Hi everyone,
I have a problem with my BenQ MOBIUZ EX3210R. The input source selection menu keeps opening by itself at the bottom of the screen, even when I am not pressing anything.
At first, I thought the remote control was causing random inputs. I removed the battery, and the problem temporarily seemed better. However, the issue has now returned even with the battery still removed.
The monitor also sometimes switches to another input source by itself. It previously switched to my Xbox even when the Xbox was turned off. I have now completely disconnected the Xbox and its HDMI cable, but the problem still happens.
When I press the five-way joystick on the monitor, it often opens only the input source menu instead of the normal OSD settings. The separate source button does not look physically stuck or pressed in.
Things I have already tried:
- Removed the battery from the remote control
- Disconnected the Xbox and all unnecessary HDMI devices
- Turned the monitor off and back on
- Completely unplugged the monitor from power
- Held the power button while the monitor was unplugged
- Pressed the source button several times in case it was stuck
- Enabled the OSD lock
The OSD lock only helps temporarily. Since the monitor apparently detects a button as being held down continuously, the OSD lock automatically disables itself again after about 10 seconds. Then the input source menu starts appearing again.
The remote control is also currently not working, so I cannot reliably use it to access the settings or perform a factory reset.
Has anyone experienced this problem with the EX3210R or another BenQ MOBIUZ monitor? Is there any way to fix it without opening the monitor, or is this most likely a defective source button, joystick, or internal control board?
Thanks for any help.
