Please help ID the Green varistor. I already have the diode part number found on the broken piece (QH08TZ600).

It may be a SCK054 ntc. Measure the original's diameter.Comment

Re: Corsair RM750x help ID blown components
checking this review of the RM750x (2021), mine is (2018) they show NTC Thermistor SCK-037, which seems to be the same diameter (15mm) as the one on mine.

This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets... -
Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.
To begin with, this laptop was dead-dead.
Now with replaced (visibly) blown components, i do get some progress; after connecting battery or main cable;- am getting white power led
- 5-long-flashes on CAPS Lock and NUM lock
- then, fan full speed
- CPU heats up some (smaller die PCH, does not)
- always constant black screen no matter what's tried
- no USB recognition
- no HDMI output
I tried... -
Hi there, i am currently diagnosing my corsair rm750 that wont turn on, after a power trip.
Before the power trip, previously i need to push power button on my pc case quite a bit in order to turn the pc (and power supply on), however after the power trip now i cannot turn the pc on at all and i opened the power supply, and found out some of the component(s) are blown. (picture attached)
My current diagnostic is that the (schottky) diode marked "SF" in the 5Vsb circuit are blown and possibly the ES1DF diode too.
Can anyone help me identify the component... -
Hi everyone,
I have a Chuwi HerBox that has a number of blown components that I am having difficulty identifying. No schematic available.
The fault is that the HDMI port does not really function properly, video looks shaky and has lines. The box boots fine on VGA, so I think the problem is isolated to the HDMI.
The section below is the only section that seems to have damage to three components.
1. Blue Arrow = I think this was a capacitor (as it is connected to ground) that blew clean off the board.
2. White Arrow = I think this is... -
My Sparkle (SPI) PC power supply has broken. Originally, there was totally no power output. The 5V-standby was not there. I have replaced a few bulged capacitors but not helping.
I was trying to do more troubleshooting but burned more components. Some got burned so badly that the markings were gone. And also, the markings of a few transistors were gone because the component surface was worn out somehow.
If you happened to have disassembled the same PSU model, please help to provide the markings of some of these components.
See the attached two pictures of the small...09-18-2024, 08:29 AM
