                      That doesn't make sense, not sure what you mean? Usually a shorted regulator will get very hot, and there will be nearly 0V on each pin.

                        I dont understand it seems to work for everyone else - even those who
                        barely speak English

                        Do you get to the screen shown in my pic attached
                        Is your pic a .jpg less than 2mb.

                        You cannot upload a file of say 5 pictures on one line you have to do a separate line for each.

                            You have a fault with your computer or application software. Are you using Internet Explorer, Firefox, Chrome or another program?

                              This bit is a test insert - dont think it works


                              I will put the same pic as attachment



                              I too think you have a fault on your PC - I have been reading - perhaps something to do with a Nividia driver update?


                              EDIT - No that didnt work

                                "Memory could not be read" is a general critical Windows error (application abort) relating to an application attempting to read memory out of range. May or may not be related to Nvidia drivers or anything else.

                                    Gigabyte GA-H61M-USB3-B3 dead short 3.3v rail to ground.

                                    Hi there,

                                    I discovered this forum through a youtuber who teaches electronic repair. I've been trying to troubleshoot my dad's old PC which is a Gigabyte GA-H61M-USB3-B3 and will not power on. I discovered a dead short on the 3.3v rail at the ATX connector so I used a bench power supply to feed 3.3v into the ATX connector and sunk about 400mA into the board (I hope that's not too much!). I used a FLIR camera to identify the problem area:



                                    The chip seems to be the following, an ITE IT8892E 1108-CXS which seems to be a PCI bridge?



                                    ...

                                    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...

                                    ASUS GU502GV not powering on - 1285A hot
                                    by yayayee
                                    Hello,

                                    I have a laptop that isn't turning on. When I disassemble it and plug in the power connector with the pcb by itself, I can see with a thermal camera I bought that TPS51285A is the only thing getting hot.

                                    So of course, the first thing I do is google the laptop model and the IC, and it just happens that I stumble upon a video by Northridgefix attempting to repair the exact same problem, only for it to catch on fire.

                                    I thought that maybe I'd be lucky so I bought a 1285A, that came in as a 1285B. The only difference I can see between them is that the 1285B...

                                    history : as always hdmi port and usb ports destroyed after unplugged
                                    after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
                                    so i changed it
                                    now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
                                    but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

                                    i don't see any projection of liquid metal on pcb.

                                    Hello everyone hope all doing well!
                                    I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...
