    Re: Select-able wall wart power supply - dead

    So for anyone rise in the future reading this thread, is there a faster way that I could have found this out sooner? I don't mind, I was taking it apart for fun. but for a problem like this, What is the process of diagnosing the failed parts on one of these?

        Check the primary winding for open circuits, and if it has primary fuse, check that too.

            Yes, and also overloading can cause it to burn out. Also, poorly designed transformers might burn out earlier too.

                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.

                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?

                Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                by sam_sam_sam
                I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                Samsung QE 75 Q 7 FGMTZG Power Supply dead
                by kevin_allein
                Hi, have this Samsung QE 75 Q 7 FGMTZG TV with no function. First analysis shows the power supply board is dead and fuse blown. Power Supply has the number BN94-11439A. I did short circuit test transistor and diodes and those do not appear to have shorts. I must admit I did not look at every single data sheet.
                In the TV was some black dust residue, so probably one of the electrolytic caps blew, but they do not show short either.

                Does anyone have schematics for that board ?
                Any good tip, what could be the issue ?

                Eufy Floodlight Cam 2 Pro Dead. Power Supply issue...
                by KYBOSH
                I have a floodlight-security camera that recently died on me.



                its hardwired to 115v po115v outlet. One evening it simply died. After some troubleshooting (ensuring it had power and ensuring the electronics were actually functional by supplying 5v via usb port) i realized the power supply must be the issue. The supply was noticably warm to the touch even though it was not powering anything.

                Trying to understand what i was up against i went looking for others with similar issues and anyone who might have attempted a repair. While a few ppl have had the...
