by r2digitalI have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...04-18-2024, 03:50 PM

by mrgumshotHi all,
I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.
After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.
I hope someone can help me out. Attached is my [B]ORIGINAL...-

by shlomim412Hello
working on a2141 macbook, board number 820-01700 which has no wifi\bt and also no connection with LAN cable.
initial visual inspection the board looks good no visible corrosion or damage.
i found that PP3V3_G3S_X is shorted to ground (around 1.5ohm short)
and also PP3V3_GS3_WLAN i shorted to ground (same ohm reading, around 1.5ohm).
the board is working but no WIFI\BT as i mentioned.
with the usb c cable connected for measurement i noticed U8215 i getting EXTREMELY HOT

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.

by werinqHello, recently I encontered an issue with my BIOS, it just corrupted out of nothing, it all happened after I just shutdown my laptop. I tried extracting the BIOS from the .exe file, but no succeed. I followed the guide attached to this topic, but it didn't help me. I tried using different BIOS dump files from this topic, but none worked. So this is why I ask to have BIOS dump file, so I can reprogramm it.

My Samsung Galaxy Book suddenly stopped working and won't turn on at all. I noticed that the component in the attached photo looks burnt out. I think it's a voltage regulator, but I can't find any information about this IC online. I've searched using the code on the chip, but I haven't been able to find a replacement....Today, 03:30 AM
