Can anyone please tell me the source of +5V_VCC1 on the schematic attached with this post.

Hello There,
As subject line suggests, can anyone provide the schematic for the same ?
or can anyone through some lite on the IC/MOSFET/BUCK number ( pictures attached )... -
Hi there!
Im trying to service an old Harman&Kardon tape deck (TD470) player, which after being put away for many years, is now lacking sound randomly (first time I tried it worked, called the owner and said it wasn't working for him, tried again myself and sound was gone)
This intermitent issue led to to go straight to the PS & Caps...I found at least one voltage missing (sorry now I can't remember which one), and one of the 3 fuses in the PS was open (this is strange as an intermitent failure wouldn't relate to a blown fuse).
First thing I suspected... -
I have bought a not complete and defective Dell Latitude 5520 for parts (needed the networkconnector (RJ45) to repair a other board).
Have repaired the other board (Dell Latitude 5540) and I wanted to know if I could find out what is wrong with the 5520 board (SouthPeak15 TGL MB 8L 19819-1) and perhaps repair this one also.
After connecting the USB-C charger (both USB-C ports on the laptop, does not have an other option) and pressing the power button, nothing happens (no lights or fans, no capslock).
Have checked with a thermal camera, and there are a couple of things... -
Can you anyone explain what should be the ideal voltage for PROCHOT according to this schematic.
I have no voltage on AD_IINP.
On U8801 I have 5V on pin 5 and 0.537 volt on pin 3. No output voltage.
Currently board is not triggering at all.... -
Hello Im new and I have a problem with a msi gtx 1060 6gt ocv1
When I turn the pc on, after 5 - 15s the gpu will shut off and the fans will go 100%.
The psu is not the problem because I have testet it in other pcs and it even shuts off in bios.
I think the problem could be 5 capacitors missing on the back side,
but I cant identify them because they are made of ceramics and are not marked in any way.
The gpu Im talking about is this one: https://www.amazon.de/MSI-DL-DVI-D-A.../dp/B01KF90IY8
But when...10-25-2025, 03:49 AM
