JA: What's the make and model of your tv, and can you guesstimate how old it is?
Customer: Sony. KdL-40z5100
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?

JA: How long has this been an issue? What happened right before this popped up?

JA: Anything else you want the TV expert to know before I connect you?

Ok thank you

Offhand, if the issue occurs with any HDMI input you select- that would point to a Mainboard issue with the TV (where all of these cables connect). However, first try a couple of reboots- which are both tests and attempts at a fix.

Unplug the TV's power cord and remove the HDMI cable from the cable box to TV. Disconnect the Amazon Fire and then plug it back in, but leave the cable box disconnected. Plug the TV power cord back in and turn the set on- does it shut off? If no, then repeat those steps and this time only plug the cable box in and see if the TV stays on.

Let me know how you make out as this gives me information on what's causing it.

Does the TV stay on with only the Fire connected?

Cable box

Hmm, okay. Please try a hard reset of the TV next. Basically the same steps, except after it's unplugged form power, remove both HDMI sources- then press and hold the power button on the TV itself (not the remote) for 12 full seconds then release.

Wait a minute, then reconnect both HDMI sources to the set- plug it back in, and turn it on and select one. Let me know what happens please.

Is the tv supposed to do anything after i hold the power. Button down for 12 seconds? Is the tv supposed to be off when i do the hard reset?

No it's not supposed to do anything, this drains current from within the TV. Also, the TV is supposed to be unplugged during this- so yes it would be off.

everything seems to be working just fine. If the problem persists then maybe look into a new tv?

Great, and I'm glad to hear that. This would point to a glitch, or a fault occurring with it's Mainboard. If the issues persists, you're generally looking at between $250-$275 to have the mainboard replaced, so in that case I would suggest looking for new, instead of repairing this set.
