i just got another no-solder chip. i was very reluctant since a no-solder fried 2 of my systems before. i installed it, made sure no ribbons were pinched or anything. first time it worked fine, played game for 5-6 minutes. 2 hours later i turned it back on and now the tray is opening and closing on it's own every 5 seconds. like the chip is stuck in switching mode just going open close repeatedly. weird huh? yet another reason i love my fliptop.
