- Prior owner tried a replacement main board. No difference.
- Samsung 2x red blinking standby LED = panel fault
- Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
- Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
- Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

Hello everyone, I have a 645 G9 here with a Ryzen 5 PRO 5675U.
This board has a blown inductor component above the driver chip to the CPU coil, and I am wondering whether the CPU is shorted/dead.
Could anyone please measure the resistance to ground on the leftmost coil/inductor to the CPU?
My resistance value is 2.2 Ohms, which doesn't look good to me.
Thanks to everyone willing to give a value.
