flicker fixer issues

[Sutty100]

I bought a home made flicker fixer scan doubler off ebay and have a few issues which I wondered if anybody else has had? First workbench does not look great lines scanning across and the image "wobbles". In games the image is good but only takes up the top part of the screen leaving around a third of the bottom blank. This is with an amiga 1200, Over the weekend I am going to test it with an amiga 500 and a tv with VGA in. Should I try and get a refund or are flicker fixers generaly not perfect? Really dissapointed being as this cost £100 and I  was expecting great things!!

I did take a video of it on my phone but it is not the best quality and quite hard to tell the crap quality of the camera from the crap quality of the flicker fixer!

There are lines going diagonally across the screen they go one way for a  while then reverse direction. It defiantly isn't near perfect! He has agreed to do a return but I have still wasted £10 on p+p

I had a similar problem with mine, the sceen would freeze but the 5% of the top screen would work. I wast do to the converter nor supporting the PAL resolution. In your case it may not supprt your current video resolution.
Try to change the Amiga resolution to NTSC or PAL which ever you are not using and see if the problem goes away.
do you cave close up or model number of the ff?

I tried all available resolutions in workbench but to no avail. It doesn't have a model number or anything like that on it... should of been a sign! The link to it is below:

I would strongly advise avoiding it!

I was using a 500 PSU I do have a 1200 one so I will try that later to see if it helps although being as he advertised this for use with a 500 you would expect it to work!
