    Magnavox/ Funai 24ME403V/F7

    Picked up 3 Magnavox /Funai sets yesterday. The first I opened had a bad 270uf 200v cap on the primary shorted no other faults. The second and third have the much more common zener/ mosfet failures. This set is less than 6 months old (November 2013) and already someone trashed it. This set has a shorted 36v zener (1n4753a) an open 1.2 ohm resistor and a shorted primary mosfet. My trouble is that the number on the ic doesn't correspond to anything on the web, it is a TK7P500 with a slight possibility of TK7PS00. Does anyone have a cross reference of a compatible part? or an idea of one that might work?

      So I think I have found this part finally. It appears to be TK7P50D, if the standard failure of these power supplies holds true I will need a bunch more components as well. Will update as I get further along with this set.

          Got in my parts order from digikey last night and got this up and running
          Ended up with these defective parts

          1.2 ohm 3 watt resistor
          36v 1 watt zener
          STD9NM50N mosfet was the closest I could find and seems to work fine
          2.5 amp fuse

              VGA MOSfet permanently shorted and loss of MOSfet pad
              by Nooy
              Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

              I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...

              Alienware M18x Shorted CPU Mosfet
              by chestercc
              I've got an old Alienware M18x R1 which shorted out the charger whenever it was connected. Tracked down the short to two shorted caps and burned CPU power controller caused by a shorted mosfet on the CPU's graphic power supply.

              I've replaced the faulty mosfet, two shorted caps and the CPU Power controller (NCP6151S52MNR2G).

              Issue is now whilst there is no short if I attempt to power the system on the fans spin for a couple seconds there are no lights and no further action - the PCH is heating up but there is no CPU power coming out but there is an enable signal...

              iMac 2017 PSU - shorted PFC mosfet
              by mat2k
              I am trying to fix an iMac 2017 PSU, initially came with a blown fuse and shorted PFC MOSFET (6R199P). After visual inspection and some measurements I replaced the FET with a P20NM60 and tested with 100w series lamp, and it lasted 1 second before going into dead short. The PFC controller chip (NCP1605BG) and its passives appear fine (passives measure OK), but I do not know if there is a simple way of testing the NCP1605 as I wouldn't like to blind-replace it.
              There was some slight blackening of the solder on the PFC controller passives so I reflowed them all with some flux. I am waiting...

              MSI GTX-980ti shorted MOSFET on memory rail
              by daemon123
              Hi All,
              I have this MSI GTX-980ti Gaming Golden Edition. It had shorted mosfet on memory. Replaced the shorted i.e. Q47 PK616BA with 4C09N and the card ran fine for a month. Then suddenly again the same problem. This time when i replace it 4C09N or with replacement PK616BA (Aliexpress) it gets shorted. As soon as turn on the PC the PSU shuts down and the same mosfet Q47 gets short.
              What should be the next step. Kindly guide.
              The board view files for this gpu is available and attached. https://www.badcaps.net/forum/showthread.php?p=1237952...

              How do you test MOSFET in laptops ?
              by Jane
              I tried to use this method:

              Testing an N-channel MOSFET:

              Step 1: Discharge the Gate (turn off the MOSFET)
              Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
              Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

              Step 2: Charge the Gate (turn on the MOSFET)
              Now, place the red probe on the Gate (G) and the black probe on the              ...
