          Toshiba Satellite C50-A won't power down
          by ju123
          Hi guys,

          So, I've been racking my brains on this one.

          I have a Satellite C50-A which I'm repairing for a friend.

          I recently replaced the main board due to failure.

          Following this, absolutely everything works perfectly, except for the fact it won't power down.

          Initially, shutting down via Windows would shut the OS down, screen would turn off (noticed the lighter black go to what looks like the darker black powered off screen as though the backlights have powered off), however the laptop was still running internally with a spinning...

          Problem with LG Plasma 60PM6700 - Random power downs
          by theone111
          I have an LG Plasma TV 60PM6700 for the past ~12 years.

          In the last ~3-4 months I have been having some issues.
          1. Problem: It started with random picture disappearing (sound still worked).
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait a few seconds before turning it on again.
          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
          3. Problem: TV shuts down

          Asus x512dk rev 2.1 power on problem
          by Duranitron
          When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

          Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...
