    Dell 2709WB 2709W Monitor not powering on.

    Hi guys.

    I was advised to ask here about my problem.

    I have a Dell 2709w or 2709WB (same monitor, different regions).

    I was switching input from my laptop to desktop and it would not display an image after that.

    The blue power LED is on when the monitor is plugged in, but none of the buttons register (I can't turn it off using the on/off button on the front).

    There is no picture on any input, just black screen, no OSD.

    I have opened the monitor and had a look at the power supply. I dont see any odd looking capacitors (puffy?). I can post a photo of the guts if need be.

    While I think I'm pretty knowledgeable with computers, this sort of stuff is out of my league.

    Any help would be much appreciated.

    Cheers

      ironmanonsteam Did you solved the issue? I have the exact symptoms. Right now I've installed a fan, to cool it down - no success

        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...

        Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
        by DanPoka
        I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
        Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
        This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

        HannStar Hanns-G HC194d LCD monitor repair
        by momaka
        Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

        Issues Reviving Old Dell 2408WFPb Monitor
        by Jesus Coder
        Hello everyone,

        I have been having some difficulties reviving an old Dell 2408WFPb PC monitor that I received for free. When I first acquired it, the backlights of the display were on but alas no image was showing. After extensive research on the topic, I went ahead and purchased a new t-con board for the monitor. After installing the board, I was then presented with a new screen that was half black and half green (more so black). I have been unable to figure out what to do next as I have limited knowledge of display electronics. Might anyone on this forum have an idea of what may...

        Dell 34 inch U3419W Monitor with thin stripes on partial screen
        by ChristianBr01
        Hello everyone,
        I have a Dell U3419W Monitor that has some thin stripes on a part of the screen since Tuesday.
        This lines cover about a third of the screen and appear for 2 seconds before disappear for another 2 seconds.
        This repeats the whole time. I have not opened the case yet cause I had no time, but will try to fix it on this weekend. For me, it looks like a problem on the TCon... Am I right?
        Does someone have seen this before?...
