    dell la-C361p no video power okay

    hello
    so i got this dell xps 15-9550 la-c361p board and the power IC for vccgt was burnt AOZ5019, Replaced it i get all voltages cpu and also gpu voltage 0.9v and vccgt 0.7v.Now i believe this machine has common issues.it power on and then i can see keyboard backlight ok.Also when i take off the ram it gives me ram led error.another thing when i press D and power on my lcd gives a test RGB pattern.I have changed the bios, also i see activity on the oscilloscope the data input and output try to say the cpu wants to fire up.The intel me flash tool used is 11.0.0.1178 which i cant find .i have the flash tools 11.0.0.1173 but it gives me errors.
    Anyone solved this issue with this model.or and ideas what to look for.
    thanks

      Most likely damaged graphics engine inside SOC due to burnt AOZ5019. In such cases, it always feels like display is about to come but will never come. Usually ,when GFX voltage is constant on SOC board,thats an indicator of damaged graphics engine inside SOC. have faced it on dell inspiron 3567. After replacing the SOC,display came. may be your case is not same as what i experienced but worth noting the point.

          Gpu DELL OEM RTX3080 No video
          by PacoGT
          Hello friends, I have a question. They brought me this video card, a DELL RTX 3080. They told me that it fell and the impact no longer produced video.
          When trying it, it's as if it wanted to give video but in the end nothing, I already checked voltages etc. everything is as it should, but without video
          I suppose it could be a bios problem but since sometimes they don't tell you everything, I've searched for the bios everywhere but without success
          I can't find a backup or something to try to reprogram bios and see if it's the fault, could you help me maybe someone has one that...

          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
          by Bowline
          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
          I have tried multiple different Dell power adapters. My Dell...

          DELL LATITUDE 5420, ST 20TFKN3, LA-K491P REV:2.0 (A01) powers on and die about 15 secs later, no video
          by Chivo77
          hello friends, I have a DELL LATITUDE 5420---MODEL P137G, ST 20TFKN3 LA-K491P REV:2.0 (A01) and its quite a challenge. It powers on with the battery disconnected, lasts on for about 15 secs, and then shuts off. It does the same with battery only (no adapter). With battery and adapter it sometimes starts after hitting the button several times. It displays nothing in every case. Since only the Boardview is available, I guided myself with schematics similar to this laptop (I'll add them down).Some measurements:

          1- After receiving power SIO_SLP_S0# goes high and never changes.
          2-every...

          dell m6700 no video
          by NicolaM
          hi,
          I have a dell m6700 that does not show video, the display turns on the backlight for about 3 seconds and then turns off, I also tried to connect an external HDMI and VGA monitor but the monitor doesn't even turn on

          I have already tried flashing both bios roms, I removed the discrete nvidia GPU, I changed the ram, I changed the wiring of the LCD panel but nothing seems to change.

          The logic board detects the absence of CPU and RAM, and GPU if I remove them.

          the leds do not indicate any anomaly, the only one that lights up is the caps lock one,iif...
