    Coolmax CX400B GI

    Just thought I would post some pics if the caps in a CoolMax 400w PSU. They are GI brand which I have never heard of. This Particular PSU just stopped powering up one day no particular reason. Less than 6 months old.

    Pics aren't that great. They are taken with my LG EnV Touch cell phone.

      Sunpro/leadman. Typical crap.

          Looks a bit better made than this sun pro.

          I love putting bad caps and flat batteries in fire and watching them explode!!

          No wonder it doesn't work! You installed the jumper wires backwards

              Looks the same as my 2 broken coolmax cu-500b. I replaced every single cap and mov and it still blows fuses. I havent bothered to troubleshoot beyond that.

                  if it's blowing a fuse then it wasnt the caps, more likely the rectifier or primary transistors.

                      I really just posted this for information. I'm not going to attempt to repair it, since it isn't worth the time invested. I think it was purchased for about $25.00.

                      I have to convince the boss that cheap PSU's don't save us money.

                          Here's more proof. The first and second to last units are from the same manufacturer of this coolmax. (leadman/sunpro)

                          The first one on the second page is the brand you should use most often.

                              Help with trying to fix phone that is not charging (Pics inside)
                              by SluggerB
                              I have two TCL A30 phones.

                              Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

                              New Phone: Works fine, bought as a donor board to try and repair Old Phone

                              My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

                              new OS on a Sonim XP5s phone
                              by keeney123
                              To you programmers out there I want to know if it is possible to put a new OS on the Sonim XP5s phone? I only need this phone to make calls, receive calls, have a list of contacts and be able to call voice mail.
                              I bought this phone new Sep.2021 as an unlock phone from a third-party seller. The phone worked fine until Jan 2022. I then had intermittent problems with the sound setting resetting itself. One of the settings, outdoor, would go to silent all by itself. When in silent mode it does not indicate a call has come in. I missed very important phone calls. All the other setting in sound...

                              Hi all,
                              Got this smart phone free from a guy who dropped it hard until the lcd display cracked with no seen display.
                              Opened it and found the display ribbon cable partly damaged. I charged the phone full in 2 hours time, the led red light turns to green indicate full charge.
                              Then i use a usb cable connect the phone to laptop but it only showed as media player with firmware version. Too bad there is no option to check folder.

                              Does anyone know any method to check if the phone is working good? Looking forward for any advice and help possible.
                              If tested the...

                              Cisco IP phone F-up
                              by Dannyx
                              Good day folks. I had a little f-up over at my new shop today and it made me pretty angry, but at the same time it determined me to try and figure out what could've happened there. This is only going to be a speculative discussion since I don't know the exact layout of our network, hence I don't know what's going on past our room. So:

                              The repair shop where I sit is situated in a remote building down the street from the main building. There's a Cisco IP phone in this room, a 7911, like the rest of the company uses. There's obviously some sort of networking going on between the two...
