    WAG102 still not working after bad cap replacement

    I've had this A/G wireless access point for a few years now, and ever since I bought it, I've loved it, it has many useful more professional features that the usual home access points didn't have, including vlans (which was actually one of the main reason I had bought it).

    Suddenly it had been acting sporadically, and not really thinking about it and having other things to worry about at the time, I had just rigged up a network cable for my laptop instead of going through wireless. At some later point I had noticed that only the power LED was coming on, and once again, I delayed at actually trying to do anything about it because there were other things going on, note it was powered through Power-over-Ethernet this whole time.

    Well, once I finally got around to it, I popped the case open and looked inside, noticing that it had at least 1 bulging capacitor. I tested all 3 of its caps, verified that at least that one was bad, and went to my trusty electronics supply store and, having replaced caps before on various electronic devices, went ahead and bought all 3 of the correct caps for it (thought I might as well replace them all, seeing as it only had 3)

    After the usual ordeal of removing the old ones and replacing them with the new ones, I plugged it in to test it, and lo and behold, the only LED to light was still the power LED, I get nothing out of the test, LAN or WLAN LEDs at all, no matter what I try.

    Does anybody know what else could be wrong with this? I haven't had a chance to pick up a 3.3v serial to RS232 interface or JTAG interface yet, so I can't tell you what's come out of that at all as of yet, though any help until then would be greatly appreciated.

    See below for a photo of the device (sorry for bad quality, had to use my phone, edited has locations and ratings of each cap, as well as LED, Serial and JTAG locations, MAC address and serial number covered for privacy purposes).

      tried wiring direct this access point to your computer?
      try using a crossover cable for this
      wat is the result, LED lights up? limited or no connectivity?

        Trusty electronics supply stores rarely have low ESR caps.
        .
        If the problem from the bad cap was too much Ripple getting to the IC chips then that might still be the problem.

          Already tried the stock PSU to no avail.

          Also already tried this with no luck.

          I'll look into that and see if that might be the problem, though I do feel like it's a long shot, I've never had a problem with their caps before.

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
            by acedogblast
            This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

            There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

            Unknown transformer : how to find a good replacement part ?
            by the_rem
            Hello guys,

            I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

            I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

            PS4 controller left stick potentiometer replacement issue
            by ezenia
            Hello,

            Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

            So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

            I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

            Macbook pro logic board replacement parts quesion
            by boosti45
            i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...
