Re: Samsung PN51D450A2D - 10 vdc on VS 3vdc on VA
My x feeds the power from the ysus .
When x is disconnected from y I have 10vdc coming from the power supply on the vs wire.
Is that what you meant. ?
I could only find another spot on the board that had vsc. But there was no voltage .

Re: Samsung PN51D450A2D - 10 vdc on VS 3vdc on VA
So I realized that I did this wrong. I was omming and testing for continuity.
Now that I put the meter into diode mode, I believe I have two blown transistors on the y main.
Can someone confirm this for me, these are my readings.
From Left to right in image 1
Left to center – 1.5
Center to right – 5.9
Transistor 2 – ( has combined left and center leg)
Center/left to right - 4.21
Transistor 3 -
left to center – .OL

Sorry about that, I have done a lot of researching, but have not found anything with the same issues. Some have similar problems, yet they get correct voltages on VS and VA, and the similarities end there.
So full disclosure here….
With everything connected, upon power up I get the samsung tune – followed by a few clicks and then nothing. Logic board led reads 5 sec on 2 sec off.
Disconnecting the ymain from the powersupply board yields the same result.

Re: Samsung PN51D450A2D - 10 vdc on VS 3vdc on VA
Just an update to this as i havent gotten any replies.
I replaced the main input board as well as the logic board and still have the same result.
When i meter the VS-0n i get 1V
Same readings as before on the VS and VA Test points on the power supply board.
Can anyone help point me in the right direction or offer some advice.
ThanksLeave a comment:

Samsung PN51D450A2D - 10 vdc on VS 3vdc on VA
Hey guys ,
Long story short tv was working, came back in the room it was completely dead. No power at all.
Replaced the power supply board.
Now it plays they Samsung tune when I plug it in but no change in the screen whatsoever.
When I use my multimeter on the vs testpoint I get 10vdc.
On the va test point I get 3vdc .
I've tried the process of removing the other boards from the power supply and rebooting but same result .
The logic board is blinking 5,2
Please offer any assistance on how to... -
