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.

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

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 ;-))

with the DVI cable
connected to the slab andPWM
The slab is tested
The brightness is
good, I can
