    LG E400 totally dead

    I have the phone mentioned in the title.
    Does not boot, doesn't do anything, does not react to anything.
    I press the on switch, nothing. I plug in the usb charger, nothing.
    Battery is charged.
    The on-off switch works fine.
    Visibly, no part looks burnt.
    Any hint is welcome (or service manual of E400 or similar model).

      Hello, i bought dead nintendo switch oled.

      Shelly plus 1 dead, does not switch
      by CapLeaker
      Anyone got any Shelly remote devices around here?
      I’ve got a few of these and they were all working fine for about a year. Today I noticed that one of them that controls a single light switch isn’t working at all. I mean it’s so dead, even the light switch doesn’t control the relay. No clicking, no anything whatsoever. Unfortunately it’s in the basement in a dark room and trying to get it out is going to be interesting. Maybe there is some carnage in there, who knows. It was hooked up to power mains.

      The other exact same one is in the same room,...

      Micro Momentary Push Switch?
      by Natob82
      Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

      NEC TurboExpress On/Off Power Switch Replacement Help
      by grimacelord
      Hello,

      I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

      I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

      I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....
