BULLETIN # 26
MODEL: DG-1
SUBJECT: SERVICE NOTES


It is our experience here in the Compton service facility that the 
vast majority of DG-1 problems are not component failure, but cold 
solder connections on the digital circuit board X54-1160-00.

The second most frequent problem is dirty Molex connectors between the 
two circuit boards in the DG-1.

Recommended service procedure:

Remove both boards.  Using a fine point, low wattage iron (45 or less), 
and a good quality low flux content solder, carefully resolder all component 
side connections plus the print throughs containing no components.  
(There are 18 of these points-only one is not accessible from the top, 
but is located under IC11 and can be resoldered from the bottom.)  
Resolder the Molex connectors.  There are 9 print-thru's where solder may 
not have flowed thru to the component side.

Using a good quality tuner cleaner with silicone lubricant, spray both 
boards Molex connectors and work the pins in and out 3 or 4 times to 
insure good contact.  Rassemble and final check.

Total time on the bench:  20 minutes.  We will allow up to 1 hour 
only if in warranty.
