1 Why is my device constantly power cycling?
Hello all,
I have a Vizio E500i-B1 50-inch TV that is about 4.5 years old. It currently power cycles every few seconds. I will see the Vizio logo and then a few seconds later it will reboot again. I’ve pulled the power plug and held down the power button for 1 minute, and that didn’t seem to help. I thought it might have something to do with the Fire stick I was using, but I plugged in a different Fire stick and it’s still doing the same thing. It just started last night. I’m obviously out of the Vizio warranty period. Can you guys give me any ideas about what I could possibly replace and if it’s something that I could even do? I’m just trying to justify whether it makes sense to replace a part or just replace the whole TV?
Thanks.
Blair

@oldturkey03 - thank you for the response. Here’s some additional information:
* I had the TV completely unplugged from the wall and turned it back on after about 10 hours of being completely unplugged with no peripherals plugged into it including the power cord. When I plugged the TV back in with nothing plugged into it tonight the power cycle DID NOT happen right away.
* I then tried to plugin a DVD player and it worked fine. No power cycles.
* The issue seems to be the Fire stick because whenever I plug that into the Vizio it instantly starts power cycling. I’ve tried 2 different fire sticks and they both cause it to get into this endless loop of power cycles. These power sticks both work perfectly fine on other TV’s in my house.
* The fire stick was working perfectly fine on this TV until last night when this behavior started randomly happening.
Any additional assistance would be greatly appreciated. Thanks so much!

Hi @blairr219 ,
Presumably the TV didn't do a firmware update just before the problem started happening?
If you're powering the Firestick from the TV's USB port try powering it with an external power source and check if the problem is resolved.
Did you try a different power cord to the Firestick?
If it works OK this way and there were no updates and you tried a different USB power cord to the Firestick etc, there may be a problem with the TV power supply to the USB ports etc.
Check the voltage output on the USB port to see.
Just some thoughts.

@blairr219 sound slike your TV is not the issue here but the Firestick. There are multiple complaints that are similar to yours and all seem to originate from that. See what happens when you follow the advice from @jayeff

@oldturkey03 & @jayeff thanks for the responses.
I'm using an external power supply for the Firestick already. The firmware version for the Vizio TV is 2.1.18.0000 but it hasn't updated recently.
I've tried 2 separate firesticks, both using external power and both of them cause this same behavior on this TV but work fine on other TV's in the house.

@blairr219 just to further clarify. Your TV works as it should. This only happens when you are using your Firestick?
