Message: <blockquote data-quote="Brandt" data-source="post: 56518">My pismo began acting up about 6 months ago when I got back from vacation, plugged it in and it wouldn't boot. I finally took out the power cord and tried again and it booted. I hadn't had any problems since, until last weekend.Again, it wouldn't boot, with or without the battery in. I figured it was the bad solder problem in the AC card, so I dismantled it down to the card and found that it looked intact with no play in the AC connection.  All cards had been removed at this point.I reassembled it and tried again. Nothing.I ejected and reinserted the battery so that I could see the flashing single LED, then tried again, and it booted. I removed the battery and it kept running.However, there is no picture. LCD is completely black.I powered down using the power button and moved the laptop and yoyo adapter to where I have a CRT display. I hooked it up and plugged the AC adapter in.Nothing happened when I pressed the power button. I ejected and reseated teh battery and tried again. Now it booted, but there still is no picture. There is also no sound.I also plugged in my speakers. No sound. I turned them all the way off, took them off mute and pressed the mute button on the KB. Nothing.I power cycled. Still no sound. I pressed the mute button on the kb again. No sound.I ejected the battery to test the AC stream status. The laptop died.I tried again. Now it won't fire at all. I've tried to boot with and without the battery inserted.  The battery test button fires the LED, but the computer won't boot.Based on these issues, I'm wondering if it is still the AC Card, the PMU or the CPU card. Any ideas?Thanks!</blockquote>
