I think this may have something to do with the TV Smart Share software. All my media comes from my HTPC computer through an HDMI cable. My HTPC use a HDHomeRun Prime and a HDHomeRun Dual Tuner that is on my network to provide all my cable and network programs. The HDHomeRun Prime shows up as 3 Smart Share devices but not the HDHomeRun Dual Tuner, maybe because it is behind a network switch. When I select one of the HDHomeRun Prime devices there is a pause of about 5 seconds then the TV turns off and on. I thinking that the TV software update is having a problem with one or both of this Smart Share Devices. My original 4.02.62 firmware also displays the three HDHomeRun Prime devices and when I click one of them, it also pauses for about 5 seconds then turns off and on. However, as I mentioned already the original 4.02.62 firmware doesn’t turn off and on during normal operations.
I also notice that when I first turn the TV on in the morning that after about an 1 hour and 10-20 minutes it always powers off and on.
To test my theory I have removed the network dongle which prevents the TV Smart Share devices from being detected and should prevent the problem. I'll post back my results.
Since I removed the network dongle 1 1/2 days ago there has been no problems with the TV turning off and on. I notice the HDHomeRun firmware had an update so I installed it to see if that may help. I plugged in the network dongle to see if that may fix this. Right after I turned the TV back on, it run for 15 minutes before turning off and on again and is back to turning off and on every 1 to 3 hours now. I differently think the TV is having a problem with one of the HDHomeRun devices.
I've also noticed that the TV model/type is GLOBAL-PLAT3 and serial number is SKJY1107. I read that the service tech should have gone into the service menu and set it back to the correct numbers. Anyone know the key code commands to activate the service menu?
The service tech came out and he changed the TV model and serial number. He talked by phone to his support person and after testing for several other possible reasons for this problem, they have asked me to remove the network dongle and use a direct network connection to see if that has any affect. They said if that doesn’t fix the issue then I should remove the HDHomeRun devices from my network or run the TV without the network. I was hoping that the support person would at least suggest that maybe the 4.03.02 firmware update was at fault (since the original 4.02.62 firmware worked fine) and that they would look into this issue, but of cause, I was being too optimistic.
So, that’s it. I’m on my own. I will update this post if the direct network connection does fix this issue. Otherwise, I’ll have to go back to the original 4.02.62 firmware or use the TV without a network, or maybe take it back to Costco.
