I have been working on a JVL Concorde 3 plus (counter top Game), the CPU is not running. All is does is beep about every 2 seconds. The Monitor is dark. The +5 and 12 voltages are good, tried different CD drive just in case it is locking it up. Battery is good at 3.5V. The one fan on the logic had a poor connection and may not have not been running all the time. Game cooling fan runs. Hooked the monitor up to a different signal source and it works OK.
On the logic Changed out 3 of the 1000 MFD caps with no change so then changed out the other 2 and fired it up and it loaded and started the CD drive, shut it down right away figuring it was fixed and put think back together then fired it up and I was back to the not running and just beeping.
Changed out the 3 - 470MFD Caps and fired it up and it started so let it run this time to fully load and about the time it got to the point where it should be letting me play it comes up with a error "program error" message. Rebooted the game and it went back to the just beeping sounds.
So can a weak battery hold corrupt info in memory and lock this thing up?
Will this thing run with out a CD drive installed like most mother boards (get you to Bios setting screen, or whatever screen it is)?
Any body run into this and have some ideas of what to try next?
Thanks
