It is likely possible - you would probably need to make your own adaptor by splicing wires together though - I am not sure if sound would be taken into the display adaptor via hdmi/mini display port, or if it would have to be a separate 3.5mm in - have a Google about as I think some other people have tried doing this.
I just removed the speakers from mine, as always used external ones anyway :-)
In short - yes; you are basically taking all the internals out the imac, leaving just the screen then adding in the necessary hardware to power and drive the screen - you would find a power supply on ebay / Amazon; most likely would be 12v 5A, but that would be dependant on your driver board. Some places sell power supplies with the driver boards, but I would probably be more inclined to find a higher quality supply with reviews, shipped from whatever country you are in. I happened to have the required power supply from an old 19” 4:3 LCD monitor that met the specs. This subsequent guide has a little more info on the initial steps - How to Identify The Make & Model Of An iMac's Screen, In Order To Buy The Correct Video Driver Board
Thanks for letting us know and glad you got it fixed :-)
Hi there, I can’t say for sure - CCFL backlight tubes do tend to dim over time, but if it was working brightly prior to this, that seems less likely.
Are you using it connected to a Mac? My screen was overall very dark when I first used it (not the backlight as such, just all the colours etc) and to correct this, I needed to calibrate the screen (https://support.apple.com/en-gb/guide/ma...) so I would try this if you have not yet.
The controller I have does not have controllable backlight, but there is a noticeable brightness between colour modes - I would try all the different settings when pressing the menu button.
Lastly, if none of that helps, it could be the inverter supplied or your power supply is underpowered?
All possible, but make the build a lot trickier;
- The PATA (not SATA) optical drive fills the space the main driver board and cables connectors sit, so would need to find an alternative location for the driver board. At the point I did this, the included drive was almost dead, and couldn’t remember last time actually used a CD/DVD.
- The screw mounts holding the speakers in place were actually on the logic board, so you would need to add new suitable mounts. Also have a power supply for an amp (probably usb). Lastly, I never actually used the internal speakers as they were pretty poor.
- Not keeping the iSight in place was a regret especially since I have lost the mount for it, although I have now mounted the iSight in a small external box which sits on top of the screen. Also need to wire the analogue microphone to a 3.5mm output (and use with a male 3.5mmTRRS (4 pole) to 2x female 3.5mm adaptor if using with a MacBook). This unfortunately isn’t supported via Bootcamp.
Let me know if you try this though!
Hi Franchesco, your comment prompted me thinking and I found the iSight camera I had taken out - turn out it is pretty simple - the camera cables are standard USB colours (red, green, white, black), so a quick splice together and it works!
I have not got the microphone working (it is an analogue output, so would need to be input into a microphone socket) and my screen less MacBook’s internal microphone picks up my speech fine, but might try this further before I solder the wires and mount back inside the iMac case - thanks for the inspiration!
It is probably not impossible, but probably tricky - don’t believe the iSight camera is USB - it has separate video and microphone cables.
I just removed the camera, as never used it - how times change!
Maybe try commenting on the camera replacement page? Might be simpler to try and find another webcam that would fit in that space.
This page seems to have a manual with pin outs http://www.datasheet39.com/download.php?... (scroll down to and click “Download[ LM240WU2-SLB2.PDF Datasheet ]”
Afraid not, as I have no details of that now - just search eBay for your LCD screen model number and get something from a seller with good rating and the item looks similar! (Input board, inverter board, controller board + cables - presuming you are doing this process for the same iMac model as I did)
Thanks for pointing out this though, I have updated the guide accordingly.
Good luck - sure that will work fine :-)
