- Please turn Off the cable box, does TV still show error message?

- - What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
These info will help to troubleshoot the problem.
Thank you.

OK, please make sure bluray power is Off as well and pull the fire stick form TV for a while to make sure the error message isn't coming from any connected device. Does the error message still flashing?

Sorry to hear that, it seems TV firmware/ internal software has been corrupted for some reason and keeps showing error message, tried to unplug TV power cord to get it reset but it didn't work and this kind of problem mostly occurs because of failing EEPROM chip that stores firmware data, I'm afraid you would need to replace main board of TV to resolve the problem. Please check with www.shopjimmy.com with TV model number to get price info of replacement main board if you have plan to do it yourself.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue.
I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.

do you think firestick could have done this? dont want to put it on another tv if it could be the problem.
Expert:  Shahid replied 1 month ago.

I don't think any video device connected to TV has made that problem in TV, it would be aging effect to electronic components inside TV so the EEPROM chip went bad without any warning, can say coincidence.

You can connect firestick or bluray to any other TV and both devices will work fine. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page.
