    Dell XPS 15 7590 LA-H331P EDP51 no power
    by marcus6100
    Hi,
    my 7590 spontaniously rebooted and showed "workshop mode press ALT-F" in BIOS post, then worked normally for two days, after shutdown a few hours later is dead and doesn't power on.
    After a few hours of measuring I didn't find anything obvious, although the 2.5 Ohm measured might be too low, but I never fixed a notebook before (only other things like TV power supplys)
    Found the boardview cad and schematics in this forum.

    Voltages +1VALW, +3VALWP, +5VALWP, B+, +SDC_IN, +3V_PCH are ok
    +3VS and +5VS is 0 because signal RUN_ON_EC is 0 and UZ1 doesn't...

    Asus X540U No Power On
    by shamaltech
    I have an Asus X540ubr laptop of my customer.
    The problem is it's not powering on.
    When I check,all the voltages are ok.

    I tried heating the motherboard with my soldering iron,after that it started to work fine and also charges the battery.
    After leaving it turn off for 1 or 2 hours,then it's not turning on back again.
    When I heat up the motherboard again,it turns back on again.

    What would be the problem of this?​

    HP 15-da0117nl Lost BIOS info and no TPM
    by DarthMick
    Hi guys,

    i own an HP laptop that suddenly lost all info in the BIOS (serial number, model number, UUID and so on) and the TPM module that used to work is no longer recognized.
    I have Windows 11 installed, but it keeps trying to reinstall the system files without success because the TPM is not present.

    Now i need anyone here to tell me which tools i need to try to reprogram the BIOS and reactivate the TPM module.

    The laptop data are:

    S/N: CND838BGBD

    Samsung UN40H5003 boot loop every ~8 seconds
    by eigma
    Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

    Service manual: [url]https://www.electronica-pt.com/esquema/tv/samsung-esquemas-tv/samsung-un40h5003af-chassis-u8la-71272/[/url]

    SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

    Panasonic TC-P55ST50 8 blinks then no blinks
    by Andre Gilbert
    Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
    Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
