Hello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

Hello,
I recently got a PS5 with an EMD-032 board and someone before me “tried” to change the HDMI port. Unfortunately, a few SMD components are now missing, see image. the top one should be a 100nF cap. but what is the lower (0Ohm resistance?)

Hi,
I've got a problem with laptop Asus ROG GA503R, laptop power on (it does take a while) show asus logo and then it stuck on the black screen noticed that laptop goes to windows. I've tried new LCD, no difference, I can go to BIOS, laptop would stay on can change options etc., tired boot it externally with disconnected LCD and it only display on BIOS, attempt to boot to Linux, same problem.
I would provide with board model tommorow....Yesterday, 04:15 PM -
I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.
I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.
Does anybody have any insights?

Hi,
I am trying to help someone to repair a mac mini A1993 820-00939.
The mac mini won't power on.
Voltages on U7800 are all good except
PP1V2_PRIM 0v
PP1V_PRIM 0v
PP5V_G3S is missing too
Someone has the power on sequence of this ?
Thank you on advance.

Hi,
I have this dead laptop, if I plug the charger I see only charging led light blinking 3 times.
I disassembled it, removed the battery and checked with my multimeter:
red arrow input connector 19v
green arrow first mosfet drain 19v
white arrow first mosfet source 3v
yellow arrow second mosfet 19v
pink arrow 3v
blue arrow third mosfet shorted to ground
current resistor 3 volts on both sides
Any advice? I have a thermal camera and I could inject low voltage if needed.
Thanks...Today, 01:24 AM -

Couple of Windows 11 machines have come in this week with the same issue. After you login, the taskbar will not appear (or just be a black bar). No access to Start Menu. Task Manager (use CTL+SHIFT+ESC) works, however the Performance stats seem stuck with CPU on 100% for Task Manager itself. Trying to exit Task Manager result in it hanging as well. No issue if you boot into Safe Mode.
First machine, tried many things to no avail (System Restore from last Windows update, rebooting in Diag mode, trying to reinstall Windows Apps via Powershell). In the end, I did an in-place upgrade...Yesterday, 10:16 PM -
