i bought a 40 dollar LCD (19 inch, i figure not much of a loss if its broken)

and from the knowledge i have of PCs (goin to school for engineering)… the power supply is busted and i suspect its the capacitor.

i have 2 options, build ANOTHER power supply, or fix the current one, anyone with some insight here

NOTE:: i suspect the capacitor because it makes a constant click noise.. it powers up for a second then dies...... then powers up for a second, then dies…

alright.. let me ask a different question.
Anyone know how to ‘judge’ voltage inputs from wire coloring…

black being grounds, reds being 5 volts… anyone know (or have a general idea) what other colors are?

If we take an ATX standard PSU then:
Black = Ground
Red = +5V
Yellow = +12V
Orange = +3.3V
Green = Turn-On (if you want constant power solder it to a black wire)
Brown = 3.3V Sense. (Should be connected to Orange(the small one).
