This thing on rare occasion will turn on for a split second, most of the time just have a blinking LED. Fuse F601 and PF751 tested good. 164V across the input cap. Diodes D751 and D761 aren't shorted. I think the problem is either with the caps or the voltage regulator on the main board. That regulator U10 (which reads G061 950T65) acts very strange:
Pin 1: Bounces between 0.985V - 1.300V
Pin 2: 0.00V
Pin 3: Bounces between 0.980V - 1.060V
Could that be one of the caps next to the regulator? All the caps in this thing are trash (It is a Benq afterall...) The power board has Lelon/Elite and the main board has Lelon/Jamicon/Elite

by BowlineMy question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
by DanPokaI bought this p2210f dell monitor to fix. Schematic is the same as p2210.
Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...-

by artvandalaiThis Concept 2 rower pm5 monitor doesn't shut down. It keeps turning on and stays on after being turned off. I read on another forum by another user that replaced the same component to check the voltage regulator.
The monitor should pull around 35mA when turned on and in shutdown it should drops to around 0.060mA. Any advice on finding the voltage regulator on this board to check if it needs to be replaced?

by Jesus CoderHello everyone,
I have been having some difficulties reviving an old Dell 2408WFPb PC monitor that I received for free. When I first acquired it, the backlights of the display were on but alas no image was showing. After extensive research on the topic, I went ahead and purchased a new t-con board for the monitor. After installing the board, I was then presented with a new screen that was half black and half green (more so black). I have been unable to figure out what to do next as I have limited knowledge of display electronics. Might anyone on this forum have an idea of what may...-

by deep000My computer monitor ASUS VP249H stopped working, and smoke came out of it.
I opened it and found that a voltage regulator had burned out.
The problem is that I can't identify its reference.
I searched online for schematics or photos of similar boards that people are selling, but without success (no schematics, bad quality of the board or lack of the reference when it's a good quality 😅).
How can I find its reference, and do you think it's repairable?
Monitor: Asus VP249H
Board reference: 0171 - 2271 - 6083
Thanks
