Amusingly enough, I live about 10 minutes drive from MartyBugs. (Hi Martin -- if you ever find this post)
His experience is exactly the same as mine
I will admit to making one major mistake once. I fitted the 25V capacitors where the 10V capacitors should have been and vice versa. It was only after I'd put it back together and tried it out that I realised (I looked at my diagrams and the second monitor and thought -- hang on, that's backwards!)
Fortunately, in my case the capacitors survived the brief over-voltage, and once swapped over lived happily for some time.
If what's happening to you happened to me, I'd open it up again and check the capacitors. Did I place them in the wrong place, or the wrong way around?
You have before photos, so checking should be pretty easy.
Let me tell you another horror story. I purchased some capacitors and when I pulled them out to use them (I bought more than I needed for 1 monitor and these were leftovers) I found that they were already bulging! So it is possible to purchase capacitors that are already bad!!! I'd note that the supplier was a trusted one.
So it is possible (although I'd hope unlikely in the extreme) that the capacitors you used were already dead. (If anyone doubts this story, I think I posted about it just after I started here. I would not have believed it myself if I hadn't cut them from the tape myself)
