i got both my power/reset and eject light blue, did this when i first had the ps2 about 14 months back, you have to desolder the original led, which is in SMD 0603 package and replae with the new led, for blue either use TG Hyper blue or ISP Blue both of these are the brightest blue available to date, in 0603 size.
i have a lot of experience in mobile phone / cell phone led changing so i knew what i was doing.
one quick question my power button unfortunaltley only lights up blue when on standby, how did you solder yours in
Matrix InfinIty,Romeo Mod + summOne fix ( Added 560ohm resistor on tracking coil, Focus Coil untouched at the minute )
My Advice don't use the resistor fix with v9-10
SCPH-102 mini playstation
unmodded at the moment ( blue led power light replacement )
1.5 Xenium V1
had to remove the resistor as only dvd films would play an they struggled. orginal ps2 both cd an dvd would not load and backup ps2 games would not boot, removed the resistor an all is beautifal again.
