Keyboard -short on ribbon cable killed MacBook

Airport no longer had reception, so opened MacBook to check antenna. When I pried off the ribbon cable for the top case, half of the pins pulled off the ribbon connector (in the white plastic housing). Micro welded them back on and reassembled. Did not boot, so took it apart again and discovered that the 2 first pins (bottom from the left) were shorted. Repaired the weld and put it back together. Worked ok, but keyboard was still intermittent. Progressively got worse. Mac would not boot up, becoming slow, etc. Now, completely dead. When powering it up, all I get is the DVD spinning (I left a boot disc inside) and the LED blinking rapidly. No startup tone, nothing. Checked the RAM, hit the thing, to no avail. Wondering if the short might have damaged the logic board. Regards, DJT.

Ok, so had the idea to check the RAM. Had pulled them out, and put them back in prior to the death of the MacBook, and thus to no avail. But, had not tried to take one out at a time. Did it today, and bingo, MacBook lives again (on dead RAM chip). Why and how? No idea. I guess I was right to wonder how a logic board (or any other type of digital electronics) could die in such a progressive manner. I was at 2 steps of throwing the thing in the garbage.
