Doesn't charge and doesn't turn on

Hi guys I have this Mac that I have tried about everything.

Tested some of the components on the logic board. I can see some voltages, to be honest I dont really know wht component gives what voltage.

Would you have any tip about dead logic boards?

Any known component to be replaced, any ideas?

MagSafe doesn't even show any light. I tried different MagSafe as well as another battery.

Is this a good question?

Lets backup here a bit. What happened to the system. Did you bang it or get it wet? If you press the built-in battery checker does any of the LED's light up? Looking at the AC adapter what is the wattage of the unit sadly its in light grey ink so hard to see or even read. Are the two AC adapters the same?

Sounds like this system needs quite a bit of work here.

As the battery tester doesn't work we know the battery will need to be replaced. We also know the MagSafe power logic is damaged as the AC adapter LED is not lighting we also know the main logic board is also in need of repair as well. You may also have to replace the keyboard and/or the trackpad.

At this point I'm not sure this worth all of the labor and parts to fix.

Sorry for the bad news ;-{
