Tech1, Read through a previous question that was resolved and you could have been talking to me. Same exact issue, different model.
TV remote- only power button works.
TV set- only power button works.

Hello, my name is XXXXX XXXXX expert is offline, I'll be happy to assist you.
Please allow me to ask you a few questions to diagnose the problem.

- How old is the TV and how long it have had this problem?
- Does power indicator light blinks on TV front?

Thanks.
Customer: replied 3 years ago.
Just over a year old. Problem started last night. Before factory reset the red led blinked 8 times.
Thanks Matt for the reply.

- Does power light still blink 8 times? if you are not sure, please check as this info will help to diagnose the problem.

Customer: replied 3 years ago.
No sir, solid red.
OK, does screen show faint glow when TV turns On?
Do you get any display or menu screen show up if press Home button?
- have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug and check?

Thanks.
Customer: replied 3 years ago.
No faint glow, I see snow. I unplugged all devices. All buttons will not work except power on remote and tv. Unplugged all day today. Still doing it now.
So screen has snow that means backlight is working.

How long TV stays On/ Power up and does it ever go to shut off itself?

Thanks.
Customer: replied 3 years ago.
Before factory reset it would shut off and back on every 15-20 sec. After reset it stays on but snow only and only power buttons work.
Thank you Matt for these info that helped to diagnose the problem.
Last question, is TV connected to internet? (through wire or wireless)


Customer: replied 3 years ago.
Yes, wired.
OK, can you please unplug wire from LAN port of TV as test, turn it On and check?
TV could get stuck to establish internet connection that is why we get other buttons non functional.
Please post back how it worked.
Thanks.
Customer: replied 3 years ago.
That seems to have done it, hopefully for good. Thanks.
Excellent Matt, now please reset TV one more time to factory settings, replug Ethernet wire back in TV and perform network settings to establish internet connection and check.

I trust my input will help you out. Please feel free to respond if you have any additional questions.
A positive rating to answer would be greatly appreciated!

Shahid.
