    ACER AL2216W odd "signal" issue

    I got a widescreen Acer (AL2216W) in today, strange behavior. When you first boot, all works fine. Upon a reboot, the screen will go dark & will not come back on unless you cycle the power button.

    The monitor has AC power all the time, it's just that during reboot when it loses a signal from the pc that it exhibits this behavior.

    Other than that, no flickers, blinks, flaws, etc. No caps defective visually, no other visual defects that I can see. Any ideas where to start?

          Check the voltage regulators on the video board they can play up

              Acer Helios 500 (PH517-51) - unexpected reboots when laptop is warm (cold solder joint issue?)
              by Mirenia
              Hi everyone,

              got an Acer Helios 500 Laptop (PH517-51) for diagnosing with a strange issue:

              The laptop runs for a while (1-2 hours, sometimes less) and then suddenly shuts completely off, like someone pulled the power cord and restarts immediately after on its own.
              If this happened once, then the laptop only runs for a few minutes until restart.
              This happens regardless while staying in windows or uefi or in a linux environment.

              At first I thought of a normal overheating issue, but as I monitored temps with HWInfo64, nothing seems very hot.
              ...
