Amiga Hardware Issues and discussion / VERY Dim video output from Amiga 4000

Amiga 4000: Is the Fastlane Z3 the best home for a BlueSCSIv2 Upgrade?
When I filmed that, I had to post process it A LOT to increase its brightness to acceptable levels for this video. I had assumed that the issue was to do with the RGB to SCART cable (unlikely) or that my trusty SAMSUNG LED with SCART was on its way out (more likely).
However, today, I tested this by plugging in my A500, and the video looks bright and clear, as I remember it. So, A4000 has a problem .
Calling on the ancient wisdom of the Amiga collective. Would anyone know what this is a symptom of?
My guess, if I were someone else, would be that capacitors were going down the swaney, and providing too low voltage. However, I had this machine re-capped just last year. So its very unlikely this is the issue. However, the recap was because of some leakage in the video area, however, I was lucky in that it seemed to be early days. I have cleaned that area, so Im surprised if its on-going corrosion.
Anyway, over to you guys. Wondering if Christ Edwards lurks here, as I would assume he might recognise the issue...
