Title: Strange behavior from one of my A1 V32s
Post by: RetroGamerJP on August 03, 2020, 01:18:50 PM
I have both of my V32s on the same power strip so when I flip the switch, they both get power simultaneously and typically boot at the same speed... however, the last few times I have noticed that I power on, it appears in one of them, the MPU is not booting properly, the screen is just blank and you don't see any of the usual text post. It takes me flipping the ATX switch on the MPU off/on and then it boots fine.


It's not the monitor or power because when I first turn on you can see the monitor is powered on with he "no signal" that flashes up for a split second. then it goes blank and just stays that way (until MPU is cycled)


Any ideas what may be causing this? is it a symptom of a bigger problem heading down the line?


I did re-seat the RAM and Video card as well as all the connections but symptom still remains.




Any insight would be greatly appreciated.

Try turning your A1's on/off from inside machine.  Turn on all 3 switches from left to right and turn off all 3 from right to left.  See if this fixes your problem.

Thanks, that is essentially what I am doing now and yes, it works that way. But I am wondering why all of a sudden this machine requires this and why my other V32 is fine when I just leave all switched on and just cut power on/off to cabinet via the main power cord.

It's because you are supposed to turn on power to backplane before mpu. Some MPU's are more finicky than others and will work off a strip, but you are not supposed to do that.  I always power up using the switches inside, I know it is an extra step, but that is the way the machine was designed to work.

Understood, thanks for the clarification. So really its not that the machine is question has an issue, it's more that I was getting lucky with the other one. I will follow the proper boot procedure from now on.


thank you gentlemen!
