Great support people!!

JJP support is top notch as far as I've encountered. They'll take care of you.

Is the game working and playing (including the LCD) other than the playfield lights not working?

First thing to check, fuses.

Is this an older game or one of the newer unified power supplied games?

Make sure the connectors on the I/O board are seated (I believe J800, J802, J804, not sure if they are the same for the older games)

Looking at it some more, J804 does not appear to be used, but J802 is for the RGB control signals. J800 is a mini-USB to USB connector per the manual.

Following this.Good luck with your issue.Hopefully it will be a simple fix.

Usually its just a burned out light board, maybe 2. I had to replace quite a few of mine since 2013.

If one of the boards is bad you should be able to bypass it (with the jumpers and in the settings) to see if that solves the problem.

Unless you have one or two in a row, and then the cables are not long enough to jump.

Happened to me weekly. The machine was down more than it was up. The boards are not cheap either. Shipping is what was killing me, as any profit the machine made, it went to paying to ship bad boards back, over and over. I asked if I could just get a complete replacement and only have to go to the location once instead of multiple times, but that wasn't how it worked. I had to wait for them to fail, then mail them, then wait, then install the new one ... then head down in 2 more days to try and bypass another dead board, ship it, wait ... gah. Buh-bye.

Good luck! Fun game.

Somebody should sell a longer cable for jumping longer distances.

Anyone have a closeup pic of one of these boards?

I have the same problem with my Hobbit. JJP sent me a board. Im hoping it resolves the issue.

So what on these light boards goes out that only JJP can fix?

surface mount?

The older boards need a little daughterboard added that prevents the board from burning out. All the ones I've swapped are replaced with another board that looks exactly the same except for the addition of a tiny (1.5" x 3/4" approx.) daughter board with a surface mount chip on it.

Just curious about this myself. My RR woz once in a while doesn't start with any lights working. I turn it off and on and they work fine then. Is this common for any of you other woz owners?

My RR is almost one year old and I'm not experiencing any light issues. I would check the connections.

I have had this happen, I think its just a cold start on the PC, failed to initialize something.
It mostly happens to me when the wall power is weak.
Re-starting always fixes it.

OK, that's what I was thinking too. It's only happened a few times, but twice recently. Thanks

Yes. Mine has done that one time. I was told by Frank at jjp that it is probably some code related issue with the newest version. You just shut the machine of and power or back on.

This has happened to me on occasion but on my WOZECLE. Maybe once out of every 15 times I turn it on. Turning it off, waiting 10 seconds, turning it back on has always worked for me. This seemed to happen after I swapped the power supply board RMA JJP had going on. I also had updated the code the same week so not sure which was responsible. But it's never been an issue that I feel was worth reporting but would like to know if there is a fix.

Same here... Only on occasion, not a big deal, a code fix would be nice but in all honesty it really doesn't bother me even slightly.

I was told by Vic that it is likely not code otherwise more people would be complaining. He suggested I move the USB plugs around in the back. It is too soon to tell if that worked.

For those of you who are having this problem, I would put a ticket in just so they are aware of it. I know it is too infrequent to care that much about, but I think they should know it is a common problem in case it can be fixed by code.

The issue stems from noise in the power and data lines caused by static charges building up on the balls during play. Over a year ago JJP sent out static electricity isolating gaskets you would fit over the I/O shield of the PC case. Evidently this didn't isolate all problems. I also know at one point they replaced peoples' power supplies and sent out a new revision boards with a regulated 5v power source for each board piggybacked onto the power header. This seems to have solved the problem of boards freezing and failing due to voltage transients in the 5v power supply that drives the LED chain. I think the boards have little fuses that are soldered in? This terrible serial based design has been scrapped in favor of a parallel oriented data system in Hobbit and future games so if any boards fail on these it won't affect others in the game.
