-
- Yes help, We have a 3b2 310 ( Buckhead Amateur Radio Club )
- and it has taken a turn for the worse. It is a 310 72Meg HD
- 2 Meg real.
-
- Currently it just sits there both power and diag lights
- light but no flashing and no firmware prompt.
-
- Unfortunately the club cannot commit to a large repair ticket
- and being electronically oriented are soliciting any advice.
-
- Heres what happened:
-
- Hit big red switch to on
- Wait Wait Wait ( get impatient )
- Hit big red switch to Standby
- Console prompt flashes on screen init level 0 begins
- System shuts down by self.
- Hit big red switch and does not come up power and diag led light.
-
- Have tried the obvious like
-
- Try other terminals for console
- Open case and listen for H Disk sounds and sounds OK.
- Look for burnt parts.
- Feel chips for heating.
- Try voltage measurement on a few chip pins (+5V).
- Remove 2nd MEG of real.
-
- The only result was I felt that the main board runs hot
- which may be normal. One coincidene is that the ATT 610
- terminal appears to have died along with the 3b it will
- rcv but not xmit. It was not used as the console during
- death of the 3b2 but was used subsequently. May be a clue.
-
- Again any advice or sources for parts and service at a reasonable
- rate would be greatly appreciated.
