Einleitung
Diese Anleitung zeigt dir, wie du die LED Treiberplatine austauschen kannst.
Werkzeuge
-
-
Befestige einen Saugnapf in jeder der oberen Ecken der Scheibe.
-
Wenn der Saugnapf sich nicht festsaugt, dann versuche die Scheibe und den Saugnapf mit einem milden Reinigungsmittel zu säubern.
-
-
-
Hebe die Scheibe vorsichtig senkrecht zum LCD an, gerade soweit um die Metallstifte, die oben an der Unterseite der Scheibe angebracht sind zu befreien.
-
Ziehe die Scheibe von der Unterkante des iMac weg und lege sie sorgfältig zur Seite.
-
-
-
Ziehe das Flachbandkabel für die Vertikalsynchronisierung aus seinem Sockel auf der LED Treiberplatine nahe der oberen linken Ecke des iMac.
-
-
-
Kippe das Display weit genug aus aus dem äußeren Gehäuse, um das Kabel für die LED-Rückbeleuchtung von der LED-Treiberplatine zu trennen.
-
-
-
Drücke die beiden Hebel am Verbinder des Display-Datenkabels zusammen, um sie vom Sockel auf dem Logic Board auszurasten.
-
Ziehe das Display-Datenkabel aus seinem Sockel auf dem Logic Board heraus.
-
-
-
Ziehe sorgfältig das Display zum oberen Rand des iMac und hebe es aus dem Gehäuse. Achte darauf, dass sich dabei keine Kabel verfangen.
-
-
-
Entferne die beiden 9 mm Torx T10 Schrauben, welche die LED Treiberplatine am äußeren Gehäuse festhalten.
-
-
-
Hebe die LED Treiberplatine aus ihrem Sitz im äußeren Gehäuse. Denke dabei daran, dass sie über das Kabel der Gleichstromversorgung immer noch am Netzteil angeschlossen ist.
-
Löse das Kabel der Gleichstromversorgung, indem du auf den Sicherungsmechanismus drückst und den Stecker gleichzeitig aus seinem Sockel auf der LED Treiberplatine heraus ziehst.
-
Um dein Gerät wieder zusammenzusetzen, folge den Schritten in umgekehrter Reihenfolge.

How does someone tests to see if a LED Driver Board is broken or not?

Same question as above, how to check if it's power board or LED driver board that is damaged?
It might not be a complete answer but I had to change my LED Driver Board when my display went black ( as if the computer was in sleep mode ) as soon as the computer was on. I had to push the power button to get the screen back multiple time. There was also a problem with the graphic card but even after changing the GC, the screen would go black. We figure it was the LED Driver Board when we realized the computer wouldn’t show anything on an external monitor. Hope it helps :)

I have the same problem Mary. The imac starts but no screen and i need to shut down/turn on a few times until i see the normal screen. Very ocassionally the screen blinks too or turns to black and i can only see stuff by flashing a light to the LCD. Where did you buy the LED Driver Board?? Can’t find it anywhere..
Very easy to lift the glass out. Don't jerk too hard.

Another comment on DATA & LCD Temp. Sensor cables: I had to remove the vertical sync, and the backlight cable, however, if you have an assistant or/can carefully rotate the screen clockwise/and then have it held up about 5" to 6" at a slight angle, you do not need to remove LCD data cable or LCD thermal cable, however - IMPORTANT: you must have a second pair of hands/or way to securely prop up the LCD. Also, don't rotate too much, since then you will pull out LCD data cable, and it renders the whole exercise moot, or can damage the cable or connector.

You don't need suction cups. The screen, held by magnets, can simply be pried off using a very thin blade such as a screw driver and fingers.

That's a bad idea. using a metal tool to pry off glass is likely to end with an expensive broken front glass.
Suction cups are common. Find a couple and do it the safe way. I use some cheap ones that came with iPhone repair kit.

No need for suction cups, I just stuck my nails (short like guys usually have) between the top part of the screen and body, and it came off easily. I've never done it before, so it seems to be very easy.

Nails worked for me too

Just completed the replacement of the optical drive with an SSD using an OWC Data Doubler kit. Attempted to remove the optical drive without disconnecting any cables but found it a bit fiddly to orient the screen for good access. I bit the bullet and disconnected them and found the process less daunting than I imagined. Reconnecting them was similarly straightforward if you're careful.
Tip: you can skip the step for removing the optical drive thermal sensor connector from the motherboard. Still need to remove the sensor from the optical drive but you can leave that hanging and reattach it to the SSD later.

I use Garmin GPS suction cup. Work very well

I’ve just successfully installed a 1TB SSD in place of my optical drive thanks to the information here- thank you to everyone who has contributed!
3 comments- the procedure described here seems to vary between HD replacement and dual HD/optical drive replacement. This can be confusing at times.
Expect there to be minor differences between the layout described and what you find when you open up your iMac. There are also, surprisingly, differences between the HD enclosure description, and the article provided by ifixit.
I was able to replace the DVD/HD enclosure single-handedly without fully removing the LCD, or deconnecting any of the cables (steps 5-11). It’s a bit cramped, and fiddly, but I was not happy removing any of the cables despite watching videos, etc., since they all seemed to involve applying more force than I was comfortable with. A more detailed description of how to release them might have helped, but even here, there may be minor variations even within the 2389 model.
Good luck!

I did it several times with one suction cup at the end of a kitchen brush. Once with the blade of a swiss army knive, also ok. And i’m pretty sure it works with fingernails too

Fingernails are all you need to free the glass from its magnetic hold. If you don’t have them, slip something thin and plastic, like a spudger, at a top corner.

Minha dúvida é a seguinte: após o técnico trocar o HD do meu iMac de 21,5 polegadas, a câmera parou de funcionar. Seria por causa da troca do HD? Tem solução?
Claudio -
Creio que o cabo da camera não foi plugado ou deu mau contato… ou até danificado.

I can’t get my glass to budge. I’m replacing a cracked one and now it’s about to shatter.
jamboxmitchell -
I know that I'm replying really late but I advise to use clear tape over any cracks so the cracks don't get bigger

Check for chips in the glass BEFORE you do this step. If there is a chip when you pull up with the suction cups you will wind up with a jagged mess. If you do have a chip I would advise covering the screen near the chip with clear tape of some kind before lifting out. Mine shattered right at the chip and the resulting glass dust cloud got all over. My solution was buying a new glass screen.
