Eygo Monitor
Question from Chris: Hey guys, I hope you can help me with a question about an Eygo monitor I recently picked up. On Bob Roberts “what’s my monitor” page the monitor is listed as an “Eygo Old Style” When I got the monitor it worked but there was some curling of the screen on the right side…needs a cap kit I thought, but other than that everything looks good. When I tried to turn the game on the next day, nothing. No image, no raster, nothing. I tested the fuses, tested the HOT, tested the voltage regulator, rectifier diodes, everything checked out fine. I pulled the chassis, touched up some solder, put it back in and it fired right up. I turned it on & off several times and it worked perfect. Tonight I turned it on and back to nothing again! I haven’t done the cap kit yet(mostly because I pretty much have to assemble my own cap kit since it’s an odd model) Could a bad capacitor, like in the B+ voltage circuit cause something like this? I’m not sure what to do to keep it working? Maybe I didn’t touch up the right point but flexing the circuit board when removing & re-installing it caused a momentary connection? Any help you can provide with what you would do facing this situation is greatly appreciated.
Also, Tim mentioned in a podcast from about a year ago that he would like to have a Bad Cat’s pinball machine for his wife. Did he ever get one? Thanks again!

Response from Jonathan: Chris,
> Could a bad capacitor, like in the B+ voltage circuit cause something like this?
Yes, it could be a bad capacitor in the B+ voltage circuit.
> Maybe I didn’t touch up the right point but flexing the circuit board when removing & re-installing it caused a momentary connection?
Yes, you could have caused it to make a connection while you were removing and reinstalling the chassis.
These are both plausible circumstances. In our experience, however, this is usually a cracked solder joint somewhere on the high voltage line. You might follow from where the AC power comes into the monitor chassis and just trace it along the board touching up solder joints as you go. Of course, the curl could indeed be a bad cap so you might try doing the cap kit as well.

Funny you should mention that. Tim and I were just talking about Bad Cats at the Texas Pinball Festival last month. We’ve seen a couple of Bad Cats pinball machines since we mentioned it on the podcast but they are always more than what he wants to pay. I think he’s waiting for the right deal to come along. =)
Hope that helps, Chris. Thank you for your question and good luck with your repair.
