Hi - I installed my recently purchased Indivision AGA MK3 in my A4000D but so far I've been unable to get any signal from it. I've connected the SVGA output of the Indivision to a late model CRT (PC) monitor. The monitor works fine connected to other computers with 31kHz / SVGA compatible output (A3000, PC).
The Amiga 4000D's built-in output on the 23-pin / 15KHz port works fine (connected using my previous setup of OSSC -> HDMI to SVGA adapter) and the computer is functioning as expected. The A4000D has been recapped about 6 months ago and works well.
I've tried:
- Re-seating the Indivision on the Lisa chip
- Cleaning the pins of the Lisa chip with isopropyl alcohol
- Connecting to a different monitor (same one that I use with the Indivision AGA MK3 in my A1200).
- Tried both the SVGA output as well as HDMI
- Verified that the ribbon cable is seated fully on both ends
Neither monitor I tried recognizes that any signal is coming from the Indivision - they both go into power save mode.
Close up photos of the installation and card are here:

What else can I try in order to troubleshoot?
Thank you for your help.
