Donkey Kong Monitor Advice

[rob.hayes]

Hey everyone this is my first post on this community. My DK monitor is getting pretty washed out and wavey. I think it may be time for a recap. I have read various places to just get the full Sanyo 20EZ cap kit from Bob Roberts and replace all of them. In my case is this necessary? I have soldered some but never as much as would be required for a full recap. I have a buddy who is pretty solid with a soldering iron but I would rather not bother him with this project. Can you guys maybe suggest which cap(s) should be replaced, or identify if there is another issue?


Thanks,

Rob

I would cap the whole thing, you might as well if you're taking it out anyway, it's tough to narrow down which ones to replace to alleviate specific problems (at least as far as I know) and chances are they are all the same age anyway and should show issues at relatively the same rate.  Also measure your voltages while you're at it.

Can people point me toward a good guide? I found this one http://www.arcaderestoration.com/Journals/1/Photo+Tutorials/4/Sanyo+20EZ+Cap+Kit.aspx. And I have the Sanyo 20EZ manual PDF that someone on here uploaded. I'm just nervous about my first recap.


Thanks,

Rob

Agreed, replace all of the electrolytic caps and check your B+ voltage is 108VDC. If it isn't it's easily adjusted by tweaking VR601 on the chassis.

Take your time making sure the polarity of each cap is correct which is fairly straight forward.

Looks like your Donkey Kong entered a funhouse!

When you order from Bob Roberts, I believe he includes a map of all the capacitors (if not, I linked one below).  And I agree with everyone above, you might as well replace all of them if you're going to go through the trouble of taking out your board.  If one cap is failing, chances are the others are too.  Plus, trust me, the HARD part is taking the board out.  If you've ever done ANY soldering, the EASY part is the soldering.  (May not be true with other games)

The guide you found, is the same one I used to take out my board (and my cabinet survived LOL).

Robert Felstein (Jammvy) also has a series of 7 youtube videos for this:

EDIT: Now that I think about it, I recall several people telling me that for DK it's actually easier to take out the ENTIRE monitor chassis than to just remove the board itself.  Maybe someone who has actually done this can chime in.

Don't forget to discharge the monitor!  Dangerous voltages back there around the flyback.

Thanks for all the info guys. I contacted Bob Roberts about the cap kit deluxe. Now, I read the discharger he used to sell was good, however it is no longer for sale. I do not have a drill so I can't follow his instructions to build a replica. What to you suggest to discharge that boy? I read on forum where a guy used a long flat head with jumper cable attached to the shaft and then the metal frame.

Ideas?

Yep , a flathead screwdriver and a jumper wire with alligator clips attached on both ends is all you need.
