    Original Xbox Power Supply Repair - FTPS-0002

    Hey there friends!

    I have an original Xbox power supply, model FTPS-0002, that isn't showing any signs of life. I have never really done power supply repairs before but I'm eager to learn so I am hoping someone can help me diagnose this.

    The issue is that I get no 3.3VSR standby voltage which in turn leads to no 5v or 12v. A couple things I have noticed in my initial inspection.
    Resistor 25 and 29 are both reading OL, Capacitor 17 and 20 seem to be leaking as seen in the photos.

    So far I have confirmed that 240v, main fuse and the 400v cap is functioning correctly. Then I am completely lost after that.
    My only hunch at the moment is to replace the leaking caps to see if I get any different readings, not sure if that would cause issues with the resistors though?

    Thanks everyone!

      change all the electrolytics for panasonic FR series - that especially goes for any 1200uf caps that foxlink liked to use.

      cant help with the resistors right now - i dont have any open.

          Thanks heaps for the input. What would you recommend to remove the glue?

              i use a combination of tweezers to pull small bits, longnose pliers on big bits and a small flat screwdriver for lifting/scraping

                  I have the same PSU and need a list of the resistors on it, the color bands on mine are all unreadable.

                      so that psu is universal voltage?
                      or you have a 110v version?

                          you have possible cracked solder joints.

                          resistors are clear in your photo's - they probably work

                          R25 = 1k
                          R29 = 1k or 3k, hard to tell if it's brown or orange at the end

                              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.

                              Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
                              by JimBanville
                              The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
                              Opened it up and discovered the power supply is making a faint clicking or ticking sound.
                              I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
                              I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

                              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...

                              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?

                              Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
                              by shamsudeen
                              Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
                              I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

                              i know that in linear power supply the noise will be very low comparing to SMPS supply....
