Hi All, I tried changing the chip that you mentioned earlier in the forum, the 8 pin one. And..................... It did not fix those pesky gray lines! I got the chip off my working 770 and swoped them over. Both worked just as they did before. I spoke to a friend of mine adn he suggested that there will be a corupt eprom somewhare, probably corupted by static or an incorrect cap somewhare. I have had enough of the broken one now so am selling it, If anyone has any ideas let me know and i will try it! Good luck. Nate.
