    hp dv5-1000 / 482870-001

    Hello,
    the problem is driving me crazy; lcd panel does nt show splash screen of bios, works only when enter in svga mode, but screen dimension is approx 1/3 of panel, external monitor works as expected.

    Done reflow on the nvidia gpu, still defect; what do you thing graphic chip is dead? or could check something other on the board?.

    Thanks.

      If external monitor works ok GPU is ok, screen is faulty.

          Sorry, forgot to say that already tested with another panel and inverter: same result.

              Then you have some driver circuitry bad between the GPU and screen. Not worth fixing. Time for a new board.

                      your Nvidia chipset get fulty . u have to heat 150 digree C from SMD workstation . it wil solve your problms

                          No...

                          DV5000 was Puma platform, or Radeon 3xxx IGP. A very good platform. There are reports of some of these needing reflowing, but no failures outright

                          The only chip so far that I have never seen that needed reflowing is the Intel GMA 3000 and 4500, and the ones with the GPU on the CPU should be even less susceptible.

                          I wonder if Llano will also be GPU on the CPU die.

                              Purchased a spare mobo; @ kiranfocuz 150c is not enough to reflow pb free...take a look at this post https://www.badcaps.net/forum/showthread.php?t=14852 best regards.

                                              by CapLeaker
                                              Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

                                              Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

                                              by rounin
                                              Hi everyone,

                                              I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                                              🛠 Original Issue
                                              The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                                              Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                                              I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                                              ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                                              Hello mates,

                                              I bought this subwoofer a few days ago used and blind and it works erratically, as far as I could see, it has been tampered with, the speaker is not the original one and of 8 Ohm when it should be of 4, and there are some welds like reworked by the boards.

                                              It doesn't have much power (expected more from it) and it distorts if you increase the volume over the middle, maybe it's because of the high impedance of the speaker. The problem is that it has sound when it wants, the led panels all work correctly, you can hear the power relay on power on, but right now...

                                              Hey ya'll this is my first post on here. I recently aquired a used/broken 2019 mbp 16 a2141 with the 820-01700 board. Seller told me that the laptop needed a new lcd. However upon doing some troubleshooting i found out the lcd is fine.

                                              Laptop boots like a normal, plays chime, touchbar lights up however there is no image on the internal lcd. If i connect and external monitor while its already on, nothing happens and no image is displayed on external. However if i restart or boot the machine while its plugged in, the external then works and a backlight is now visible on the laptop....

                                              Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

                                              I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

                                              So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.
