PS2 Green LED remains on, system won't turn on

First thing you do is try reseating the ATX Connector (the 20pin white connector that gives power to the motherboard from power supply)

If this does not fix the issue, then disconnect all the components
(strip the system to MPP i.e. motherboard, psu & proc) and then switch on the pc to check if there is a green light.

If there is then switch off the pc, add a component & restart to check the green light exists.

Do this for the remaining components one by one to check which component is causing the issue.

If there is still orange light then check if the psu fan is moving.

If it does not move at all, replace psu. If if moves a little bit, connect just the dvd drive & check if it ejects.

If it does then replace motherboard. If you are replacing motherboard or psu, replace the front i/o panel assembly (the power switch assembly) for safety reasons.

Its inexpensive.

hope this helps

check if the cpu fan its working fine, maybe is damaged o dirty, you clean up with an air compress can

if still doesnt works you can try to replace the fan and see if it works

is it a slim PS2?
did it shock you when you touched the standby button?
if so, just unplug the power cord from the wall and wait a couple minutes before plugging back in.

hope this helps :p

if not, then you might have to replace the power/eject ribbon cable.
maybe someone more knowledgeable has better suggestions?

Do yo have a volt meter or an atx psu tester?
you can check voltage to see

If a power supply is bad, your pc will turn off or/and turn on and turn off. As long as your system is running without and shut downs your good.

However if your pc is turing off, I would change it as soon as you can. basically what is happening, when you unplug everything there isn't much of a draw on power so the light remains steady, but when you plug devices in there is a draw and the PSU cannot deliver.

I hope this helps.

Hi,
The LED flashes means that the set is in protection, Until unless the problem not removes the protection system keep activate,
First you have to check power supply unit, Check it properly if you have service manual then first check fuse, if fuse is burnt then replace it and if not then proceed check all the capacitors especially main capacitor, check STR also.

The above said components must help and solve the problem,
Thanks for using fixya.

Maybe it has something to do with your power supply, try replacing it with a different one.

Hi Willjan1,

Your motherboard is shot. You need to get another motherboard and install it.

the ps2 connectors are shorted so the mobo out highly recommend replacing mobo

usually, there is a problem with a ribbon cable of power/reset switch. Try using a replacement ribbon of the same type.

buy an xbox i mod them and have absolutely no problems
