Thanks to all you guys in advance for helping me to solve my problem.
I recently bought a mac SE with the tipical scanlines video problem. Here an image of what I’m talking about
As you can see in the image the mac starts to the desktop, the start bong can be heard, but the image displayed has this scanlines patern.
I’ve followed all the Larry Pinas steps recomended in his Dead Mac Scrolls book, changed resistors 20 and 21, tried to tune up the cut-off resistor, but nothing has changed. Furthmore, I’ve swaped a known good working analog and video crt boards with the same result, which make me think that the fault is in the logic board, but I’ve not been able to find any clue regarding this video problem in relation with the logic board.
Any help would be greatly appreciate.
