    Dell 2007WFP on and off with powper + 2 inputs LED on

    Ok.. guys.. this is a weird issue, that I have yet come across.. chance is the mainboard is the problem, but figure I ask another person's opinion first..

    I have a 2007WFP which when I turn it on, it show the computer desktop along with a blue PIP (see picture) from RCA for about 2 second then it goes black. But instead of it shutting down, the bezel led shows input from 2 sources and the power led remain on (see picture). If I turn it off and then on, it cycle through the same thing..

    I try to click on menu or other buttons, but no respond, and if I don't plug in vga it say no input.. and all button only shows "no input"

    I taken it apart and took picture of all the boards. All cap seems ok.. fuse is working. didn't go them or ccfl to test the actual backlight, but it seems to be something else.

    What other thinks?

      Philips 58PUS7805/12 showed no picture; after T-Con replacement, shows halo
      by Rauni
      Hello, this is my first post on this forum, and my first attempted to repair a TV.

      My Philips 58PUS7805/12 stopped working recently. It is not that old, about 5 years. We were on a trip for a few days and when we came back, it had stopped working out of a blue (Perhaps our house was hit by a lightning strike? Don't know.)

      Read from a guide that I should test if the screen shows picture with one of the T-Con cables disconnected. Did that, it showed perfect picture (first on left, later on right side).

      Read also that we should test what happens if we...

      Dell XPS 9300 (LA-H811P) internal display only shows Dell logo then nothing (everything else works)
      by TheQuentincc
      Hi,
      I have a Dell XPS 9300 that's working perfectly fine with an external display plugged, from windows the internal display isn't detected. At boot I can see the Dell logo then when it should display the boot/bios or whatever the screen goes black (no backlight, no image using a flashlight). I tried unplugging everything on the motherboard except the eDP cable but it didn't helped (so it's not the lid sensor). LCDVDD/backlight power are powered down when this happen, PANEL_BKEN_EC and ENVDD_PCH are also down to 0v. It's weird, it almost feels like the motherboard is shutting down the display...

      Dell Inspiron 15 3520 - AC Adapter shows "Not Installed - Not Charging
      by Stanley1843
      Hello,
      I bought a used Dell Inspiron 15 3520 laptop and the battery isn't charging. When I go to the BIOS setting it shows that the battery health is "excellent" but on the AC Adapter shows "not installed". I checked the pins from the power connector on the motherboard and I didn't found a short on the PS_ID pin. It dould be the charger (I don't know if this is the original) or what I have to check?...

      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
      by Bowline
      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
      I have tried multiple different Dell power adapters. My Dell...

      Samsung Odyssey G9 (c49g95tssr) no picture or backlight. Power LED shows
      by grimreaper420
      hey guys,

      i bought 2 samsung odyssey g9's for a decent price. they both have the exact same fault. when plugged into a power source, the blue led powerlight shows, but when turned on there is no picture, no backlight, no menu, nothing. when plugged into a laptop the laptop recognises the monitor, but keeps disconnecting and reconnecting.

      dont have any schematics or diagrams unfortunately. any ideas?

      thanks
