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 ([URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-power-supplies-and-power-supply-design/61916-powersupply-washingmachine-relay-problem?t=67604[/URL])...

by jdbs3With info found on this forum, I was able to repair my Samsung LCD TV Power Cycling, Screeching High Pitched Noise Buzzing and Bad Picture. Instant success - thanks!
The capacitors C102 and C131 were replaced at a local Make It Lab Hacker Night. My thanks to those folks! However, in the process of replacing C131, the capacitor C133 right next to C131 was knocked off. Even without C133 on the circuit board, the TV now works fine. Ditto for laptop, iPhone, DVD and VCR player hookup.
What does C133 do, and how important is it that I now replace it?
Thanks,...-

by sam_sam_samI bought a case of them the battery cells are made in China the charge curve looks decent for 1 amp charging rate there is also a BMS protection board which here is the website link to them
[URL]https://batteryhookup.com/collections/more-featured-products/products/new-full-case-100x-3-3v-2200mah-200x-18650-lifepo4-cells[/URL]

by mich6elHello! Has anyone encountered problems on the Imac 2020 27 inches with a T2 chip? I had to replace 2 T2 chips on two iMacs, the first one was successfully replaced, tested and given to the client. The second iMac after replacing the T2 is flashed, the system is installed through the target mod, it boots into the system, you can hear me tapping on the keyboard, but the image does not display (and to an external monitor). I reballed the T2 chip, changed the processor, RAM, display. No positive result! My friend said that he had 2 such devices and on both of them, after replacing the T2 boards,...Today, 02:05 PM
