Hey guys! I've recently found out this amazing forum where people talk and discuss about electronics repairs and i'm actually amazed with everything that here's have to offer.
Oh well, i came here looking for a simple bios file in order to get my main laptop working again, but after a while trying to figure out what the hell was going on, i'm quite concerned that it would be worse than i tought. I was fooling around with Mr. Smokeless's UMAF BIOS mod, looking for a way to enable CSM compatibility and legacy boot on my device.

Hi fellow lifesavers.
I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.
Checked the socket, the plug fuse, all good. Took it out to examine the boards.
There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.
I've been trying to examine the main board, but it's a bit difficult becuse...06-06-2024, 09:11 AM -

Hi
I need the value of C102 .
[B]Briefly[/B] : Blown Fuse . In-Series lamp lights fully = short on Hot Side - Bridge DC [U]Holes[/U] are shorted !. Bridge OK out-of-circuit. Chopper Mosfet and Diode - OK. D102 ( T4 Diode ) measures In-Circuit 0.041V both ways but Normal outside. Other caps / diodes..ok. Short remains Haarg .
BUT ! , when C102 Cap ( between Main Cap legs , it doesn't show as I took it out for easier access ) was taken out - short is gone .
Thanks a bunchHi

Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB. On a new memory it shows me 3776MB. From what I found on the Sony page, the following models could also be compatible:
KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B,...Yesterday, 04:13 PM -

I started troubleshooting this Razer Blade 15 laptop DA560 motgerboard a while back, due to some shorted 19v, 5v, 1v power rails. I fixed some of components and think 19v rail is good, 5v rail is good, 3v is better but not all way i think, and 1v is still bad. At this point the diode reading on these rails are 19v - 0.032v , 5v - 0.167v, 3 - 0.63v and 1v - 0.005v .
When the rails when down, I went down different rabbit holes and seeing chips getting pretty warm on thermal but not blazing hot. Yet there were not any caps or any small components getting blazing hot. Example is EC chip,...06-06-2024, 11:35 AM

I am still working on an Lenovo e14 AMD notebook with some problems. The laptop booted normally but had a ton of problems with the soldered ddr4 memory. I tried deactivating the memory via bios, but that didn't work.
As i have a matching donor here, I decided to change the module i suspect to be faulty and exchange it with one of the donors.
Did so, but now the laptop won't boot anymore.
Anyone here who already did that and can comfirn, that exchangeing one module alone would work? Or do I need to exchange all 4 of them to make it work?Today, 02:42 AM -

Hello everyone!!! I recently got this Philips Smart TV model 43PFL5766/F7 E without power. After some troubleshooting, I found a short in the main board, while injecting voltage noticed a component getting hot, removed it and voila! short released. I cant find any information about the component I took off it reads FZN 910. I'm attaching some pictures of the component itself and the board for reference. Any help or suggestion is really appreciated ....Today, 09:49 AM
