Updated AsRock X570M Pro4 3700x system from 11.6 to 12.0.1. Lost the I211AT onboard network card. Wifi still worked. Updated from 12.0.1 to 12.1 and lost the BCM43224 WiFi because Airportbrcmfixup.kext crashes the boot. Everything worked in 11.6 but not so lucky with 12.1. OC 0.7.6. Still...

Fought with a relentless kernel panic for several days. Could not even boot the 11.0.1 installer. Same issue related to IOUSBFAMILY and IOUSBHOSTFAMILY Kexts in the KP backtrace. Two systems, one Ryzen 3700x and the other an Ivy Bridge. Using OC 0.6.3 all green check marks in the Sanity...

There was a few of us who built 17" iMac G4's a few years back and made this error. Fortunately didnt get stung with a failure before realizing the voltage issue and getting it reworked properly. Cheers

I can appreciate that you've done a lot of work to get your configuration functioning, its not easy. I don't understand, however, why you've chosen the connecting block method as shown in your post. Other mods have had success using this part as it is directly pin size compatible with the LCD...

I used the pinout diagram the Kiwi supplied with his build a few years ago. Its flawless. https://www.tonymacx86.com/threads/kiwis-next-project-imac-g5.107859/page-9#post-764179

I recently embarked upon a fun little project to re-purpose a couple of older USB WiFi sticks into Apple A1181 Bluetooth Sticks. The WiFi sticks weren't being used anymore and I had a couple of extra Apple BT modules in the closet, so I grabbed my dremel tool and soldering iron and set to work...

Thx carl. This is my 4th one of these A1076 units. In my opinion, they're the primo iMac to mod. Nothing touches them. I made one significant breakthrough in this one, in that I found a way to isolate the USB ports from each other and re-use them by soldering to the leads on the backside...

It'll be a necessary first step to test and label all pinouts from a running 24" Machine to determine which wires are which. I may have found one on CL, see if it works out. So far haven't been lucky in finding any info from this being done previously. Cheers Ersterhernd

Back in January I purchased an absolutely pristine iMac G5 A1076 20" and a BNIB NUC D54250WYK on Craigslist, on the same day! Spent the last couple of months working on another build. Everything works great, including stereo Apple Chime at startup. I'll add details to this post when I get...

Is there no way to use the controller board to control only the LVDS signalling and NOT the backlights? I'm wondering why you'd need a special aftermarket PSU in there when re-using the iMac PSU has been done numerous times before in other models. I'll look into this further when I actually...

I could not get any continuity from the ethernet port to the solder points on the backside of the logic board. Theres some form of powered switch in the port that 'turns it on' when the iMac starts. Thus I could not get it to work. Also be careful as the LED power function runs through the...

No, the A1076 panel behaves itself and shuts down like it should.

Yes some iSight G5 LCD's do that annoying color loop when going to sleep or powering off. Too bad about your G4 Panel. I hope you can resolve the issue successfully. Cheers

The white wire shown in the photo is a standalone separate one, it goes to ground or pin 17 on HDMI. The shielding can be soldered to a heavy gauge wire and grounded pretty much anywhere. If you're using a block connector to HDMI then pins 18 and 19 can be directly connected via a 1k resistor...

Hi FlyingApple, Could you post a link to the LVDS converter you purchased? I'm interested in pursuing this mod as well, but am perplexed by the LVDS and 75w power requirement for the panel backlights. I've only modded TMDS systems up to this point, in various forms. Thanks Ersterhernd
