Hey all,

Picked up a Raiden machine today. I tried it out about a week ago and it looked pretty good. I actually picked up a few machines, and moved them very carefully (well, as careful as you can on terribly paved roads) back to my place. All was well with my newly moved machines, with the exception of Raiden.

I've downloaded the manuals, and am starting to dig through them now. Obviously I'm hoping that something wiggled on the drive, but if it's worse, this will be my first project. Love this game, and was sooooo looking forward to getting it.

Pics are below. I can put a coin in it, start the game, move the ship, fire, bomb, and hear all of the sounds. You'll see the idea in the pics. Almost like there's 2 images overlaying themselves on top of each other. It kind of pulses, so the pics may not do it justice.

Gonna take a peek that everything is intact tonight, and I am schooled enough not to give myself a mighty shock. :) Anyone seen this before?

The chasis says WG 19K7901. Looking at the actual monitor and lots of numbers... Trying to identify it. Sticker on it says WNA E32526. Also LR18493. Gonna at least try some of the picture controls and see if it makes a diff, and then dig more to identify it.

Thanks,
Sean

Open the back, and check every connection: to the monitor, the harness, the power supply, the neckboard - anything that may have come loose on the journey home.
 
Thanks

Thanks... I unplugged it, and read all the warnings (been reading for about 4 days on here) and just didn't want to get fried...

I'm playing with the vertical hold and it appears to be helping. Using the mirror trick cause the wife and kids aren't home (thus why I moved a bunch of games in here when she couldn't tell me a bad idea)...

The vertical hold did wonders. Tweaking it to try and get it just right. I did also push on lots of key connectors. Shouldn't do a bunch of things at once, cause then you never know what actually fixed it. :)

Gonna keep tinkering safely...

Update

Well, good news and bad. I tweaked everything, and the game played great. Shut it off and fired it up in the morning again. Got another crazy looking screen and I could tell it wasn't the game just in a speedy vertical scroll.

Powered it down, let it sit, and plugged it in again. Came up and I could see it was the game, but it was vertically scrolling real fast again so I adjusted, and all was well.

Another time I had it looking good, unplugged for an hour or so, plugged it back in, and saw the game but it was in a quick vertical scroll again. Will suck if I have to adjust the vertical hold each time. Gonna start more reading now, but wondering if anyone has had this issue before? Well, I guess it's 2. Sometimes the image that's messed doesn't seem to be the game, but it does make the sound when I insert a quarter. The other time it just needs the vertical hold adjusted. Seems as though the vertical size resorts back too, almost like I have to reset it each time.

Thanks for any ideas you may have...

More info

Been futzing with stuff. Seems as though if I leave the game off for a while (hour or more) and turn it on, the vertical hold is all off again. I set it, and after 10 minutes it starts creeping, and I set it again, and it seems to just hold as long as I leave it on.

Something is definitely up as the monitor seems to take a bit to fire it up if I shut it off for the night. I get the glowing thin vertical line for a bit, and then it comes up in speed scroll mode.

Anyone heard of this? Off to do more reading...

Thanks,
Sean
 
Cap kit, possibly bad vertical hold pot, possibly cold solder joints. I recommend a cap kit + replacing the vert hold pot + touching up any suspect solder joints. Should be relatively bulletproof after that.
 
Thanks

Thanks for the response... Took a look at the caps and such, and I definitely see a little more than dust on there. I'll give it a closer inspection and prepare for a little work. Thanks much for the response. I'll let you know how it turns out...
