U2715H, random restarts

Question

After about 3 years, my U2715H started to randomly restart. This occurs both with and without the PC hooked up (Win 7 64Bit, GTX 970 through HDMI) and with different power sources and cables (multi-outlet, single outlet, different power cables).

The restarts are not predictable (sometimes giving me 15 solid minutes without a restart) and then again one every few seconds) and I haven't been able to tie them to anything in particular. Since they also happen without a connection to a computer, it seems to be a pure monitor issue. The problem had first occured in December (when I still would have been within the service period) but disappeared again after a few days, so I forgot about it again.

I have factory reset the monitor and tried to run the Self-Test and BID but get an "Access Denied" page only.

Please let me know what else I could do.

Best,

Julian

I am not sure if the BID will 'show' an intermittent restart? U2715H BID =* Turn the computer off* Turn the monitor off* Disconnect the power cord from the monitor* Disconnect ALL other cables from the monitor* Press and hold in the monitor power button for 15 seconds* Reconnect ONLY the monitor power cord to the monitor* Turn the monitor on* At the same time, press and hold buttons #1 and #4. A gray screen will appear* Press Button 4. The color of the screen changes to red* Press Button 4. The color of the screen changes to green* Press Button 4. The color of the screen changes to blue* Press Button 4. The color of the screen changes to black* Press Button 4. The color of the screen changes to white* Press Button 4. The color of the screen changes to text* Press Button 4 to Exit the BID

Thank you, Chris.

I had a wrong idea of what the BID would do, so had more hope in it. But, as you suspected, it didn't really help. Yesterday evening I had a long session without any restarts and had thus hoped that it, once again, had resolved itself, but this morning it came back stronger than before. The weird thing: I haven't changed anything in setup or use.

It does sound like an intermittent failure of the monitor.

* To check the warranty status, go here and enter the Service Tag number in the blank
* Click Submit
* Click Warranty
* Look for the "Warranty expiration date"

Warranty has expired Dec 21, 2017. So, we're off by a few months or, as I stated in my first message, I was just still within warranty when the issue first occured but then decided to fix itself after two days. Since it didn't occur again, I forgot about the problems and let warranty run out…

Anything that could still be done?

No, not from a warranty perspective.
