Re: cyperpowerpc fangbook hx6 not powering
Theres no IC on that part of the board. Look at some more images for reference . My mistake ,there is,unless theres different revisions.

The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
Hi,
I recently bought an ASUS ROG STRIX B550-F GAMING motherboard that was listed as "dead, not powering on." However, it does show some signs of life. I've performed several basic measurements and would like to share the results.- The board enters a "ready to power on" state after plugging in the PSU.
- Pressing the power button increases power draw.
- Sometimes, touching the RSMRST_L pad with a multimeter probe causes the board to shut off and return to standby.

Hi All,
I'm working on a MacBook Pro A2442 (14", 2021) that's not powering on. On two out of three USB-C ports, I get 5V and the current briefly ramps up to around 0.210A before dropping to 0.036A. On the third port (JF600), I only get 0.0045A and it stays there.
Initially, I suspected a faulty CD3217 on that port, especially since I noticed signs of previous liquid damage near the JF600 USB connector. I replaced the CD3217 with an UF400 (from an A2442 donor board from the same location). According to the supplier, this should be a compatible version, but the behavior... -
Got it for free on marketplace because it stopped working after a storm.
When I began troubleshooting the power supply, I fried 2 fuses and a mosfet by shorting 2 pins on accident, but I've replaced those components.
The tv had a soundbar connected, which was also killed by the storm. On the tv side I found a transistor shorted on the hdmi 2 (arc) and a lot of capacitors shorted on the main board.
Disconnecting and reconnecting the psu to main board cable, while still being connected to 120 V AC, would wake things up, such as a red light from the optical... -
I have this surface pro 5 that is not powering on, but it charges the battery, power connector lights up and battery is charged. power button has 3,3.
These coils are shorted to ground. It's the +3P3VSB and +1VSB.
There is 15v, 10v, 8.8v, 3.3v present on the board.
Tried to inject voltage in those coils: 1v 3a but could not find the short because lots of areas heat a little.. and I don't have thermal camera..
Any ideas?
Thanks.
