[Kenwood] Dg-5 Not working. Help needed

[Bill Smith]

Hi Jim,

Quote from the URL listed below:

A majority DG-5 failures are caused by nothing more than an intermittent
opening of a plated-through hole connecting top and bottom foil paths of the
PC Board.

Before any component level service is attempted, it is advisable to
eliminate
the possibility of an intermittent connection causing or complicating
Counter failure.

There are very specific instructions to remedy poor solder connections in
this unit which are described in Service Bulletin #54 at the referenced web
site.  Don't know if this is your problem, but would begin here.  If not,
would look at the power supply circuitry in the DG-5.

Hello just got through re arranging the shack. As I leaned over the TS520s
to connect the DG-5 II accidentally powered everything off. hit the power
switch. I did this at the same time I was plugging in the power cord from
the DG-5. I heard a slight click/pop. I then noticed that the rig was on. I
shut everything down.  I then I turned it back on the radio was ok but no
display from the DG5. I then did the following.



1. I replaced the 2AMP fuse on the back off the radio.
2. Fired up the radio still nothing from the DG-5
3. Shut it down and checked the 2 Amp fuse it was blown.
4. Again I replaced the 2AMP fuse on the back off the radio.
5. Fired it up still nothing from the DG5.
6. Shut it down and found that again the 2 Amp fuse was blown.
7. I replaced the 2 amp fuse and removed the power cord from the DG-5 .
8. Fired up the rig and let it run for 30 minutes.
9. Shut off the rig and checked the 2 amp fuse it was fine.
10. Let everything sit for 24 hours. Plugged back in the DG05 Powered on
the radio.
11. Nothing from the DG-5, Shut it down and checked the fuse it was
blown



 The radio is working great. The Dg-5 was working fine prior to this
incident.



Any ideas??   Thanks Jim
