    Re: LG 60PC1D 60 inch plasma tv no power

    With PSU Disconnected from Y-SUS/Z-SUS, What readings (resistance) do you get, -first from VS connections of Y-SUS, then VA of Y-SUS to chassis? Also, Check fuses of both Y-SUS/Z-SUS boards.....

    --Same test for Z-SUS board...

    What board is this mystery 10 ohm 5W resistor on?
    TELEFIX

        The resistor is on the pfc/standby board. I replaced this resistor a few days ago as it was open circuit. Too much current killed it. I will check the resistance, thanks.

            Hi, did you solve this problem. I have the same symptoms. Standby ok, but fails to bring up the Vs. Have already replaced that 10ohm,5W resistor on the standby board (was open) with a substitute as I couldn't find the original part locally. Measuring the PFC voltage at P217_2 connector and it reads about 325VDC momentarily when I hit the power button on the remote and the relays cut in for a second(compared to about 380VDC measured on a known working TV.

                Does anyone have left over boards from this set?

                    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                    by Tynan Dill
                    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                    Upon bringing it home and plugging it up, it showed a standby light.

                    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                    The screen seems to blackout and stay black, but with a flashlight I can see the display.

                    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                    Assuming...

                    Microsoft Surface Pro (5th gen) model 1796 - no power
                    by PantherDave
                    Hi all!

                    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                    Asus Probook P5440UF-XB74 power issue
                    by GLISIT
                    Hi all,

                    TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                    I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                    A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                    Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                    by sam_sam_sam
                    I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                    One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
