and does not power on .I have checked the fuse,capacitors,resistors,mosfet and
diodes and they have all tested ok.I have plugged the board into the AC outlet
and there is DC at various points of the power supply.I am also searching for a
service manual. -
Re: Dell monitor E153FPF no power
Mount the board back in place, DC Volt meter Black lead on the chassis, the use red probe to measure each pin of that white connector with Black wires and one red wire, tell us what the Voltages are.
I also need the straight shot picture of the board, and pictures showing how all the board are connected together since there are more than one version of this model.
BTW, beeping really does not mean much, the resistance reading is more important.Last edited by budm; 11-03-2017, 09:42 PM.Never stop learning

by BowlineMy 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... -
by DanPokaI 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...-

by Jesus CoderHello 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...-

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?...-

by paparazzo79Hi 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?...-
