The amp has no power. Is there an internal fuse for this unit?
Has anyone taken one apart?

Thanks in advance,
Please please please respect the high voltages that you are working with. Keep one hand in your back pocket while probing or doing anything with a live circuit. Your dim bulb is at high voltage too!
It sounds like it is not doing anything.
Scroll to the first page of this thread (I believe) and see the test aid that I made. Probe and check for those voltages.
Make sure the 2 RTN pins are shorted together. If they are not shorted, short them. (dim bulb in all of the time)
Thanks again gruv2ths for all your help.
EDIT: Never mind, I just found the other hidden screw to the left of the sub woofer analog output. Looking around now....
@gruv2ths: Any ideas on where I should check next?
ALso, what is the voltage across these 2 pins?
Do you have the gray ribbon from the front buttons to the logic board connected? (it connects under the wi/fi card)
The board does appear to be getting power as some of the small resistors around the burned one are getting voltage readings.
@gruv2ths: Could you possibly take a picture of this circuit on your amp and post it here? The reason being is I am assuming the burned resistor values are the same as the other side (750 = 75 ohms) but I want to make sure. Also if you have any advice for me I would much appreciate it as I am bit rusty when it comes to component level troubleshooting.
