Hi,
This kind of symptoms indicated that the power supply was disable. The most common caused of this fault is the dried filter electrolytic capacitor in the output of this section. It will dropped the normal working voltage of the power supply feeding the mainboard and other boards. To isolate the faulty one, you must have a capacitor checker to determine its condition. Another caused of this symptom is the dried/cold solder in that board also. This is hard to spot, you must work in the brightest area or used table/portable lamp and magnifying glass. Re-solder the power supply board as much as possible.
Faulty power switch is also to consider here. You may spray it with the contact cleaner to clean the contact from dirt.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
