    VX922 Power LED flashing

    Hi, new to caps and everything but I've been reading around and it seems to be common for a viewsonic VX922 to have the flashing power LED problem due to bad caps.
    I've taken out the power board etc but have no idea how to identify the bad caps, could anyone help an electronics newbie out? It'd be much appreciated!
    thanks

      Hi Tuckertime,

      Welcome to Badcaps.

      Do you have a digital camera to take some pictures of your board?

      I remember there are several caps near the top of the board (hold it vertically like how it is installed in the monitor with the ac jack on the bottom), these caps get baked over time by the aluminium heatsink.

      These are probably around 1000uF.

          As suggested, post pictures. Also, capacitors can fail without any visible changes (swelling, leakage, etc.) I STRONGLY suggest replacing all caps, rather than trying to replace only the likely suspects. The additional cost is minimal (under $5), the reliability gained is significant.

          If you are't sure, post the voltage, value, and series, and we will suggest replacements.

          For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

          Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

                  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.

                  Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
                  by STKR123
                  As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
                  I wonder if re-flashing the BIOS might be of any use here.

                  As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

                  There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

                  Heathkit IO-4205 Power Supply Caps
                  by eryjus
                  Hello,

                  First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                  I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                  I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                  ...

                  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...
