        Hi all, this will be my first attempt at repairing an LCD monitor. I haven't done much repair work in a long time, so I'm dusting off my gear and hoping for the best... Monitor is a Dell E196FPf no backlight. Image is visible on the monitor with a flashlight so I suspect just the inverter, or maybe a bad lamp, though none of the 4 come on at all, even at power up... 2 caps in the inverter section are bulged and have relatively high ESR (2 ohms) other than that no obvious visible signs.
        I have a similar situation to smason in the OP quoted above. I have 3 E196FPf monitors and all show the same symptom - the power indicator shows green and stays green - no blinking and no amber. After a quick web search that turned up this thread, I decided to disassemble one - sure enough, it has 2 bulging caps in the inverter section shown in smason's close-up pics.

        We've done a bit of minor cap repair to some older model car dashboards, but nothing really like a computer board. Before I dive in, any pointers - things to do, not do, watch out for, buy, etc.?

        Thanks in advance for any help.

          Re: Dell E196FPf

          I'm caught up on other projects and have replacement caps for these monitor boards in hand. Any advice on how to proceed? As I mentioned above, we have some soldering/cap replacement experience, but it was only on car dashboards about 10-15 years old. We've never tackled anything complicated like a computer motherboard. We do have a couple of different soldering irons but, for the most part, we're starting from scratch in both supplies and experience.

          Thanks in advance for any advice - or pointers to instructions we could use.

            I just ran across something that reminded me that I hadn't checked this in a while. Before we start the repair process, what should we know?

              Ok there is awhole forum devoted to this amongst other things
              Read this https://www.badcaps.net/forum/showthread.php?t=31448
              There is some useful ideas and a youtube video which leads to a whole series of videos on
              soldering.
              My tip - 40 watt iron Leaded solder with flux. more flux. if you are working in a cold place pre heat the board gently with a hair dryer or very very gently with a hot air gun

                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...

                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?...

                HP adapter for Dell monitor
                by paparazzo79
                Hi guys.
                I got myself used Dell 27" touch monitor but I got scammed again, seller sent HP adapter.
                Though voltages are the same, I suppose power supply design is not the same.
                So may I use it without any harm to the monitor?...
