Macintosh Classic II Vertical Lines after clean & recap
Posted by: bigandy2 on 2024-07-27 22:50:08 Hi Guys, Have been battling away with an old Macintosh Classic II for a few weeks now. When I got it, it was completely dead. After cleaning and recapping both boards I now have decent voltages from the port at the back, fan and HDD spin up and I get vertical lines on the screen. Voltage seems to take about 10 mins from power on before it gets to a decent level +4.88 & +11.9 -11.8 and the screen comes on and disk spins up. Any advice where to go next? Cheers Andy

Cheers Andy I had issues around memory chips and sound chips. Also, check around egret chip. Might have to do some cleaning, or remove chips with hot air to clean pads / legs from corrosion. Recapping only part of restoration. If your unit works after recap and nothing else your lucky😉
