Question about Televison & Video
As far as I know there is no service documentation for Atec TV.
I think the one below is your PSU. Detail from this blog.
Check the capacitors indicated with the arrows, ensured they are not bulged or leaky. If any of the capacitors lined with the resistors had blown, then there will be an excessive draw on the resistor, and this will blow the resistors. Eventually replace the caps and test again.
Here the picture in detail.

The most likely cause of this problem is a failed voltage regulator. The excess voltage is most likely causing the resistor to blow. Usually most LCD tvs use a 3 pin voltage regulator IC starting with 74xx Ex:7418
I would recommend that you test the voltage accross it and let me know. If you are not sure what the correct voltage for that IC is let me know the IC no and I will help you out.
