Can't find video test pin on Samsung PN51F5500AFXZA mainboard BN94-06194A.

I have a Samsung PN51F5500AFXZA with 5 blinking lights. main screen comes on and and then vanishes. I checked voltage.. Replaced Power board and Y Main Board LJ41-10317A. Checked continuity on Ybuffer.
So the only two boards are the main board BN94-06194A and the X MAIN BOARD. When i disconnect xmain. Same blinking issue but no picture.

Trying to do Video test and cannot find anything close to the pins to short on main board. Pics attached. Mine has a cover on part of the main board.

Any help would be appreciated.

It looks like the bottom of the first photo, right hand side, 4 pcb holes marked 1,2,3 & 4

Thanks,

Closeup attached. I was looking for something like bigger pins. I believe i have to short 3,4. Do I use alligator clips?

Use a piece of wire or a paper clip between pins 3 & 4

What issue? I'm still troubleshooting but if it's blinking lights then the general fix is replace capacitors on power board. Lots of videos links for that. I tried that and then replaced board but same problem.
