Read from a board which had a borked SRM installation. It still entered U-boot on serial so I believe this dump is OK.

Hello everybody,
my TV has a problem. It keeps turning on and off. The speakers are still working, and I hooked up the TV to my PC, and it recognizes it as a Samsung device. I am able to get a stable backlight when I disconnect the cable(I believe it is called the LVDS cable) that connects the left lower board (which is connected to the "main board") and the right lower board. I have tried a taping method I saw on YouTube, where the CLK cables are taped off. In fact, I proceeded to figure out which pin I have to tape off in order to get a stable backlight. It doesn't matter...10-14-2024, 03:45 AM -
Hi, I'm trying to fix my buddies rechargeable led work light made by olight and the model is odiance. For some reason now after a couple years of no issue, when powered off now, the led is faintly lit on 3 of the orange rows but as you can see from the first pic that's not where the leds are. The part that is faintly lit is beside the leds? Anyone know how that is possible? Is there small voltage still coming in somehow? The third pic is with the cover off....10-13-2024, 10:33 PM

I’ve got this Ancel BA-101 battery tester for a few years now and discovered an issue testing flooded car batteries. The damn thing reads always low compared to other battery testers. I mean low in the tune of 25 to 30%! AGM’s read comparable within margin of error. I wonder if all these have the same problem or mine is defective somehow?Yesterday, 09:38 AM

Hi everyone.
I have here a Lenovo laptop, model Ideapad Gaming. It works, but dedicated Nvidia GTX 1650 is not detected. Also, the computer turns on with fan on full speed and I receive errors when trying to install Windows.
On troubleshooting, the conclusion was the GPU was gone.
Is there any way I can completely disable the dedicated GPU and use only the Intel one? Maybe on doing that the other issues will go away, too. Fingers crossed.
Any help is appreciated.
Thanx....Today, 03:44 PM -

Hi, Recently my Samsung 4K QE55Q60AAUXXH just suddenly stopped working_ there is no any sign of life - no red light or anything..and think, after diagnostic, it is diode DM863c SF28e PK33 siyu or one of these four. Is there any alternative I can replace with since it is hard to find it in my country and to order outside is quite difficult. thank you...Today, 07:35 AM

Hi,
I have something I've never seen before.
I've received an Asus laptop that had a short in the DC input. I found that the second MOSFET in the DC input line was heating up, so I replaced it, and now the laptop works. Great, isn't it?
Now, for the odd part: the mosfet replaced wasn't measuring as short or having low impedance on the board either before or after I replaced it. It was an "A5 GND" mosfet, which I swapped for something I had in stock—some N-type 30V MOSFET.
Now the laptop works fine, but when it restarts,...Today, 12:23 PM -
