I have just installed a Magic 3.1 plus Modchip into my V7 PS2. To test it after words I used a backed up movie (Verbatim DVD+R Data Plus) which had a perfect picture before upgrade and this played fine using the boot sequence, however the picture was jerky and quality has deteriorated from what it was. (I have no shorts between pins/pads as I have checked with a Multimeter) I tried one backed up PS2 game which also played but again picture quality is not what it was. And lastly I tried an original PS2 game and again it played but same issue with picture quality. 1: Is this something to do with Modchip or is it something to do with a cable that I removed to get at the underside of the board or laser section.
