anything M with C1 at the end would work giving some hints
.. it looks like another motherboard yet again .. did reflow with rework gun and very little changed .. the bottom processor turns on but the top one only at random along with the T-con and no backlights .. also looked at the buck converters and regulators on the mainboard .. they look to have normal voltages .. the white power light on the bottom corner flickers at random .. sometimes it turns on sometimes not when I cycle the AC supply
.. next ESR on caps and look for shorted MLCC's .. not having a schem or... -
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... -
Hi everyone, I recently acquired an HP EliteBook 840 G4 (6050A2854301-MB-A01) that I'm hoping to bring back to life. I'm fairly new to laptop repairs but eager to learn and willing to put in the effort to understand and fix this. Any advice or guidance would mean a lot!
What Happened
The issue started when the laptop was accidentally plugged in with reverse polarity. Before this incident, the laptop would show a power/charging light whenever it was plugged in. However, now it's completely unresponsive—no lights, no power, nothing. I've been doing some research and understand... -
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.
