    A1707 820-0098 5V power loop all USB-C except one jack, and strangeness after replacing the one bad CD3215C.
    by abajor
    I have this 1707 with the 5V 0A power loop issue on 3 of the jacks.
    One of the CD3215C00 had corrosion under one side U3100 to be precise.
    This USB jack was drawing ~.2A and not boot looping.

    After replacing the CD3215 I am having an odd problem. I can rotate the USB-C and it only works in one orientation. And now it boot cycles, like the other usb channels so I'm part way there.

    After looking at the schematic and board view. It makes very little sense that this is happening since they both pin 59 and pin 60 both go to the same places on J3300.

    APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
    by sam_sam_sam
    This started a few days ago and does this about every 8 hours

    After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

    The battery backup is about 3 or 4 years old

    Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

    Sony XBR-52LX900 BL_ERR
    by Nicktronic
    Hi all, just curious if the BL_ERR signal is active high or low? TV has the 6 blink error code and I've changed the backlights as they tested questionable (4 strips tested - 203VDC, 203VDC, 203VDC and 175VDC). The new strips all tested at 175VDC. Now when I turn it on, it tries twice to come up and then the 6 blink code. During the this time the BL_ERR pin is high and drops low momentarily, then does it again on the 2nd try to boot (so Im assuming active low). The other thing is the backlight voltage ramps to ~280VDC from around ~160VDC and then back down as the TV tries to boot again. Does...

    >>> Troubleshooting Delta Power MAX 500ATX ATX power supply
    by dragon3x
    Hi, this is for troubleshooting and, hopefully, repairing a Delta Power psu
    that is still quite new, as it worked OK for some months until it failed.
    At the time I was not into power supply electronics; it was put
    aside and a new power supply installed inside the computer. Also at the time
    power supplies were half the price of today's.

    On the PCB there are a D339 and 7500B chips.

    I have found that schematics with these 2 chips (see included file).
    Does it represent the actual circuit of the MAX-500ATX, I cannot tell.

    Some measurements,...

    Troubleshooting Razer Blade 15 DA560
    by chickenhawk88
    I started troubleshooting this Razer Blade 15 laptop DA560 motgerboard a while back, due to some shorted 19v, 5v, 1v power rails. I fixed some of components and think 19v rail is good, 5v rail is good, 3v is better but not all way i think, and 1v is still bad. At this point the diode reading on these rails are 19v - 0.032v , 5v - 0.167v, 3 - 0.63v and 1v - 0.005v .

    When the rails when down, I went down different rabbit holes and seeing chips getting pretty warm on thermal but not blazing hot. Yet there were not any caps or any small components getting blazing hot. Example is EC chip,...

    Hisense 58R6E3 Backlight/No Picture Repaired
    by petersor
    Quick repair summary for those interested. I had a Hisense 58R6E3 TV that had backlights working but no picture. T-Con had 12V supply but some of the supplies on the board were 0V. Unplugging one of flat cables to the LCD display driver boards brought the supplies back up, so I figured it was a short on the LCD panel driver board. Narrowed the short down to the 15V power supply by checking the coils on the T-Con board to ground with a diode test and confirmed that all the MLCC caps on that rail all showed a short to ground. I injected 5V/1A into the 15V rail on the driver board (T-Con disconnected)...

    Xbox 360 Xenon Modern Capacitor Replacements
    by burom
    I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.

    I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have...
