note: boardmodel naming seems thus first letter of SKU motherboard (C=COK / D=DYN / K-KTE / M=MSX/MPX) + "SW-001" (with some exception, like the HSW-001 seen above)

Modding

Enabling the "contour leds" in DSW-001 and HSW-001 power eject boards

Power Eject board PS3 2000 series
Detail of the "mysterious leds" at left corner, and unpopulated components

PS3 2000 series (CECH-20xx, CECH-21xx, and CECH-25xx, with power eject boards DSW-001 and HSW-001) has been designed to have a lighted line all around the top edge of the power eject board

This is clearly visible in the plastic "light reactive" material used in the edge, and the square hole in the corner that allows the light to "transpass" the surface (with a 45 degrees angle bouncing surface at top of the hole that aligns the light rays in paralell to the buttons surface)

Under this square there are 2 leds (placed in opposite directions and diferent type, and another 2 missing leds at this side for a total of 4 leds) that are connected to a group of capacitors, resistors, and transistors (most of them not populated) and to the ribbon cable (that goes to syscon)

Why is this subcircuit present in this power eject boards is a mystery, obviously it was designed to be lighted but at some point somebody declined the idea (maybe poor lighting, maybe too scandalous for sony taste, who knows)... the point is the components are missing, so this leds at the corner are disabled from factory

To re-enable them is not only needed to populate the missing components, is also needed to be sure syscon is sending the correct signal to controll them (we have no idea when are supposed to be lighted). The components missing are easy to identificate because are the same than the others present at his side

There is a manual to "bridge" the traces that goes to this "mysterious" leds with the "standby" or "eject" led in this link http://translate.google.com/translate?sl=fr&tl=en&js=n&prev=_t&hl=es&ie=UTF-8&u=http%3A%2F%2Fps3gunz.org%2Fforum%2Fviewtopic.php%3Fpid%3D590435&act=url

• Notes
  • this mod is not recommended, because the "bridged" line is taking too much current from the new leds, because doesnt even explain what is each line, because the leds are not controlled by syscon as originally was designed
  • He didnt taked care of the "bouncing surface" over the square (barelly visible in the photos) and along the curve... all the "light reactive" surface needs to be covered with a "mirror" sticker to make the light rays to "bounce" first in paralell direction to the surface, and then bounce again along the curve. This sticker doesnt exists (because they decided to disable all this), but for sure it was in the initial design to preserve the lighting
