    Acer nitro 5 N20C2 No charge
    by madjid911
    hello I have an acer nitro 5 model N20C2 (motherboard FH51M LA-J871P rev 1B) which does not charge, it turns on perfectly but when I plug in the battery, we see the charging indicator and the charged battery logo but it turns off a few seconds later, and there is no way to turn it back on, you must then disconnect the battery and the charger. If I turn it on without the battery it works fine.

    I changed BQ24781 but the result is the same, I put after BQ24800 the same, I then checked all the resistors and mosfets, everything is ok, I bought a new new battery but the result is the same...

    Help me find the short circuit on this WORKING Nvidia GTX1650
    by aaronkatrini
    Hi all,

    Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

    Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

    Samsung UN70TU6980FXZA no sound no picture but does have backlights
    by stinger
    When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?

    Biomass Boiler not driving cleaner motor relay. ENERTRES BIOMASA BI-650
    by edugimeno
    Hi everyone!
    I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
    I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
    This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
    To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
    I respected the polarity, positive to cathode of protecting diode
    So provided all...

    Luxman R-5045 - Voltage too high accordingly to schematic
    by mikkele86
    Hello.

    got this Luxman R-5045 vintage amplifier which need a good repair and service.
    finally got i started up and started to check voltages.

    My issues is that the voltage measured is 3,5v to 4v higher than whats stated in the schematic.
    Meaning voltages like +9v is like +13v
    and +31v is measured to 34.6v which is really close to the capacitors rating +35v

    I measured the voltage before the rectifier and im measuring 27v
    did a online calculator and it showed i should actually get +36v after the recifier :/

    So my question...

    Hi All,
    Laptop: ASUS F15 TUF Dash FX517ZC-HN114W

    Context: When I was out the house my partner hard shutdown laptop while BIOS was updating, so my son has no working laptop now. Also as a result I know the BIOS on the chip is messed up so I can’t extract it using the ch341a and use it to perform the method explained on site to modify an update downloaded from the ASUS website to get the BIN to flash.

    If anyone can help with a BIOS BIN/ROM file for this laptop, I would be forever in your debt! Thanks if you can help!

    LG 43LH510V Backlight problem
    by unimatrix93
    Hello everyone,

    I'm trying to fix a small LG TV with wierd issue.

    So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
    Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
    The BL turns on, the tester shows around 80V. So the led strips are okay it seems.

    Now I started to suspect the BL driver IC which is a MP3378.
    I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.
