          if you are going to reflow then best to bin it rather then waste time.

          reflow without industry equipement is asking for trouble.
          million answers all over the net the laptop will die soon or later so why bother?

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  Assuming...

                  Dell inspiron 17 (7786) - DP/N 09P7JP - odd power issues, starting with no power LED
                  by zlr8r
                  hey guys, hoping for some pointers to repair an eBay bought "faulty" laptop.

                  Ill try and give as much info as I can.

                  Bios: 1.9.0

                  When I received this , it would only flicker on the KB backlight for a second, then off and on.
                  Then it started getting weirder!
                  Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has...

                  Dell Optiplex 7490 AIO - red power led after flash
                  by Mark01
                  Hi guys,

                  This is my first post! 🚀
                  I have no idea what I’m doing, but I’m learning by trial and error.

                  I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...

                  Dell XPS 9380 No Power - After providing 3VALW and 5VALW once, they persist - still no power-up
                  by seppde
                  Hello everyone,
                  I've recently gotten my hands on a defective XPS13 9380. I will attach a zip of the schematics and boardview.
                  My first discovery on the Board was that the reverse current Diode PD103 of the 1st USB-C was blown.
                  Nothing to worry about, the board got 3 USB-C ports which support Power/Charging. On I go.
                  Next I inspected the power-rails to see why the diode blew up and found a short on the 3V3 rail which I traced back to the Power-IC for the LCD (UZ2). I desoldered it and the very low-ohmic short is gone. I checked on the LCD-connector that there's no short...

                  Dell G3 17 3779 Weird power cycling and shutdown/restart issue
                  by SuperJames
                  This one's a weird one, and still unsolved despite it having gone back to Dell once.

                  Specs

                  i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

                  Backstory

                  I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...
