    Please help Asus ROG G713QY-K4005T (SN: MANRKD03332840C), motherboard ref: G713-6050A3254002-MB-A01 (A1) Bios
    by eastcoastcomputing
    Hi there,
    I have an Asus G713QY that won't boot. The machine fire up to a black screen, no post but everything seems to check out on the board. I believe the motherboard needs the bios reloaded but I can't find the bios file. I've looked on the [URL="https://rog.asus.com/laptops/rog-strix/2021-rog-strix-g17-advantage-edition-series/helpdesk_bios/"]Asus website[/URL] but what is available for download is the .exe to run in windows (which won't help). I've tried to unzip it but can't see the bios file that I need. Can anyone share the bios file for an Asus ROG G713QY-K4005T (SN:...

    Allview phone charger A248-NB2-501000
    by DanPoka
    I've got an old phone charger which cannot hold voltage, it goes from 5V to 4V the fault only seems to happen when charger has been on for a while e.g. when warm. Fault happens when high current or low current is being drawn from charger. I've checked capacitors for capacity and ESR and I think they are still good, I've even replaced a cap to get better ESR. Fault still happens it goes slowly from 5V to 4V then interrupts power and restarts. Because it performs on high current (0.67A) and low current (20 mA) the same way I'm guessing it's not the caps but more likely the switching IC. However...

    Samsung UN50KU6300F constant reboot, bad backlights?
    by x_orange90_x
    This TV is in a constant reboot where the screen very dimly lights up for about 2 seconds and says SMART TV. I checked the power supply and visually all components look good. I unplugged the main board to see if the backlights would come on but they do not. I also tried my LED tester on the backlight plug and didn't get anything. I know some Samsungs will not light off a single led is out regardless of using a tester, so I'm thinking they are bad. I found a whole set for about $25 which isn't bad, but before I buy them is like to know if they would indeed cause a constant reboot like this tv is...

    Xiaomi Mi 15 Pro - R15-6050A2940901 Schematic
    by gurj1979
    A while ago I got hold of a Schematics but was full of Chinese watermarks with embedded links and crap.
    Also Page 6 was mangled with overlapping diagrams of the charging circuit from Page 5.
    Same messy version going around the internet on multiple sites.

    I've brushed, cleaned and polished this up, and publishing it here.
    Perhaps I'm the only one who's done this.

    I'm sure you'll all appreciate this cleaned up version....

    The last AM4 upgrade
    by BigTroll
    Back in 2017 for the launch of Ryzen I bought an Asrock x370 Killer SLI/AC and Ryzen 1700 motherboard combo from newegg, it was a good deal but I didn't think it would last me so long. I originally had 16gb ram a EVGA GTX 970 latter the 970 was replaced with a EVGA GTX 1080 and finally a Nvidia Geforce 3080 Founders Edition. the CPU went from a 1700 to 2700x, 3900x and now finally to a 5950x and I got 32gb ram. I still cant believe how long AM4 lasted and the 5950x was $348 with tax included from antonline using the 20% presidents day coupon. I got a ID cooling 360 water cooler on her and shes...

    State: when power button pressed white power button led lights up for 10sec the off for 8sec and then back on for 10 and that is happening in the loop. When charger connected charging light is on battery is charging. Checked with mmeeter. Done some basic fault finding but no luck. I've reprogrammed bios. No good. I want to start from scratch. Please guide me what to measure first cause I'm lost now. Thanks.

    Apple MacBook Pro 13 2020 Intel silicone 820-01949-A A2251 no sound
    by koinoyokan
    Hi guys, I hope you can help me. I'm trying to identify an audio chip on this device, since NVRAM reset, SMC reset and replacing speakers yield no results, I'm pretty sure it's the chip. The sound comes back briefly after [I]sudo killall coreaudiod [/I]but it's muffled, as if the speakers are blown, which they are not. Same effect with SMC reset -- the sound comes back briefly, sometimes the chime can be heard, sometimes it's absent.

    I have a schematic for the Open Board View, but I can't seem to locate what is usually an audio - U6200 or U6201, what am I doing wrong?Hi guys, I hope

    Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
    by odie34
    I am a hobbyist (not a professional) so please be gentle...

    I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

    I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...

    by riparo
    Hi everyone, I have a Panasonic OLED TV model 55EZ950E, as soon as I turn it on I don't have any image the LED goes from green to red LED blinking every 4 sec, I found the service manual suggests checking OLED PANEL, PB BOARD, T-CON connectors but it seems like everything ok, I didn't find any burns under the pb board
    I attach a link to download the service manual, thank you for anyone who can help me
