    Thank you sir Can you also find value of some resistors if I'll tell you their numers on the PCB?

        I'm going from my photos, as I no longer have the monitor.
        I can try, but no guarantee.....

            Ok that's is too small I am afraid. I'd even have problems reading it from the SMDs itself and you only have low-res photos…

            Infortunatelly I am afraid they are shorted as I read strange values and they are burned…

                The resolution is fine, the problem will be whether the focus and lighting will be ok on the part of the board you need.

                    Very well sir, I need R614, R612 and R623, too. Unfortunatelly, that part is blurred and shines too much for my eyes.

                        I checked my other photos, they're all a tad blurry in that spot.
                        I must not have had the camera sensor plane parallel with the board so the DOF was lacking on that part.

                            Guess too low shutter number. I am trying to use maximum whenever possible…

                                Well if I used maximum shutter (1/8000 sec), and a small enough F stop for DOF (F8 even)
                                I'd need one hell of a bright light.

                                    F8, no need for short exposal time. Actually, with stand, you can take sharp photos even at 1 second exposal or so.

                                        Yes, I was joking. I do actually know a thing or 2 about photography.

                                            In addition to changing the C5707 transistors and MOSFET Fu9024, also changes the capacitors gray interposed between loro.vedrai you solve the problem.

                                                Or maybe if anybody knew where to find schematics/service manual?

                                                    BenQ 3501R turns off after 1-2 seconds
                                                    by kalemaroni
                                                    The capacitor on the board was slightly bulged at the top so I replaced. Unfortunately the cap I bought on eBay was much thinner than the original, even though the spec was the same (4.7uf 100v). The problem persists. Would the thickness of the cap actually make a difference - is it worth trying to find the correct one?

                                                    Hi,

                                                    I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...

                                                    Hi all,

                                                    I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
                                                    I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

                                                    I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

                                                    I have tried a few new bios but exactly...

                                                    Hi all,

                                                    As the title suggests, how can I be sure that my EC chip is really dead?

                                                    I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

                                                    Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...
