Hi. My dad has a JVC PC-X100 that's, sadly, on it's way out, and I need a schematic to get a basic understanding of what's inside before beginning repairs. Does anyone have a link to a schematic for the mentioned stereo? Thanks!

Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

Re: Need schematic for JVC PC-X100
I just bought one and it has some wrong values for resistor values in the cd section, but for the most part it is accurate. I can send the PDF service manual if you need it? Please check your message box? -

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Hello, I have an issue with the motherboard. Specifically, it doesn't power on, more precisely, the POST initialization doesn't occur.
Let me start from the beginning, the motherboard suddenly stopped working one day. There are no beep signals from the speaker, and the debug LEDs are not lighting up. After inspecting it under a microscope and using thermal imaging, I didn't find anything that could be damaged.
After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,... -
Hi guys, I'm working on a MSI Ventus RTX 4080 16G. The GPU has 12v, 5v, however what I assume is the 1.8v rail has 1.1v and what I assume to be PEX is 0v. As you may have guessed already there is no Vmem and no Vcore.
I have looked around in related forum posts for a schematic so Much appreciated if anyone can share a Broadview schematic.
Thanks.07-15-2025, 11:15 AM -
Had one of these come in for repair with a blown battery and a WiFi issue, battery has been replaced with genuine battery (twice) and won't take a charge works fine on AC, WiFi issue gone away. Looking for a schematic so I can trace the charger circuit UM562F is only one I can find, this is the 562AI model.Had a unit come in for repair — 562AI model — with a blown battery and WiFi issue. WiFi fault has cleared, but battery won’t charge despite replacing it twice with genuine parts. Device operates fine on AC power. Suspect charger circuit fault.
