Sony KDL-46NX700 Led does not stay on

[PowerAmpFreak]

Hi all.
This Sony led-tv model 46NX700 does not stay on more than 30 seconds at a time. It shows a good picture and sound during this period.
Then exactly after 30 seconds it shuts down and re-starts.
Front led does not flash either.
Mostly working on Samsung's, would need help with this dude.

I have repaired a similar one, the 720 model and it was the LED driver board(one driver IC).
There are some test points on that board, you can see if there are any differences between them.
Mine, didn't reboot if I remember correctly.

Do you mean the PSU board, containing the LED driver?
See attached...

It looks like your power supply board also contains LED driver circuits.
