scandoubler / flickerfixer problems

The only thing I didn't like in those was the way you got the VGA connector out of an A1200 case, you basically had to leave the case open.

Easy enough to remove the unneeded RF adapter and put the VGA connector there.  That is what I plan to do.

Good idea! I was thinking about making a custom plate for the little expansion port on the rear right side (already have a PrtJunior) but that's better.

I own 3 flicker fixers at home and used a 4th one at the store.

I never had any problems with them. 1988-2003

I found something that looks exactly like the one I have.

MV1200 scandoubler/flicker fixer

I use it in the A1240 in a Tower with a big PSU powering it.

The MV1200 should be plugged in and the Amiga switched on for at least 5 minutes before attempting this procedure to ensure that the MV1200 has reached operating temperature. Try to have as many vertical lines on the screen as possible, or load a picture which contains many alternate black and white lines. Use a small screwdriver to move the potentiometer labelled Adjust. Please note this is a high performance multi-turn multi-precision potentiometer which can be turned about 20 times from end to end.

ChaosLord, what models ff/sd do you have? they internal for 1200s?

This is how analogue flickerfixers work.

Analogue circuits always drift due to temperature changes, so just let it warm up and then adjust the picture with a good set of flickerfixer test patterns.

Digital scandoublers/flickerfixers don't exhibit this problem, but you can't connect one externally - it needs signals from the chips.

I guess I should tune my A2000's flifi again, it's gone terribly out of sync.. Then again, I normally only use it for the early startup menu..

1988: The Original Microway FlickerFixer installed in video slot of A2000.

1990: The builtin flickerfixer of the A3000 (x2)

2000: I bought an A1200T and it came with an internal flickerfixer.  I have no idea what kind it is.
But it is beautiful.  :-)
