Dreamcast still not fixed, complete tear-down

I really hoped that in this post, I would be telling you that I have fixed my Dreamcast. Nope.
I did a complete tear down of the main components and could not find any medical reason for the symptoms presented. It was like exploratory surgery. I will get a new AV lead from Ebay as a final try, but if that doesn't work then this Dreamcast shall become officially decommissioned and retired to a display cabinet.

Second attempt at fixing Dreamcast

Ok, the next thing to try was re-seating the power supply. This involves removing the PSU board, cleaning it and putting it back.

It was in pretty good condition in there, so that wasn't the problem. This repair is used for Dreamcasts that reset themselves, which is not the problem for me, so I was doubtful this would fix it.
Next thing to try is stripping the whole thing down and making sure there are no dry solder joints around the video out area. I hope there are, because that would mean the problem was there the whole time!

As soon as I can fix this thing, or at least exhaust all my ideas, I will start working on repairing N64 control sticks.

First attempt at fixing the Dreamcast

A fail. That's a good way to put it. I thought that the RF adapter may be the faulty component, so I soldered some AV leads onto the RF out inside the little tuner box.
This didn't work.


Well, at least I have eliminated the cables being the problem. I will probably get some new ones soon, just to be sure, but the next thing to do is check out the power supply contacts and give them a clean. I've read that the PSU board can cause various problems.

As soon as I fix this bad boy, you better believe that the solution will be up on the main site in a how-to form. I'm so keen to get this beast working...
