Dont inject beyond 1V-i told you so right at the beginning. Check All high side mosfets for shorting first and then you can inject 1.2V or even 1.3V.

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.

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...

Acer X223HQ (Version Bbd) on/off-power-cycling

by usbdevice

Hi all

There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

https://www.badcaps.net/forum/showthread.php?t=50657
https://www.badcaps.net/forum/showthread.php?t=40512

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.

It's my dad's old monitor. He...
