Posted by: clandestino on 2014-10-27 16:47:30 Finally I changed that chip and the screen issue gets solved! But my joy didn't last too much. After some reboots, system won't start up any longer. I get the blinking question mark... I checked hard disc cable but it's well plugged. What could be happened?
Posted by: techknight on 2014-10-27 16:55:38 hard drive took a shit. Common problem, especially if its a quantum.
Posted by: Scott Baret on 2014-10-27 19:15:35 That video board is seriously the only thing that causes that to happen?? Guess I'd better hold on to that analog board I wrote off two years ago and try it with a different video board; I definitely have three or four extra video boards just sitting around from dead analog boards!!!

Posted by: uniserver on 2014-10-31 07:48:19 In this case with my order of 10. I emailed orders@mouser.com Told them to add 10 to my 1st class order that i had placed the day before. Because i knew it hadn't left yet anyway. They said no they could not add it. But would send me these out first class on them. so i paid my 3 and change and got here the same time as the other order.
Posted by: pep_one on 2019-09-01 06:07:24 Hi, I've a similar problem with a Macintosh Classic II. I've replace the 2N3904 transistor on video board, without positive end. Do you know what is the UE8 equivalent on Classic II? I would try to reflux the solder point. Thanks.
