View Sonic n4060w (VS10846-1M) NO POWER

[ryanfan03]

I picked this tv up the other day and just now got to it. I plug in the TV and there is no standby light and there is no response from the buttons. I immediately think of the power supply. After reading some things I check the fuse and then the voltages.

Fuse is good

V across big cap - 357-359v

CNS1:
Pin 1 - 0.3v
Pin 2-12 - 0v

CNS2:
Pin 1-9 - 0V
Pin 10 - 5v
Pin 11 - 5v
Pin 12 - 0v
Pin 13 - 0.3v

I then recapped the entire secondary side. No change to the readings. Am I wrong thinking it is the power supply and maybe it is voltage regulators or something from the main board. Also this board does not have a connector on CNS3.

I have (I think) attached pics of the power supply.

Is there any indication of what the various pins are, ie is there any markings alongside the connectors.
It looks like you only have 5V standby voltage at the moment.

No indication for the connectors

Bud. I saw that thread. I will try some of those things. But mine does not have any indicator light when plugged in. Also that has a connection at CNS3. So i dont know if mine will be like that one or not.

When i measured the big cap it was with it plugged in and no buttons pushed. I will recheck to see if any of the values change when i hit the power button.

ive worked on one of these sets try heating the power supply up for a few minutes with a hair dryer see if the set works then im sure mine was a small capacitor on the primary side giving me problem

Did you look at the PDF of my post 15? It shows the pinout of CNS1~3.
Your reading of the CNS2 cannot not be right in post 1.
CNS1, CNS2 has the same pinout.
We need the DCV reading of CNS3.

I will have to check that out. I listed Pin 1 as the one on the left. Also I have nothing at CNS3.

EDIT - I am a little slow...I do not have a connection at CNS2. My readings above are for CNS3. Sorry
