    TrendNet TEG-S80g Bad Power Supply

    Hello,
    I was wondering if anyone out there has worked on TEG-S80g Gigabit 8-port Ethernet switch. The switch stopped working, no light or activity. Upon opening it up, it was no surprise that a regulator chip was blown. I'm trying to identify that chip, or find a replacement for it.

    Chip is U1 as you can see from photo. It's marked with EGAx and I can't read that last letter.

    Anyone know what that is? HW revision is V2.1R
    Thank you

      Maybe this Richtek? http://www.s-manuals.com/smd/eg

      Something else may be bad too if it blew.

          The regulator in the TEG-S80g switch is a GMT G5626 which is an obsolete part. The replacement is a G5692P11U which has a higher input voltage spec of 6 volts max. It is available from a few ebay sellers.
          IC will blow if you connect a 12 volt supply!

              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.

              Assuming...

              Ubiquiti Unifi PoE Switch US-8-150W Power Supply Failure
              by shovenose
              Got this one for free because, well, it no worky.

              A little research and there are tons of complaints all over forums/the internet about premature failure of these switches. The observation everyone makes about these is "they run hot" and failure occurring as soon as 13 months, right out of warranty, of course.

              Upon removal of the cover I found a G0398-15011480A power supply that, when plugged in, was making a constant ticking noise. Multimeter confirmed the PSU was the issue. Output was cycling between 0 and about 20V. With output disconnected it sat around...

              Russound CA4 Power Supply Repair
              by CMCM
              Hello Everybody,

              Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

              Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

              The outputs marked 12v and 20v are all measuring only 1v.

              The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

              The capacitors physically look clean (no bludgesor leaks) and...

              Mid 2014 A1398 MacBookPro,Is it feasible to remove the battery from the MBP and connect it to an external power supply?
              by Gust zhang
              ​I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...

              Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required
              by Andreas_de
              Hello!

              i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
              Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

              Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?
