I've recently read that x-y monitors are very dangerous to test (http://www.ionpool.net/arcade/tech/bw_vector_monitor_faq.pdf) because of "lethal voltages." Is this a serious problem/danger? What do you recommend so that I am not killed?

How do I check the transistors? Thanks for your help!

My Asteroids Deluxe is showing only the left half of the screen. The other half is blank although you can see on the dividing line the lines where asteroids are in the y-position. I assume that this has to do with the x-output from the PCB somehow, but how can I fix it? Thanks!

I know that these are very rare but I wanted to see whether anyone has an Asteroids Deluxe cabaret CPO or knows somewhere where it is being reprinted/sold NOS. Thanks!

Hey, I have a blooming Asteroids Deluxe cabaret monitor. I know that you need to replace the HV diode, but I can't figure out where to get a replacement... does anyone know where I can get a replacement HV diode for my Asteroids Deluxe monitor?

Hey! I'm selling my Asteroids Deluxe full-size machine in the Urbana, IL area. The machine currently has a power regulator issue which, as far as I (and the other people on this forum) have been able to determine, can be easily corrected by replacing the "big blue" capacitor in the power...

Hey, all. I'm moving to New Orleans soon, and I was wondering if anyone knew of a decent arcade within driving distance. It can't be in a bar as I am under drinking age, and I haven't been able to find any other options. Does anyone have any suggestions!

Could the PCB's ROM error that it's reporting be related to this problem? That is, is it possible that I don't need to replace the chip at R2, considering the error appeared right before all the capacitor problems began?

I did click to AC volts and it did respond with an AC value. Does this mean that I should replace the "big blue" capacitor? Can I get one from Bob Roberts, or should I try to find one on the forum?

Does anyone know where I could find a decently cheap Asteroids cabaret in the midwest or in the area around Louisiana? I'll be up in MI this weekend, can pick up near IL during next 2 weeks, and can pick up near Louisiana after that. Has anyone seen/have for sale an Asteroids cabaret in those...

Ok, I've cleaned the PCB and replaced it... when I booted up I got the self-test very briefly, but then it disappeared just like the other time. Since my multimeter work has turned up nothing, I'm even more in the dark.

I checked out the link and the closest problems seemed to either stem from the power supply/regulation or from the PCB. He appears to advocate cleaning the PCB contacts with an eraser so that's what I'm doing now.

I've figured out my multimeter settings and have tested both the 10.3 and the 5 voltage tabs. Both of them appear just great, without any wavering of the needle or anything: the 5 clocked in at exactly 5 and since I'm using an analog multimeter I was unable to determine if the 10.3 was exactly...

I have a multimeter with a bunch of different settings for voltage: there's a big dial on the front and even within the selections labeled "DC V" there are 4 options (10, 50, 250, 500). Should I choose 10? Thanks again. Also, there are two different tabs labeled "GND". I assume this is...

Where can I find what the "normal" voltages should be? I haven't done much multimeter testing before, basically only continuity stuff. What setting should the multimeter be on, and what should the normal voltages be? Thanks for your help!
