Hello everyone, I got a laptop with a weird issue, so I looked for schematics, and now I'm here. I will look for similar cases in the forum, or write my own post if i have not found any similar. (Partial backlight damage of A2337, where only the bottom backlight works, and only on high display brightness.Comment

Hello, my name is atm959 online, and I work as a technician, doing pretty basic repairs of phones, tablets, computers, and game consoles (mostly phones though). I love to learn, and I love programming and technology as a whole. I plan on learning more in-depth repairs, and have recently learned how to replace PS5 analog sticks, and the same procedure should also apply to XBox controllers. It is nice to meet everyone! (I'm not good at introductions lol)Comment

Hello to all! Just popping in to introduce myself as the, as of this posting, freshest capacitor here. I'm sure I'll be old news quite soon as it appears new members sign up quite regularly. I've been into electronics for as long as I can remember and often stumble across this site when trying to find information about niche stuff. Finally made an account. I tinker with pretty much anything and everything that comes my way, whether it be a toaster, or some newfangled piece of cutting edge tech. I'm pretty good with the hardware side of things, but struggle with software. Anyway, I look forward to exploring all the site has to offer and chiming in when possible. See you all around!Comment

I'm miphonematt, once upon a time I was bonhomme, but that was decades ago when the internet browser of choice was links/lynx and there were no pretty pictures to look at. I've been in and out of the scenes of PDA ROM development, iOS/Android App Development and various rooting/jailbreaking/device hacking forums. I'm still fairly inexperienced when it comes to desoldering with a hot air rework station but i'm here to learn and share my experience and knowledge. I'm originally from Phoenix but now I reside in Denver Colorado.
Thank you for allowing me to be a part of your great forum/siteComment
