SOURCE: Reinstalling Power supply
The green wire with yellow stripe goes to ground anywhere on the chassis. And the black cable should be keyed so that you can only hook it up in one place.
SOURCE: power shuts off and blinks red .
I had a similar problem, but mine didn´t switch on when pressing on button, I had to take the back cover off and hit the relays, it seems they get stuck, and are difficult to find to replace them. Now it has been working during almost a year with no problem at all. Mine is 4 years old.
SOURCE: Fujitsu Plasma Screen won't power up
This is most likely caused by the Main Power pcb.
See Fujitsu Service Bulletin on this problem in a similar model from Fujitsu. -see link below

A competent service technician should be able to implement the service bulletin.
A similar service bulletin is probably available for your model.

SOURCE: SUSPECT DAMAGED CAPACITORS
Bulged capacitors are blown, that is the reason why the motherboard do not start.
Sometimes replacing capacitor may fix the problem, but due to the inexpensiveness of motheboard, and to the chance that more component may had been damaged by the fault, when this happen you usually replace the motherboard, rather then repairing at component level.
