    Lenovo Thinkpad T14s gen2i (NM-D362) not starting up after wifi upgrade attempt.
    by acedogblast
    After attempting to upgrade the soldered 1216 Wifi module my motherboard no longer turns on. The board works before the upgrade attempt so that would certainly mean some components got knocked off accidentally but I can not find any missing components. I have thoroughly checked the whole board multiple times so lets do some tests from scratch.

    Things that currently work:[LIST][*]USB-C PD for 20V[*]Battery charging[*]VCC5M and VCC5_PD[*]VCC3M[*]VCCPCHCORE (1.8V)[/LIST]I have checked and verified that PWRSWITCH has 3.3V and goes low when pressing the power button. This is measured at...

    no display on ps4 slim ddc i2c clock shorted
    by kjchatman
    i replaced the hdmi port first with no luck then i noticed that it wouldn't do the two beeps for safe mode unless the televison wasn't connected to the console. Turns out that the ddc data bus has an issue. the clock signal is shorted to ground whenever the display is connected. Even if the console isn't plugged into the outlet. i'm not sure why the clock signal goes to ground. i removed the safety zener diode to rule that out as a culprit.

    Samsung Plasma PN59D550C1FXZA Doesn't Power ON
    by karthur
    I picked this up at a yard sale and the owner knew nothing about it. Just knew that it didn't work. I get it home and sure enough it doesn't come on. Here is what I do see/hear.

    When its first plugged in, I can hear a click. It sounds like its from the power board. There is a red light on the front by the control panel that blinks 6 times. When I touch one any of the buttons on the front panel the red light will flash. I pulled off the back cover and looked at all the board. Nothing out of the ordinary. Nothing looks burned or damaged. On the power board (BN44-00445A), there...

    ASUS GA401IH ASUS ROG Zephyrus G14 does not power off
    by tonycstech
    Laptop was hit by a lightning.
    Killed 1.8v, CPU, BIOS, embedded controller.
    Fixed everything.
    Laptop powered, works 99.9%>

    Pressing power button ONCE does not turn it off.
    I have to press it for 2 seconds and let go, then it will go into normal shutdown process.
    If i hold it any longer, it will go into FORCED shutdown as expected.

    I replaced the button, no change.
    Replaced U3201 power switch/reset logic SLG4E42553VTR no change.
    Anything else that can cause issues like that ?
    Perhaps BIOS is not legit ? I dont have any...

    Acer predator z35p no display
    by Cobblers
    I have a acer predator z35p just went off while in use.
    I have a blue power led but no response when plugging in a source.

    When It powers up I get 2 leds on the gsync pcb that flash on and off within a second of the power being plugged in. I can measure 20v at various plugs including the led driver board plug. No voltage on the tcon board.

    I found a mosfet 6679gh was shorted from drain to source on the main board so I removed it and tested out of circuit and it was still shorted from drain to source so I will replace it. It's a little bit strange though as the...

    LG 32GK650F-B random flicker
    by Wilykat
    I have this monitor that roughly every few minutes, the image would turn solid black for a frame or 2. It is infrequent but annoying and I'd like to stop it somehow. I have tried: swapping power supplies, different video cable, all 3 video inputs on the monitor, and 3 different computers. Since the symptoms doesn't change, the issue is likely with the monitor;

    Monitor has EAX69731901 board with video and power input, menu control joystick, LCD output and backlight output: [url]https://i.imgur.com/OkrBoi1.jpeg[/url]

    I couldn't find any info on repairing this monitor...
