    Dell E151FPp

    I recently rescued a Dell E151FPp on it's way to the dumpster. Upon plugging it in, it appears that the backlight on this unit is non-functional. I was reading these two posts:

    And it appears that the problem is likely just a blown fuse. Unfortunately, I have no idea which one is the problem. I can see that right next to the power socket on the power supply board there is a 2A 250v slow-blow ceramic fuse, but then there is the infamous F1 fuse next to the connector on the inverter board. Which one should I replace?

      the one on the inverter, but better to test for continuity with multimeter if you can put your hands on one, If fuse blown then you will have no continuity across fuse, If multimeter has buzzer option then there will be no buzz if blown

          Alright, well I finally found my multimeter and every fuse on the board is fine except that pesky smd-type "F1" fuse. Looks like I know what I need to replace.

              Sometimes fuses blow for no apparent reason, but a shorted transistor can also cause it.

              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.

                  Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
                  by Babbar
                  I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

                  Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

                  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...

                  HP X360 convertible battery blown fuse error, not charging

                  HP Modelnumber: 14-dh0061nb​
                  This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
                  The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
                  I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
                  And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
                  All these 3 batteries are charging...

                  Carver CM-1090 - Power relay clicking on & off, then fuse blown after 20-30 seconds of power cycling.
                  by beetle1303
                  I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.

                  On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off...

                  Samsung UE46ES8000 Blown fuse but no other signs of short
                  by jesterace
                  Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...
