MacPro does not power on... and does not attempt to boot

Текст:

This machine has not been used much. It was purchased in 2011, and has been idle for about a year.
 
# No light appears at the front where I push the start / on button
# No internal sounds are evident
# I replaced the BR2032 with a CR2032 and no different outcome when I push on button
# Not much dust inside
# I removed the graphics card and re-seated. Did the same with CLU shelf and disks.
# A red light flashes, if I attempt to plug in while CPU shelf is out, so there is power to the mother board
 
It was working fine when I shut it down a year ago.
 
Any ideas?
 
Thanks, John

Hi Jim,
 
The pics are a bit dull. This pic should show that memory slots 1-4 have 1GB stick, slot 5 has 4 GB and slots 7-8 have 1 GB sticks.
 
I believe that this is way it came. Above, I indicated that my son my have borrowed some memory but I was wrong.
 
:-)
 
Thanks for your interest,
 
Max

Still funky... The point with pics is that there is virtually no dust.

Ok this may work... meaning that these images may upload from an iPad. The images are a bit dark. I can get a better photograph if that is useful.
 
I could not upload to the 'comment' edit box.

Hi Steve,
 
I am glad you asked and that iFixit provides a facility to reply.

Machine:
 
Mac Pro - Mid-2010
 
Symptom:
 
If I let the machine sit unplugged for a week. It would then start, but would automatically shut down after several hours and never re-start... until say, another week had elapsed.
 
--
 
I am technical from a software perspective and I think I can fix anything... however, I failed personally and then took the time to find someone who would not just swap the logic/mother-board and call it fixed. Finding someone was not easy. I live in Canada, and this will sound harsh but all Apple certified places that I took the machine to were providing swap and replace services. I did not not want to do this for several reasons. They quoted the cost of a thousand for the logic board from Apple, then their labour.
 
I have two (2) identical machines. One was never used and the other is used regularly. The never used machine was the one that failed. Once, I decided I was going to fix it, I swapped all the components between the two machines and found that it was not the components. Then I took the logic board/ mother-board out and cleaned it with electro solvents, because sometimes the machine would work for say a day, then fail to start... for forever. I suspected that the problem was either capacitor or power. Cleaning did not resolve the problem.
 
I finally found a company that would do on-board repairs. They will charge $400 to replace the power chip.... and guarantee their work for three (3) months. I will get it back next week. I will post here to confirm that it is fixed.
 
--
 
Normally, I use high quality surge protectors but I am thinking that this machine may have been plugged directly into the house power system... we have electrical storms here, hence the power chip failure. I am guessing.
