| Capacitor map for the Apple IIgs AppleColor RGB Monitor? |
Posted by: Huxley on 2024-11-06 19:49:04
Hi all,
My trusty Apple IIgs RGB display is starting to show its age - it works (mostly) but the image starts flickering wildly after it warms up (literally - this display gets quite hot after a while!).
I'm already planning to do a bit of solder reflowing just in case it's a cold solder joint that's causing the issue, but I've also ordered a full set of replacement capacitors from Console5. All the other items I've recapped to date were pretty well documented, including some nice beginner-friendly capacitor map images I could refer to while doing the work. Unfortunately, I've had no luck finding a "cap map" for this display - if any of you have one, I'd be grateful for a link or hookup!

I don’t, but I’ve always noted how abnormally hot these monitors get and wondered why. Many years ago when I lived in an apartment without AC I was always afraid to keep it on too long during the summer when it was hot because the thing literally felt like it was several degrees away from melting.
I wouldn’t be surprised if the issue is a solder joint similar to what happens in the classic Macs without fans. |

I wonder if anyone ever made a "Kensington SystemSaver" type fan attachment for these displays? Or if something like that could be designed and 3D printed, perhaps using a fan that wouldn't introduce too much magnetic interference?

Honestly I ran mine for many hours in pretty high ambient temperatures and nothing bad ever happened. I did have to touch up the solder joints after many years though. If giving the monitor a good smack on the sides makes the picture react than you definitely have bad solder joints. |
