I have a Rescue 911 that will not boot about every 10th time turning it on. If I turn it off and back on it will usually boot. But it might take 1 or 2 times of doing that. When it doesn't boot the back box lights come on but no other lights. The DMD does not display anything. The LED on the control board and display controller light up and stay light but they should blink. The LED lights on the sound and aux sound boards do not come on.
I have reseated all the connectors. And I tried wiggling them when it doesn't boot but it does not help. I tested voltage for the CPU at P1 connector at pin 1 for +5V and pin 4 for ground. I was able to test it when booting fine and with a boot failure. Both times it tested at +5.08V so I don't think I have a power problem. Any ideas what to check next?
Thanks in advance for your help.
