Step for the realization of a screen from an iMac G5 17 "/ 20 • Preamble:

This step aims at the realization of a DVI monitor from an iMac defective

allow a second youth in our poor iMac, DVI

is a connector that is not compatible with VGA, I

'm not responsible for damage incurred after this step.• Materials needed:

-1 IMac 17 "defective.

-1 DVI cable, insulation 2mm/4mm, ribbon, welded iron, son, various

connectors, switch inverter, various screwdriver, magnifying glass that

• What we do: retrieve the slab, connected on the DVI cable, recover

The food, get the chassis of the iMac.

5 GRD

11 5V run

6 3.3 V all

12 3.3 V run

• the power connector

• Voltage available visible on the back of the card logic

Device is switched on the screen:

• For the supply of organs of the screen using a connector that clips on therecord (j I get a socket on a standby card mac) is the wires and we cut it

uses a chandelier or other connection, although spot.



The inverter that is on the right side of

the slab, do not remove

• To start the inverter it takes about 3.3 V Run Over No. 2 brown is connected to the12V Run

and the wire 3 is connected to the GRD wire # 1 (not connected) and adjusts the

brightness is at 0V.

The inverter will be supplied only

when we will start the PSU

Connecting the signal cable of the slab (DVI) • To do this we need the datasheet of the DVI

• And the datasheet of the slab for the 17 "Phillips

Links between the two cables

• This connector located at the rear of the slab, must be disassembled to identify son



• Strip the other end, there is attention from very fine wire and the wire

tanks, stripping son with nails for example does not pull the strands of

copper.

• Allow the heat slug 2mm, the wire noted the tape, a soldering iron.

There must be a DVI cable 1.5M

Strip one end there is attention from very fine son and the son shielded.• This is the trickiest part, it is about connecting the cable to the DVI cable is

connected to the

slab containing the datassent of each connector.

1 - note pad all the cable datasheet on each wire screen of 1 to 24 by 17 "

2 - note all the DVI cable DVI datasheet on each wire from 1 to 24

3 - twisted pairs of TMDS son + / - the shortest in order to avoid noise.



4 - connect together the two brothers son cable, except that another mass GRD

fils19-20-21 which is the mass of the diet.

although the polarity rx + / -, I didn t connect the shield (ground)!

Do not connect 5V + and hotplug nor the son is (the single)

isolated welds with heat slug

5 - 3.3 V will be connected to 3.3 V power supply All of the GRD and the GRD alim6 - isolated at the ribbon

Last

in

instead of cables • Colson cables neatly and locate the position of the connector when the slab

it is in place and mark on the iMac.

Me d I spent the DVI cable into the hole in the ethernet! bof, if not to drill

center ;-))

I test on a slab

separate power supply,

with the DVI cable

connected to the slab andPWM

The slab is tested

The brightness is

good, I can

mounted in the iMac



good luck
