    LG 29EA93 - No video

    Hello!,

    i've here a LG29EA93 monitor that no longer shows a video signal.
    The strange thing is that the menu is working without any problem. I can make settings, switch input source, reset to factory and so on. Fully functional except the input video signal. I've tested all sources - all with the same issue.
    When i connect it to a pc the monitor is correctly recognized (name, resolution), the monitor shows "No signal" and go to "energy saving mode". After shutdown it turns on immediately and shows "No signal" again. This is a endless loop "No Signal" -> "Energy saving" -> Turn On
    I've already cleared the NVRAM via service mode menu. The monitor also displays "EDID OK" for all input sources - So i think the EDID EEPROMs should be also fine.
    I've also tested all DC-DC converters on the board - All voltages are fine.
    The logic board has a TUSB3410 USB to UART chip that is directly connected to the video scaler (STDP9320). I tried to listen to it but got no data (Debug mode in the service menu was activated) Perhaps i do it wrong..

    Now I am rather at a loss.
    Maybe someone can help me? :-)

      Samsung monitor Installed 1 cap wrong, now menu button dead, "no signal detected" msg
      by glutton4punishment
      Samsung synchmaster 226BW.

      Before I replaced 5 caps, the screen was dim.
      Sometimes it wouldn't turn on.

      I opened it up, and found 4 bad caps in the pwr supply section.

      I unfortunately installee one backwards, i.e. wrong polarity.

      When I turned it on, I head a loud pop, and I quickly shut it off.

      The replaced caps are 3 860uF 25V's, and 1 330u 35V.
      One of the 860uF blew.

      I didn't have another 860uF at home, so I tried it with a 1000uF 35V cap (I remember the reading of the 1k uF cap was close...

      Philips 58PUS7805 Menu working but no/weird picture from video sources
      by Ierwin
      Hello everyone,

      I got a 58pus7805 that shows some weird behavior.
      The menu and remote work fine and the picture is looking crisp and flawless while navigating the menu.
      However, when a video source is displayed the screen either goes solid green (HDMI), solid black (SAT TV) or shows some fragments on mostly green background (AVI Playback from USB).

      I tried to reinstall the firmware through the menu which was rejected saying it already had the latest version.
      I managed to install the latest official firmware by holding the control button while plugging...
