do with it).

After it started, I was thinking how odd that was and that I hope it's not messed. I plugged it back in so it could finish charging. I checked back about 5 minutes later, to find it completely frozen again just on the home screen. I unplugged the power so I could sit down with it (why does it come with such a short cord? :p), and when I did that the screen went black. That was the last time it ever worked.

Since then I've tried everything from the usual steps including:
-leaving it alone for a few hours, not connected to anything
-plugging it into the wall charger and waiting
-plugging it into a computer and waiting
-every combination of holding just power, and holding power and volume down in the above combinations
-removing the back cover and disconnecting the battery for a few minutes, then reconnecting

The only sign of anything I got was, after disconnecting and reconnecting the battery, when I plugged it into the computer, and pressed and held power, the red led blinked about once every 10-15 seconds so long as I held power. Then I plugged it into the wall, and the red led blinked about 1 time per second for 5 seconds, and then that was it. Never any battery icon or anything on the screen.

I contacted Google, who put me on the line with LG. I was told the phone needs to go into a servicing, and because it is a year and one week old, I would need to pay them for the repairs. Of course I don't want to do this, especially considering I've owned multiple LG phones (including the completely terrible Nexus 4 - an experience so bad it made me not buy the 5, and almost not buy the 5X) over the years and spend lots of money on Google products (mainly G Suite for work). Although I believe the warranty issue is fully with LG, as they make the phone?

Does anyone have any ideas as to what might be wrong? Since it always seems to be charging related could it be a battery issue? Would a broken battery prevent the phone from turning on even if plugged in? I would like to point out this phone doesn't and has never had any other damage, and physically appears to be in excellent condition.

Thanks!
