    How to check PFC IC UCC 28063 for possible short

    Need help. Samsung 75" TV has an issue with the power supply board. I found a shorted mosfet & blown fuse. I replaced both but the mosfet blew up. I suspect that the PFC driver IC is bad but not sure how to go about checking it with a MM.

      DELL Nvidia GTX 750Ti Mosfet goes short after a few minutes
      by aaronkatrini
      Hi all,

      I have recently picked up this Dell OEM Nvidia GTX 750Ti 2GB Video card. Its an old card I know but still wanted to get it working if possible. The problem is the following:

      - Put the card in my testing motherboard and start running Heaven benchmark
      - Benchmarks seems to run smoothly up until half way then the motherboard completely shuts off immediately
      - Try to start it again and I get a slight move from the PSU fan - a clear short
      - A little troubleshooting later I find one shorted Mosfet - Replace them both - short is gone
      - Put the...

      Acer AN515-55-528T FH52M LA-J891P - Short ciruit after PQW1 MOSFET on +1.35VSDGPU rail.
      by joshAU
      Hi all.
      This notebook was showing no signs of life.

      I removed the FH52M LA-J891P mainboard and found that there was 19V at the DC jack.
      However there was zero volts on the two PRB2 and PRB46 resistors immediately after the two polarity protection MOSFETs (PQB11 & PQB12).

      If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.

      I tried replacing the MOSFET with a new one, but again no voltage on the...

      Acer: No power after first MOSFET no short? Looking for guidance.
      by vexarvf1s
      Looking for guidance in tracking down missing main power rail.
      I have an Acer that I am working on. It runs on the battery, but does not charge. I changed the power adapter and same thing battey not charging, and continues to discharge. So I opened the computer and started looking for the problem to fix.
      First thing I checked is if the power form the charger is getting to the mainboard. I found that 19V is going all the way to the first MOSFET. So DC jack is fine. However I do not have power past the first MOSFET.
      So checked for voltage on the gate of the first MOSFET and...

      Extreme High Current & Low Voltage Short Killer ??
      by DynaxSC
      Hi Folks

      I'm looking for a extreme high current short killer solution for a reasonable cost.

      I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
      After taking off the socket, the shorts dissappear again.
      The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

      ASUS TUF FA506IV-AS76 vram mosfet short, then battery cant charge
      by jkyoho
      I recently fixed a FA506IV cam with Vram mosfet short on Vin(19vοΌ‰to ground. Got both mosfet replaced and now laptop could turns on and GPU everything works but battery not charging. Battery status shows 100% on both BIOS page and Windows system.
      Measured voltage got 0.3v on battery red lead not going up. charging mosfet gate low and 19v not passing through inductor.
      I also tried dc bench supply 14v charge directly onto battery but seems not drawing anthing.

      Any idea?
