Hello. I need if someone can help with this model of laptop. The mainboard is DA0Y0MMBAJ0 and i need schematic or boardview.Thanks.

Hello. I have a Samsung qled model QE58Q60TAU.
The TV restarts continuously and without an image. If I disconnect either half, the TV does not restart, but in both situations I have absolutely nothing on the display, only the backlight is on. I checked the CKv signals and the rest VGH, VSS etc. I measured them against the ground and between them and found between VGH and VSS a resistance of 106 ohms on the B side of the screen (right). I isolated all the signals on the right side and covered them with scotch tape and absolutely nothing has changed, it doesn't restart but I have no picture...

Yes, PL700 and 1.0V is shorted to ground, and thats the end of story. Thanks.

Hello.
I need help with a laptop Dell with LA-D801P motherboard.
The laptop completely died, no power, no leds.
The voltage of 19V is present at the output of the second mosfet.
The voltage on Pin 9 and 19 of PU102 is 0V.
Voltage on
PU100 :
pin2 =19v
pin11 =4.16v
pin12 =0.18v
pin17 =0v
pin19 =0v
I have 0 ohms on the coils PL100, PL301 and PL700.
If I remove pjp102 the short remains on the side of +3VALW.
Then I removed pjp501 and pjp801 but the short did not go to the integrated PU500 and PU800.
Then I checked...

I have a problem with an HP laptop model 250 G5, mainboard LA-C701P. The integrated PU2 is ok, being replaced, but the problem is with the 3.3v LDO voltage, the 5.5V LDO being ok. On pin 15, instead of 3.3V, I have 3.16V and a consumption of 150m, the integrated only supports 100mA, it gets very hot. I injected 3.3V on pin 15 and the consumption remained at 150 mA and there is nothing hot under the thermal chamber. I disconnected the resistance towards pin 125 from the integrated UK1 and the consumption dropped to 0, and I assumed that the consumption is from the integrated. I replaced it with...
