I see you were chatting with the site assistant. I am Mike, the field technician assigned to help you. If you see a pop up for phone call service, it was not sent by me and I am not available by phone. To get started, I need to know you can see this message and are able to reply to me here.

-If you disconnect the cable box audio/video cables from the back of the tv, does the tv still behave the same way?

Please try this:

-remove power cord from tv.

-remove audio/video cables from tv.

-wait 3 full minutes, then plug in ONLY the tv power cord.

-turn on the tv and observe if it will stay on or not.

If it still keeps rebooting then the tv needs diagnosis, parts, and service. Usually this symptom is a defective Main board. The whole back of the tv has to come off and the board replaced. I can help you with that or direct you to a local repair shop (provide your zip code).

the TV does come on and it says I have no cable connection
Expert:  Mike G. replied 9 months ago.

so the tv is not rebooting now?

-unplug the cable box power cord.

-plug the audio/video cables back into the tv.

-plug the cable box power cord in.

-observe as the cable box comes on.

If it starts rebooting again, it is the cable company equipment and they need to resolve it.
