    LG 42LB1DR DVR TV Powers Up For Sec Two Then Shuts Off

    I have an LG TV with built-in DVR..

    It powers up fine, but after a few seconds, it shuts off..

    I have tried it without the DVR HD attached, no luck..

    I have replaced the Power PCB and both Main Boards with no luck..

    Thinking it might be the inverter boards, I tried it without the inverters hooked to the Power PCB...

    Same thing. Powers up for a sec or two and then shuts down..

    I am at a loss on how to proceed..

      Help with Dell Latitude E5470 that shuts down when moved at all. Powers up, but no charge, power jack has brown burn marks
      by lowpost99@gmail.com
      I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but...

      Dell laptop powers up with kb backlight about 10 seconds, then shuts off
      by survivalbloke
      I've got a Dell Latitude 5580 which came in for no power. It's not exactly a no power issue though. The battery was puffy so I replaced that, but the symptom is that when the power button is depressed, the keyboard backlights will come on for about 10 seconds then go back off. Before depressing power button, I am drawing 112ma and oddly, there is no change in current draw once the button is pressed and the keyboard backlights illuminate.

      Any ideas?

      DELL LATITUDE 5420, ST 20TFKN3, LA-K491P REV:2.0 (A01) powers on and die about 15 secs later, no video
      by Chivo77
      hello friends, I have a DELL LATITUDE 5420---MODEL P137G, ST 20TFKN3 LA-K491P REV:2.0 (A01) and its quite a challenge. It powers on with the battery disconnected, lasts on for about 15 secs, and then shuts off. It does the same with battery only (no adapter). With battery and adapter it sometimes starts after hitting the button several times. It displays nothing in every case. Since only the Boardview is available, I guided myself with schematics similar to this laptop (I'll add them down).Some measurements:

      1- After receiving power SIO_SLP_S0# goes high and never changes.
