Can't get any display with OS 3.9

Please describe how the 1084 is connected to your Amiga.  What port on your Amiga is the cable plugged into?

Yes 1084 is fully PAL and NTSC capable.

Here are my theories:
1. Connected together wrong.
2. P96 or CGX is installed and forcing the workbench onto some impossible frequency.
3. Your monitor or tv is from Europe and you are in USA so you are using the wrong powersupply.

Since you can see the early startup screen that actually rules out 1 and 3.

So it must be #2.

What is P96 or CGX?  Anything I can do to remove/modify?

P96 and CGX are hack patches that modify AmigaOS into being able to use a pc gfx card.  If it is installed and your workbench is trying to load up onto a gfx card screen then you will not get a picture on your RGB port.

The easy way to remove it is to just delete the appropriate monitor driver out devs:monitors/

But copy them to another safe place first before deleting in case u want them back someday.

Do you have any monitor drivers that contain the words Virge, Voodoo or anything pc or windozey sounding?  .... hmmm u should post us a list of all your monitor drivers so we can see if anything suspicious is lurking about in there.

Can you copy your S:Startup-Sequence and S:User-startup to your internet computer and post them here?

There has to be some sort of hack installed that is breaking your workbench.

There is an evil hack in your user-startup that is fraxx0rizing your sweet innocent workbench.  I would really like to know which hack caused your problem so we will know what to tell the next victim who comes along.

Here is my next guess:  (and it isn't even an evil hack
You have ModePro or some similar hack in your user-startup and it was set to promote your workbench to some impossible thing.

Or maybe it was Planes2Fast.  That will make all workbench gfx disappear.

I wish u would show us ur user-startup
