    How can I be sure that my EC chip is dead?
    by double_DD
    Hi all,

    As the title suggests, how can I be sure that my EC chip is really dead?

    I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

    Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

    Gaming laptop Clevo NH79EP with short on 5VS-rail
    by techrepairheide
    Hello,

    first of all I want to apologize for my bad English, but I try to give my best.

    Customer brought me a laptop, which is charging the battery (when the dc-jack is connected) but don't power up when the power-button was pressed down. Only the white LED lights up, and you can hear a short noise in same interval when power-button was pressed and hold for longer timer. The customer changed already battery and dc-power-adapter.

    For this laptop the correct shematic is the service manual "Clevo NH50ER NH57ER NH50EPS NH57EPS - 6-71-NH5S0-D02 Schematic"....

    LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
    by ygorsan
    Hi everyone,




    I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







    🧩 Problem Summary:
    • The TV keeps scrolling through the menu or selecting items by itself.
    • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
    • The remote control is not in use (batteries removed), and the TV still shows the same behavior.

    HP Victus 15-fb dag3pamb8d0 Short on VCORE – How to Confirm CPU Fault?
    by adelfr2009
    I have a laptop HP Victus 15-fb with motherboard DAG3PRMB8D0, CPU Ryzen 7535HS, and GPU RTX 2050. The laptop has a power issue: it does not turn on at all, and there is no light on the DC jack.
    After inspection, I found that an NMOS near the charger input had a short. I replaced it, but the short remained on the 19V line. I checked the charging circuit and it was fine, but the short appears after the current sense resistor near the charger. The charger does not pass current when connected, so I inject 3V–4V after the sense resistor. No component gets hot, except the CPU which becomes...

    How can I test coil whether it is really broken or not?
    by chth96
    I have old game console which have connected to 220v outlet by previous owner and It is not able to turn on.

    I checked continuity of fuse in PSU unit with a multimeter which is shown in the below picture with a orange circle around it, and It seems that fuse became open circuit.

    I also found that as well as bulging capacitor, there is unidentified coil which has residue all over its surface
