I recently went through my entire collection of consoles and computers to see what worked or not. Unfortunately my PC Engine GT is one of the casualties of time. As I understand it, the problem is not uncommon. The machine powers up but only shows a black screen with the backlight on. No amount of jiggling with the Hucard gets a response. I've taken apart the system and found at least two capacitors that seem iffy. While these probably need replacement, and indeed the rest as well, are they the direct culprit for the problem I'm experiencing? Here's a link to some pictures of the two caps that I'm talking about. imgur.com/a/6OJ3ZZi

The first one is responsible for brightness and sound via some potentiometers I think, and the other is in a cluster by the power input. Since it's turning on, these are probably fine. The culprit for a black screen is usually the cluster on the other side of the board from pic 2, clustered around the transformer t500.
But yeah, you'll need to replace them all, worst case they'll leak corrosive fluid over important components and eat through traces/pads, so the sooner the better.
