Re: ViewSonic VA 1912WB
Welcome to the forum! There are a few issues that require attention before most members will help:
1) Please be more specific about the symptoms. Telling us there is no display isn't very helpful. Saying that there is an image for a few seconds before it goes off, that the power light stays on, or there's a flash of light, ticking sound, etc is VERY helpful. Any observations you provide can only help us help you.
2) Photos are always good, but we need to see the entire board, top and bottom. Use natural lighting and try to get the best focus possible. Remember, we're not sitting next to you and we have to see what you're seeing in order to provide test instructions.Comment

Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected... -
Hi
I was hoping someone could give me some advise. A friend dropped off an Xbox Series X for repair—normally not something I deal with, but I'm helping out as a favour.
Currently, the console powers on with a beep and then immediately powers off. On closer inspection, the HDMI port clearly needs replacing, and there's significant liquid damage/ missing components.
Before I go down the rabbit hole of sourcing a donor board and replacing damaged components, I wanted to ask: based on the area I've marked in the photo, do you think this could be what's causing... -

Hi all,
title says it all. I have Airpods Max which no charing light. Reset lights show up when i connect a USB charger and push the buttons but not loading or bluetooth reaction. USB meter shows 5v, 0,6a and 1,8-3,2w (differs on used charger).
The videos i found about repairs are more something like a try and error with changing parts or battery replacement but no direct fault analysis.
So maybe anybody here has experience in repairs or can help me to locate the problem? My stomach tells me that i need a new battery but 50€ for a feeling is too much.
