Re: Toshiba Satellite C640 No Power Need Help
Ok. The black probe I put on the screw part on the mobo assuming it is the ground and the red probe I put it on the 3r3 135 b3p terminal (both of them one at a time)
Refer the attachment.
P.S. The below resistor labeled L6200 with black font was actually L6201.Attached FilesLast edited by tiubxray; 07-03-2014, 09:57 PM.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

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

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.

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.

Hi guys,
So, I've been racking my brains on this one.
I have a Satellite C50-A which I'm repairing for a friend.
I recently replaced the main board due to failure.
Following this, absolutely everything works perfectly, except for the fact it won't power down.
Initially, shutting down via Windows would shut the OS down, screen would turn off (noticed the lighter black go to what looks like the darker black powered off screen as though the backlights have powered off), however the laptop was still running internally with a spinning... -
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... -
