by grimacelordHello,
I have an HP 14-dq0055dx laptop here that came in for boot looping. It was previously taken to another shop and they tried flashing a BIOS firmware to the chip, so I cannot take an original dump. For a second or two, a message will come up on the screen that says:
This loop will go on for as long as you like. I let it run for about 12 hours and came in the following morning and it's still looping.

I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...04-22-2024, 11:28 AM -

by vanromicHello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.
Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.
The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.
I've read that the CD3215s are...Today, 06:46 AM -

by cassiusI'm looking for ways to ensure that my desktop computer automatically powers on once the power is restored after an outage. I've heard suggestions about shorting the front panel I/O connector on the motherboard or shorting the SMPS 20/24 pin to accomplish this. However, I'm uncertain if these methods are both effective and safe.

by SupradinHi everyone. I'm new on this things, this is my first amplifier after I start offering repair service almost for free, just for learning purpouse
So I have a amp that is going to protection mode. I saw that if I remove the ribbon cable which sends from main board B+,B- and signal for amplifiers card, is not going to protection mode.
So, from that ribbon cable y disconnect everything but b+ b-, and amp goes again to protection mode. So my guess was something is wrong in the amp board.
I disconnect all transistors and amp is ok.
After, I connect the...-
