Display Netplex Link Down and no LEDs on CPU

<< < (2/2)

lookes:
Even without the software mezzanine board installed, a 1270 should have all LED's lit with the red one flashing slowly.

I just took another reading at the backplane and the 25V point was 23.94V.
Is that enough of a drop to cut off the CPU board?
Just curious..

24v is fine. If you are sure the power supply is OK, (Best to try a known good one) then you probably have a fault in the 3.3v supply on the MPU.

I have no other power supplies to try but a MPU board issue sounds logical.
I have no idea how to check that. there is a burnt spot on the board which was there at C38 when i bought the machine and with that it still worked fine.
I understand you fix 1270 boards? Can I send this off to you? Please let me know how.
Thanks,
Mark
