Reboot Loop
If the console is constantly rebooting it self before displaying anything on screen, there can be multiple things causing this issue.

On a FZ-1 unit:
 * Check to see if capacitor C1 leaked on the board, specifically onto C36. If so:
 * Replace both capacitors.
 * Check the nearby vias to see if they were clogged or damaged by the fluid and clean or bypass the via.
 * Check to see if it leaked onto the power switch and test functionality of the switch itself.
 * Try replacing C401 with a 22uF to 100uF 16v+ capacitor.
