Hi
when I have MY TV on full screen, if the televsion is turned off, when turned back on the TV is in a window, with no picture or sound, I have to press back, to main menu then select my TV to get picture and sound.
Also when this done the remote volume and mute have no effect on the televisoon volume, niether does the mute function work (although the on screen display says mute)
I assume this is an HDMI issue, don't get this with windows media centre however.
logs attached
can anyone suggest a way out of this?
regards
rob carter

HDMI connection gets closed when TV changes the input. You could try EDID override, or some driver setting to solve the issue. Do you hear "windows' hardware unplugged" sound when changing the input in tv?

Hi

No sounds, or messages in the event logs, media portal does the same thing if I am viewing a picture; turn off the TV when it's turned back on media portal has exited to the picture browser, I can understand why this happens from the log entry.
Windows media center doesn't do this, it remembers the last view. Media player (windows and media player classic) don't do it either.
Is there some way of disabling this 'feature'?
thanks
rob

I had a problem like this with my Samsung TV.
Solved it by changing HDMI input to HDMI port #2 instead of #1.

I too have had this issue for as long as I can remember with my Sharp flat-screen.

The only true-fire way to bring the display back is by starting a video or tv (as pointed out by the original poster)

I have turned off every screen blanking option I can find in the config, but it still turns the display off when idle for a few minutes.

I tried changing the hdmi input on my panasonic, the problem with TV changing back to preview goes away, but the audio volume function still becomes inactive.
On my panasonic TV the second HDMI does not support digital audio (although sound is OK), however when the tV is turned back on the full screen tV is still active but the osd volume has no effect whatsoever (including mute)
Can some one confirm if this is a bug in MP?
thanks
