      That makes it easy to troubleshoot. Some parts of the circuit are common to both sides. The BIT3106 and KIA324 (U5) are common. U1 and U3 drive one transformer; U4 and U6 drive the other. U1 and U4, serve the same function on both sides as do U3 and U6.

      A first step would be to measure the resistance between all the pins of T1 and compare them to the resistance between the same pins on T2. Note that on the primary (left) end of T1 the top 3 pins are connected together as are the bottom three pins. There are probably only two pins on the secondary of each transformer.

      For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

      Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

        Before you go crazy trying to find parts, investigate a new or used one:

        http://www.lcdrepair.us/1703fps-inverter.html

        See the notes "Same As" - Samsung, Ambit

        Ebay used:

          I had this problem with my 1703fp a few years ago.

          At the time I bought a replacement inverter, I got ripped off, can't believe how cheap they are now!

          Anyway, after enough powering on/off, one of my transformers developed a nice burn mark in the side, so that would be my first suspect.

                Good to know. I'd be having a one-sided discussion with them after I got something used that they didn't tell me about upfront.

                Visa would get a call too.

                  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...

                  by Achille15
                  Hello everyone,
                  so, I have this laptop Dell Inspiron N5110 with a heating problem on both CPU (I7-2680qm) and GPU (GT 525m), I tried many solutions, like changing thermal paste every month, using thermal pads on CPU and GPU, even using thermal pads on CPU nearby coils; but nothing worked, just minutes after booting the laptop shuts itself down so I thought it might be a short problem, so I decided to check what's going on, so I went online and some tutorial (general one) said to check inductors in order to find the shorted circuit, after checking (CPU removed), I found the culprit to be...

                  Dell latitude e7470 not turn on .power buton on off and Run Power problem
                  by masoksian
                  Hi everyone,

                  I am dealing with the problem of turning on and off my Dell e7470 notebook.

                  The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

                  The system does not turn on, there is no post.

                  I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
                  The problem continues in the same way.
                  I tried to turn on the Fn key, nothing came to the screen....

                  Dell 7480 problem with freezing during the Windows loading process
                  by MahmoudNasser
                  Hello everyone, I wish you a happy day.

                  I have a Dell Latitude 7480 laptop that has a problem with freezing during the Windows loading process. If it manages to boot up, it becomes very slow and doesn't load anything from the desktop.

                  Model Dell Latitude 7480
