Lenovo IdeaPad FLEX 5-1570 81CA totally dead
Hi, Does anyone have the boardview for Lenovo IdeaPad FLEX 5-1570 81CA LA-E541P. Schematics is posted but I need little help finding the components. The motherboard in this is CIUYA/SA/SB/SD LA-E541P. I am not getting max voltage on pin 1 of this chip PU703 ISL88739HRZ, getting only 2.254, is this voltage correct for the chip to operate??? Before this there is a resistor PR729 392K, I want the location of this resistor. Any help will be greatly appreciated. ThanksComment

Re: La-e541p
I found the resistor & across this, on both ends I am getting 2.25 volt & on the other end it 19V which is correct. The resistor value is correct 392K. The N-Channel MOSFET PQ740, Drain I am getting 19 volts & on the Gate there should be a high voltage but here the volts fluctuates from .25 to .75, bouncing up & down & zero volts on source. Here I should get nearly 24 volts. Any tips will be a great help.Comment

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 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.
