[mythtv-users] Problems with VGA/RGBHV and Mitsubishi HDTV

[conkel at sunpower.com]

Hello, I've been browsing through the archives and can't seem to find 
anyone else that has had this problem. Here is my hardware setup related 
to my problem:


P4 1.7GHz
512MB RAM
Geforce 2 Video Card using VGA out
Mitsubishi WT46809 (connected with breakout cable)
Hauppauge PVR 250

I have gotten MythTV set up and running great. Recording works great with 
the PVR-250, I've got it running 1920x1080i and I'm working on getting 
Lirc running now.

My problem is that my TV doesn't want to wake up after I turn it off for 
an extended period of time. I leave the Myth frontend running and I turn 
the TV off when I'm done to prevent burn in. If I leave it off for more 
than a half hour when I come back to turn it on it comes on for about 5 
seconds and shuts itself off. 

I can get it working again by unplugging the VGA from the back of the 
computer, turning on the TV, and then rehooking the VGA cable back to the 
computer. What's odd is that I can turn the TV off and back on, just not 
for an extended period of time. 

Here's what I've tried to fix it:

Disabled screen blanking in BIOS
Set DPMS off in xorg.conf
Disabled screensaver settings in xorg.conf (ServerFlags)
"xset -dpms s off"
"setterm -powersave off"
"setterm -blank 0"
(I know, these are for console, but I'm trying everything here)

I'm at the end of my rope here, any ideas? I can post my xorg.conf if 
needed. Thanks in advance!
