Thanks!
Thanks!

Re: N551VW rev.2.0
I found a boardview, it is not identical to what I have but it is the closest I could find it.
The problem is that the motherboard starts on the battery but not with the charger.
I changed IC Power, but the same problem. It's not a short circuit, I've tested the MOSFET and they are good. I have 19V on DRAIN but nothing on GATE.
Can anyone help me?

Re: N551VW rev.2.0
[/PHP]Hi I have same problem that this boardview is not identical. But when I saw the rev. 1.0, it exactly match with my board although rev 2.0 writing stamp on board. I suggest try this boardview / schematic. I could not find yet. If I found it share with you.I found a boardview, it is not identical to what I have but it is the closest I could find it.

Hi everyone,
I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…
In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.
The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled... -
Hello,
I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
Now I have some doubts about how to connect the new mainboard to the old power supply.
First of... -
I have a Vizio M43-C1 stuck in a reboot loop with no backlight.
I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).
Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346
So, I've ruled out the PSU for now.
The reboot loop... -
Hi everyone,
I'm trying to repair my LG 49UB850V TV (WebOS 1.0, UHD model from 2014).
Mainboard model: EAX65684604
PCB marking: EBT62954607
SPI chip: Winbond W25X20CLNIG Problem description:
Originally, the TV would turn on (backlight and LED OK if I force them on), but it shut down as soon as any input was received from the IR sensor or remote. The backlight and power board were working fine.
After testing and verifying the voltages (DRY ON, PWR ON, 12V/24V rails), I suspected a corrupted SPI firmware. What I tried so far:- I bought another

Hi
I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.
Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.
Came to learn after a bit more research...
