- Windows 7 Media Center on an
- Acer Revo with
- nVidia ION graphics, hooked to a
- Panasonic 720p TVr via a
- Pioneer VSX-819 A/V amplifier, using
- HDMI for video and audio.
I leave the PC running 24x7. I turn off the TV when not watching it.
Sometimes, after the TV is off overnight and the PC is idle, when I turn the TV on, Media Center shows a black screen, even after a mouse wiggle or keystrokes. Additional symptoms:
- I do get a mouse pointer when I move the mouse.
- I do not hear sound effects when I move the mouse (that I would normally hear when mousing over a Media Center button).
- The screen (back-light) gets slightly darker when I move the mouse to the edges of the screen.
Here are some things I’m trying:
- mouse wiggle - gets a mouse pointer, and back-light level changes as I near screen edge, but screen always blank.
- press space/shift/letter key on keyboar - no effect
- press the dedicated start-IE button (a globe) on the remote:
- Starts Internet Explorer
- Shows a media-center-not-responding dialog
- Media center works after I select Restart.
- Disabled screen saver and disabled monitor-off power-save.
- amplifier off and back on - no effect
- Configure PC and TV to send video via VGA (as a preventative, not as curative) - test in progress
- run hdmiOn.exe from a telnet session
- tv off and back on - ???? (not tested yet)
- "devcon reset" followed by the device ID - not tested
- Might need to "devcon status * > C:\temp\foo.txt" first, to learn the device ID
- Could it be running on another virtual monitor? Disable non-HDMI output. Is there a move-to-next-monitor hot-key?
- alt-F4 (it does work when NOT black first)
- Enable monitor-off-on-idle. Then maybe a mouse wiggle will turn it ON.
- unplug and re-plug monitor. if this works get an HDMI switch. What if I switch monitor on the AMP?
- Does it happen if I go direct from PC to TV via HDMI?
- make it go to sleep on idle. When wakes up, does THAT make monitor light up?
- Remove Nvidia driver and use Windows driver. Re-add Nvidia driver.
- Can I set up a hot-key (maybe via Autohotkey). To re-set video (maybe change resolution and back). Maybe a monitor-off followed by a monitor-on.
- Set up a background task that periodically writes current monitor settings to a log file. See if/when something changes.
- Can test monitor on/off via telnet?
