Macintosh Classic II stars stripes screen error

[psypher39]

i recently got a macintosh classic II (at the MIT swap meet, that was "working") when i got home i tried to turn it on i heard the fan start up but the screen was blank. just blank nothing was happening, so i decided to open the beast up and discovered that all the cables to the board so i re-hooked everything (the power, the hard drive, and the floppy). after that i was feeling really good and turned it on only to see very thick vertical lines with dashes (i have heard this called the stars and stripes). after trolling the internet for answers i found out that the ram may be loose or need the pins cleaned i also heard alot about leaking capacitors. so i opend it up again and this time i took the ram out and cleand it with rubbing alcohol. i also looked at the board it didnt appear that any capacitors had leaked but i decided to clean around them as well. then i put the whole thing back togeather and ... same problem any ideas or should i just junk the whole thing??
