The board shows 9 MOm
thank you so muchComment

Re: Whirlpool washing machine
how many times did it blow up?
i'm sure the factory didnt socket the psu chip!Comment

Re: Whirlpool washing machine
I don't know how much, and I soldered a socket to make it easier to change later.Comment

Re: Whirlpool washing machine
Looks like something blew inside the socket?Comment

Re: Whirlpool washing machine L2158 control board
blew in the socket and incinerated an inductor so hard it burned the electrolytc next to it!Comment

Re: Whirlpool washing machine L2158 control board
What’s the part number on the IC?Comment

Re: Whirlpool washing machine L2158 control board
The part number is LNK304PN. The socket pin (pin6) that is burnt should not have a connection.
The repair kits have other parts that are likely also bad.Last edited by R_J; 01-08-2022, 07:51 PM.Comment

Re: Whirlpool washing machine L2158 control board
Heh. Frying a ¼W 1MΩ resistor by itself tends to need to exceed voltage rating for dielectric strength as well as thermal limits at the same time...
Then again, if it fails dielectric strength along the outside, then it'd dissipate less power internally...Comment

Re: Whirlpool washing machine L2158 control board
maybe the chip has the same weakness as TOPswitch's and oscillates itself to death if the startup cap is poor.Comment

Re: Whirlpool washing machine L2158 control board
The pin gap from the package MUST be removed from the socket to.
Is removed because of high voltage isolation necessary there and more, with pin removed is easy to not insert the IC wrong.Comment

Re: Whirlpool washing machine L2158 control board
It's not a good idea to socket PWM-FET ICs, because they use the Source/return and Drain leads for keeping the IC cool. In a socket, this won't work and the IC will overheat.Comment

Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
The power supply board reference is the following: DC41-00189a
I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
C57: 3.30V

Patient is a Maytag/Whirlpool/Kenmore clothes dryer. Not sure of exact model, doesn't matter. All boards are out of production.
Specific problem is a Maytag 8544799 / WP8544799 motor-control board, aka Diehl Controls 708879-05. Customer states the board "doesn't work, motor doesn't run". Not sure how the repairman made that assessment, or if it's even accurate. He can't get replacement boards, and the owner decided to buy a new dryer, so whether this board is the problem is speculation on his part. Again, doesn't matter.
I've been over the board looking for...
