A600 – Monochrome signal on composite

Amiga 600 came in for repair and recap.

Beside the recap this the machine had a problem with the composite video signal, it was monochrome.
Problem: bandpass filter Z221 was broke.

That bandpass filter (and also delaylines) are not for sale anymore, so you got 2 options to replace this.

  1. Get one from a scrap board
  2. Get a replacement encoder pcb with other video encoder ic with internal bandpass filter/delaylines. See: http://www.amibay.com/showthread.php?98450

I have some scrap boards, so I took one from a scrap board.

Problem solved.
