    Samsung TV UN75NU7100/Power Board BN44-00874C
    by Larrob19
    [FONT=Calibri]Hello,[/FONT]

    [FONT=Calibri]I have a Samsung power board BN 44–00 874C that is dead. I have looked for a schematic but no such luck. I opened it up and found two Mosfets burnt QP801CS and QP802CS, also the main fuse. I replaced them and checked the two blue capacitors in front of them. They both tested good. I checked the Diode on the same heat sink and the two capacitors in front and they checked out OK. I plugged it in again and that blew the fuse and the Mosfets the second time. I plugging it in again hooked to a 100 W watt light bulb. The light bulb starting started

    PS5 Edm-010 No Power - Help identifying missing capacitor
    by krob80
    Hey everyone. I recently acquired a PS5 that is not turning on (no beep/power). PSU is good and there is no shorting on the 12V rail.
    It came with a Gen3 SSD installed so I feel that things went down hill for the previous owner when it was installed. F7003 was blown but there was nothing shorting to ground. I replaced the fuse but still no power (new fuse is still good for now).
    When connecting it to a bench power supply, it only pulls 10 mA (doesn't spike when first connected).
    I noticed that there are a couple capacitors missing from the Vcore power regulator (pictures attached)....

    SOT23-5 LiFePO4 protection IC? 13D1S?
    by eccerr0r
    I have a SOT23-5 marked

    "13D1 S"

    I wonder if anyone recognizes this IC? It should be a LiFePO4 protection IC, but having problems finding the datasheet, anyone recognize this?

    G00gl3 returns a 6-pin LDO which is not quite right...

    HP 14-CE Series - Blank Screen on Resume - (14-CE360SA) - Motherboard -> G7AL-2G, DAG7ALMB8C0 Rev : C
    by reessi
    Hello!

    This machine had the classic fault that all these motherboards have which is the loose pins on the RAM slot.

    I soldered them as I have done on a few other of these and then it posted.

    Everything works, fully installed with Windows 11 etc.

    Only fault is when it has gone to sleep and you turn on again the screen is blank with no backlight and the caps lock does not work so I assume it has frozen completely.

    Only way to get it to post again is to remove the battery! No amount of forcing off and on will get it to post!

    Satellite r945-p440 - Hard crash coming out of sleep
    by cappernicus
    Toshiba Satellite r945-p440
    Motherboard: FAM2SY2 A3256A
    I do not have a schematic or board file

    I usually let it go to sleep every time I use it because it is nearly always plugged in, with occasional shutdowns to reset things. Then it started to hard crash every time it tried to come out of sleep. The lights would come on for half a second but before anything shows on the screen they would all shut off and it would boot up as if I had shut it down completely (except that windows knows it didn't), and when it comes back on the fan ramps up to full and stays there perpetually...

    MacBook A2141 one USB port dead and one power cycling
    by dbuergi
    Hi all,

    I got a 16inch MacBook Pro showing 5v and 0,3a on the left ports and right side has one power cycling and one showing nothing. The one cycling shows 30c under thermal camera. Surrounding components show no corrosion or any shorts.
    Any ideas what to check next? The whole board looks clean compared to the other A2141s i saw....

    Milwaukee M12-18FC fast battery charger - blown TOP268EG?
    by spleenharvester
    I bought 5 of these chargers as parts/not working from the same seller. Upon receipt all were dead and had blown or missing 3A fuses. Upon connecting to mains I find there is +330VDC across the filter cap and nothing past that point.

    TOP268EG is visibly scorched on all 5 units, with the scorch mark being between drain and source pins. Is this a common fault or have these chargers all been killed simultaneously by a power surge?

    Any ideas what else might be damaged? I am in the process of tracing a schematic for these parts

    Having a hard time dumping BIOS - Lenovo Ideapad Duet 3 (11IAN8)
    by anton brunner
    Hello everyone,

    I'm having a hard time dumping the BIOS of a [B]Lenovo Ideapad Duet 3 (11IAN8)[/B]. The chip is a [B]Winbond W25R256JVEN[/B], directly soldered to the board in a [B]WSON8 package[/B].

    Since there are lots of tiny components near the chip, I was hesitant to desolder it using hot air. Instead, I soldered thin wires directly to the chip's pads and connected them to a [B]CH341A programmer[/B] (photos attached).

    The chip is detected correctly in both [B]NeoProgrammer[/B] and [B]ASProgrammer[/B], but I'm unable to get a consistent dump. I've tried...
