I figured it might be interesting to document my adventure with repairing my new X'eye that has no video output. So, let's start with day 1.

Day 1:
Bought the X'eye, took it home to test it.
It powers on, and both the Power and Access LEDs work!
Wanted to finally start playing some Sonic CD so I hooked it up through the male to male RCA jacks.
Audio outputs fine, I can hear the X'eye BIOs audio, but there's no video. Eventually Sonic CD boots up, CD reading works fine.
Remove Sonic CD and test the cartridge slot. Same issue, audio works through both RCA audio outputs, but no video.
Grab a 9 pin Genesis RCA cable and test that video output slot. Still no video, but audio works through this as well.

Assumptions: Some issue exists along the video circuit. I don't have a full circuit diagram for the X'eye so I'm basically going to poke everything with a DMM.


Day 2:
Stealth mission for my DMM is a success!
Quick DMM advice for anybody looking to start DIY circuit repair. Don't get a cheap one. Get a fused one. A cheap non-fused one can blow up in your hand or on your desk. A fused one will just blow the fuse if you hook it up wrong.


Google fu brought me to this topic on Assemblergames that lists all the X'eye capacitors, their capacitance, and voltage rating. Bookmarked!

After poking around at all the caps and doing some math there are a few that are some caps giving out bad readings. It seems lucky that everything but the video output works. Next plan is just a full cap replacement. It seems like a good idea and while I'm at it I'll replace my Game Gear caps. This will be quiet until mail day.

Very interesting!  I have an X'Eye that I use as my main Genesis machine, and it's worked great for the last 14 years, so fingers crossed, but I'll be very interested to read more about what you find.

Update?  I'm curious how this turns out.

If it matters, MetalFRO, the X'Eye can't play Jurassic Park (SCD). One of those "oddities" of owning an X'Eye.

It can't be played on a CDX either.  Don't know why it doesn't work.  Eye of the Beholder is another one.

Yeah there are some compatibility issues, but most console revisions have some weird problems like that. I'm just waiting on caps in the mail, I spent too much money a couple weeks ago, so I didn't even order them until this last Friday.

Interesting to note about Jurassic Park and Eye of the Beholder.  Interestingly enough, however, it will play CD-R copies  :laugh:

It looks like certain systems won't play certain games, but others will. I've seen scattered reports about 6+ games mentioned here:

I know a friend's CDX won't play Jurassic Park, which is unfortunate since it was the reason he picked it up.

Yea, I tried it on my CDX and was really excited for it.  I believe it played but the graphics were very distorted.  I was disappointed about it because I was never able to try this game out.  Eye of the Beholder was another I was excited about but couldn't play.  Luckily, I played and beat the PC version.  I'm assuming the versions were the same.  I think Eye of the Beholder wouldn't even boot up on a CDX.

Jurassic Park would boot and hang on the first transition for my friend. He borrowed my SCD Model 2 to play through it.

Fix it yet?

Can't solder right now. My soldering iron for work is stuck in the back of a truck halfway across the USA. I was planning on a solder station for home with tax return money, but mine took too long and were fudged up. I have to spend my days twiddling my thumbs and waiting for my amendment.
