Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.
Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),... -
Hi everyone,
I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.
Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).
It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.
Looking at the card, it appears to be missing the following:
1x 1.0uH inductor - orange square
2x... -
Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM -
Hello. I would need some advice please.
My son's MBP suddenly stopped working and is now only getting the green-then-orange light on Magsafe and no fan spin.
He brought the MBP into the house (22 deg C) from a very cold conservatory (-3 deg C) and turned it on straight away. The Mac suddenly died a few minutes later.
I examined the logic board and couldn't find any signs of water damage, corrosion, blown up components etc. Nothing was ever spilt on it, and the logic board looks immaculate.
I have already replaced the logic board with another... -
Hi everyone, I hope you are having a good day.
I have a laptop sony Vaio, DA0HK1MB6E0, MBX-247. REV: E
The laptop suddenly shut down as the owner told me, so I did the normal check there is no short but the laptop it's not powering up and there is no light when I connect the adapter because there is no battery.
so I checked.
