Samsung UN65JS9500 No Power On

[sprocket]

I was given this Samsung 65 inch that was around $5000 new
I found little to none service information it but managed to find the problem
as shown in the image

I had standby and B13 voltages with no fuses blown, so it through me
for a while.

I now have a $2.39 (top of the line) TV and just wanted to pass it on

I have the same TV but when my PS shorted it took out all kinds of stuff including the fuse. Wish I had your luck!... and thanks for info.

>Sprocket. Great find. Glad it was simple. Wish I had your luck with a UN48J5000 I was given. I solved the backlight arcing issue, now facing vertical, colored bars when it lights. My first time to dive into one of these. It HAS been educational and partially successful. Now I'm stuck trying to figure out if it's main or t-con or LCD drivers or panel or some combination therein.

Same model.
Same fault.
Same failed MOSFET.

Part price went up to $2.47 though

Thanks for the heads up.

You check for short circuit, fuse is blown due to over current so you look for shorted out power device.
