      Images of the boards I cant get on SJ ? Also check how to test the Led backlight voltages sounds to me like a failed Led.

          Thanks reeceyBurger; well i send some pic of the power supply and showing the 2 pins that i tripped and toughed together making a small burn,on the 24v and GND,before i open panel to check for any burned led ,i would like to know what to check for the 24v that were there before i shorted these connections,where is the 24v regulator,i checked all the regulators in circuit with Diode check and they seem to be ok any clues before i go to led panel will be welcome and appreciated, sorry for the pics that are not very good due a crappy camera.

                  How can I be sure that my EC chip is dead?
                  by double_DD
                  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...

                  Help with Samsung Microwave Cooling Fan Wiring Pins
                  by jkucukov
                  I have a Samsung Microwave I'm looking to harvest some parts from, specifically the 120V AC motor that keeps the Magnetron cool.
                  From the image below, we see 3 pins on the AC motor, with AC Voltage tester all 3 leads measure 120 V with the microwave plugged in and fan not running. With the fan running only pins 2 & 3 measure 120 V.

                  What I'm looking to do is wire this motor up on a Air Compressor to keep the motor cool, but I need to know what is the safe way to wire it, (IE wire in pins 2 & 3 with 120 V only to get it to run?)

                  Also, as its wired, when...

                  Where to find a very small fpc connector 0.3mm between 2 pins ?
                  by corrize
                  Hello, I search this connector (oxydated).
                  It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
                  I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
                  I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?

                  Do you know how to find this connector please ? What is the exact name for find it ?

                  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 ...

                  My first attempt at board repair - Asus Prime X670-P
                  by tiagooliveira95
                  Hey everyone

                  I decided to dive headfirst into board repair. I'm a computer engineering student, and I'm attempting to fix my first board.

                  I have made some progress, and I feel super excited. Still haven't fixed the board tho, but I decided to make a post here to share my progress.

                  This is an X670-P, seller stated bent pins and no power on, the socket has 2 bent pins, the pins are slightly bent upwards (VSS and a Channel A pin), so it's an easy fix, don't even need to replace the socket, tested all power rails on the CPU and found no shorts, the bent pins...
