If i measure With 2000ohm range it shows single 1
If i switch to 200k ohm range its slowly rising.Leave a comment:

Re: Samsung PS51D550 no picture!
So i measured the resistance between VS and ground again, and on a 2000ohm scale it doesnt show resistance but if i change the range to 200k ohm the resistance keeps rising (Loading caps?)Leave a comment:

Re: Samsung PS51D550 no picture!
Yep im pretty sure that replacment boards are working. How to i check the z sus for shorts? I checked Y-sus with multimeter between VS and ground and i got resistance so the Y sus was shorted(Measured the new board with same technique didnt get resistance). I used the same method with Z sus and didnt get resistance. Should i check something more? And buffer board had one chip shorted to ground. New one doesnt! Did like it in this video to check for shorts [url]https://www.youtube.com/watch?v=51SZsfH60EY[/url]Re: Samsung PS51D550 no picture!

Re: Samsung PS51D550 no picture!
Boards marked with Blue crosses are changed with new working ones.
Ribbon cable with red cross is buffer and y-sustain cable if its connected then VS, VA, VE will drop! If disconnected VS, VA, VE will remain normal.
If you need pictures of every board single i will make them!
And thanks for answering!...Leave a comment:
