[tonyhtbsusa]

I had one do the same thing 
Power supply cables were loose
Unplug and plug back in cables
You will find the bad one

Hi can anyone help me with and issue i have with my fluke 9010a when i power
it up theres no display showing and it beeps once and at power up then goes
silent for a few seconds then starts beeping non stop like its trying to
reboot i have swaped a my keyboard and display into a working fluke 90101a
and it works good my issue is in the main control board i am following the
trouble shooting procedure and i got to this problem i tryed to troubleshoot
the watchdog reset circuit and when i use the probe in sync-free-run pulse
low mode momentarily connect the probe tip to u31 pin 4 of the uut i get a
beep but no display message shows up nothing its supossed to show a message
fluke 9000 power up ok ver 3a i did check all grounds and power at the check
points and did check the ribbon cable between the display keyboard and main
control baord its all good something seems to be blocking the display from
going on the watchdog chip has been changed and no luck does anyone have any
ideas let me k  now thanks
