Hello,
I have a D9800 I would like to get working.
I power the monitor on without the PC hooked up and I get a "no signal in" displayed on the screen. Green light on the back of monitor is on, so the monitor is getting power.
When I boot up the PC I can't get an image before windows in BIOS, DOS, or after it enters Windows. I can see a very dark/wavy/stretched image of my Windows desktop once it enters Windows. If I hook up a standard PC monitor I can see an image within Windows just fine.
I have tried booting to safe mode, changing refresh rates, drivers, etc. Nothing will make it display on the WGD9800. This machine worked fine on this monitor in the past. I also hooked up a different machine and it has the same issue.
I am thinking it could be the LCD controller board? How can I test/confirm this? How can I determine what my issue is and fix it?
