OK, so done a test
D10/D11 = 550
D8/D9 = 895
D13/D14 = 375 using a EEDM501B multi meter on the 2K ACV settingComment

So, I went ahead an purchased a new main board, turns out it's something further cause it's doing the same thing with a new board in the TV

I have a Haier 50" LE50d3505b television that is "dead." No image, no standby lights, no sound, no nothing. The power supply board is HKL-500201A.
I have tested diodes 10/11 using the "diode setting" on my multi-meter. I got .000 readings for both. For diodes 13/14, I got .177 for both readings.
Do you think diodes 10/11 are the issue and to replace them? If so....would these be the correct diodes to replace them with: https://www.ebay.com/itm/11376729897...QAAOSwDw9bLDvU

Can confirm, D10 or D11. Had to take them both out of circuit to test though.Comment

I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem... -

Hello,
I have a MacBook Air 13 inches 2014.
I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.
I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.
Then I have to find this value in the file : $SVS because it indicate where is the password.
But I can't find the value.
I have attached the file
Thank...
