Amiga External Flicker Fixer on Amiga 4000?

[SACC-guy]

Did you plug this adapter in while the computer was on??
The amiga 23 pin video is NOT hot plug device.
 
I have used several versions of this type of adapter, still work after all these years.
Maybe try again plug everything together with out power (if you're lucky)...
after a few moments warm up, it might come back up. The one I got from SoftHut took a couple of minutes to sync well.

I've just plugged it in now and turned machine on.  Both the lights on the flicker fixer are operational with the green (FF-Mode) light flickering.  The message on my LCD is "input not supported."  I will wait a few minutes and see how it goes.  

It usually works straight away with my 1200 even with this LCD.

Thank you for all your input and support so far Really much appreciated that we have such a nice community

Do you have a vga (not lcd) monitor to test it on?

[SACC-guy]

BTW, any vga monitor can be used... that's the 31mhz
and watch for the setting of screenmode. Just boot with no startup-sequence.

for sure This is the type of thing a local users group can really be helpful with.
I'm sure it can be tested there.

you are welcome to SACC if you are in the area!

When you suggest boot with no startup sequence are you just referring to booting to the usual startup purple screen with the floppy disk?

Thanks for inviting me along, I'm actually in Australia

Wait! can you see the load workbench screen with the f/f scan doubler attached?

Does this mean your 4000 has no hard drive?

BTW, it is possible you have a flicker fixer only and not a scan doubler (15 to 31)

[SACC-guy]

There were two types of rgb boxes..
The just flicker fixer and the flicker fixer with scan doubler.

The amiga rgb outputs a 15mhz which was what the amiga monitor uses.
later, we got vga (31mhz) and we needed scan doublers to get there.

there are lcd's which accept both levels, as well as some amiga monitors.
If this box is working with the 1200 (?) the box is ok

We might need to look at the 4000 at the problem???

I have attached a pic of the unit.  Is it a scandoubler also?

Yes it look like the pics at:
