  • 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)

• Notes
  • All LEDs on the board (except the subcircuit with the contour LEDs) are switched on/of from his GND pin (the other pin of the LED's is connected permanently to a volts line). In other words, when the LED is activated the line along the flex cable is connected to GND
  • Contour LED's
    • Are separated from the rest of the board by a transistor, the transistor is activated by a volts signal from PIN1 of the connector, but the motherboard doesnt send this signal, discuss in Talk Page
    • There are several ways to re-enable the contour LED's. And there are solder points without components to duplicate this subcircuit to add another 2 LEDs more for a total of 4. See Modding section

Contour backlight in DSW-001 and HSW-001 boards

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

Light rays bouncing surfaces, and light reactive materials

The plastic plate uses a "light reactive" material along the edge and in a squared hole in the corner allows the light to "transpass" it

The ligth rays "bounces" inside this material, and the first bouncing surface over the squared hole is a plane at 45 degrees angle. This first bounce aligns the light rays in paralell to the board, the next bounces happens all along the curved surface in horizontal

The reflection of this surfaces can be increased a bit with chrome stickers (or alluminium tape). The case has a plane border of 3,5mm x 17,7mm perfect to stick in it, this way the glue layer of the sticker is at the other side, but the case doesnt have the 45 degrees surface (it has a weird hole instead), you can use other colors for the sticker/s because the color is partially visible from outside (preferably lighter colors or one that matches your led/s color to enhance it)

Contour LEDs subcircuit

In HSW-001 board there are 2 leds connected to 2 resistors, 1 zener diode, and 1 transistor (and unpopulated solder points for another similar group of components) all this subcircuit is driven from PIN1 line in the connector

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 the line is cutted in the motherboard, and half of the components are missing so this contour backlight is disabled from factory

The subcircuit is activated by the transistor base pin that goes in-line with the other unpopulated transistor base pin, both does the same function at the same time, each transistor is in chargue of 2 leds with a common zenner diode (the transistor opens/closes the leds ground lines, and when the line is opened the zener diode works as an "voltage regulator" for the subcircuit avoiding "voltage peaks"). These transistors are "isolating" the subcircuit at his left

The unpopulated resistors values are dependant of the leds added

Contour backlight enabled bypassing the transistor

With this method, all the ground pins of the background light LED's are joined together and switched at the same time (4 white LED's from power/eject buttons + the LEDs present in the "contour backlight" subcircuit)

The wire is bridging the connector PIN3 (that switches on/of the backlight for power eject buttons) to the collector pin of the transistor, but also is connected to the collector pin of the other unpopulated transistor, this means all the 4 LEDs of the subcircuit will be activated at the same time by the wire (in the case of adding the 2 missing LEDs with this 2 resistors), and has a common zenner diode to protect the 4 LEDs lines lines from voltage peaks

The transistor function is bypassed by this wire so the area at the left of the transistor/s is not an isolated subcircuit anymore, this can be a problem for the total current of the board and for this reason in the photo there is an "optional" cutted line to disable the white leds for power eject buttons (you are adding 4 leds, so other 4 "needs" to be disabled to ballance the karma)

In the case the transistor is activated (seems not posible because the trace is cutted in motherboard) the collector pin (ground for leds) is connected to the the emitter pin (common ground of the board), this doesnt interferes with the added wire because is doing the same function

The top-left LED (red) ground is connected to this tiny black component in verticall that is a HUGE resistor of 3K Ω, the value of the resistor makes the red light almost not visible, so is a good idea to remove either the resistor or the red LED, is also a good idea to remove one or more LEDs because are different colors (better use one colored LED + 3 whites... or 4 of the same color)

To remove a resistor so tiny with a solder iron there is a trick using a melted drop that connects both pins of the component and when all is melted you move the component laterally. If you approach a solder iron to a LED of this size his plastic cover will "pop up" in 100% of the cases, if you dont plan to recycle the LED this is not a problem, first you destroy/popup the plastic cover of the LED with the solder tip and then you can use the trick of the melted solder drop, the only caution needed is to dont damage other nearly components and use a good solder iron with a 0,5mm tip or so

Other modding manuals related

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
