Hey all,

Last couple days or so I have been experiencing an issue where my monitor (TV) has been turning itself off then back on without my interaction, I contacted the manufacturer and they helped me "restore factory" settings but it hasn't fixed my problem, just curious as to if anyone has experienced similar issues with their GPU being the culprit of the problem

my rig:
Windows 8.1
CPU: I7 3.4ghz
GPU: Gtx 1060 3Gb
RAM: 16Gb

Hello, do you use the TV as a TV as well? If so, does it do this while watching TV? It always restarts, turns off and right back on again? What brand and model? It's likely not the GPU...it could be the content of the signal, as in the brightness level, etc. triggering the reboot.

Some smart TVs have issues with restarting, with different causes, but all TV related. I can tell you more when I have a brand and model, unless it's an off brand (TV tech 30 years). Bear with me as I'm usually only on late evening pacific time.

If you see any pattern, let us know. It does it watching video, after TV is on a certain amount of time, etc.

Not generally, I do use it for my PS4 (rarely) I mainly use it for a PC monitor

TV - Sony Bravia (7ish years old) - KDL-40SL150

I was on "chat" support with Sony tech support where they gave me some steps to follow through with:
Unplug device from power source for 3-5 minutes and plug back into another power source
Factory reset device / Updating software to most current version

which I have done the listed above with maybe a delay before the turning off/on process happens

as for pattern recognition there it little to no tells as to what makes it happen when it does, although as long as I am doing user input it doesn't have issues which is the reason I thought it could be GPU related

I find it happens when I am streaming a movie (Netflix / VLC)

Ahhh, that's a 10 year old TV. That particular model didn't have any known restart issues (usually older TVs just shut off, didn't restart). If you have the backlights all the way up, you can try turning them down some and see if that helps. You can get into the diagnostics and see if any errors stored that will point me towards what is happening. Again, 10 year old TVs did not commonly restart, they just shut off. You could have a bad cold solder connection.

To get into the diagnostics screen. With TV off> Press quickly one after the other

Display> 5> Volume +> Power

The TV should turn on with the diagnostic screen, just power it off to get out of the screen

To be honest, no parts are available, so if it gets to the point you can't stand it, it's new TV time ;)

only part of the diagnostic menu that had any input was the 101-WDT (Watchdog timer) which was a 5, other then that they were all 0

WDT is indeed showing a restart, but Sony never meant for WDT to point towards a problem, it was only for diagnostics on the production line. Possibly the Main board since it's restarting, but again, other than possibly finding a used one on eBay, none available. I can find the part# if you want.

It seems very straight forward it's a TV issue at least ;) Not to spend your money, but the price of TVs and monitors as opposed to when that was bought is crazy low ;)

True enough, I have another TV/Monitor to use anyways!

so far since following your advice about factory reset, my issue has happened twice! so i call that a win/solution!

Thanks so much for your help!
