The cable was glued to the circuit board. The glue appears to have dried out and the cable is now detached. Any advice on how to reattach (I can align |

Should reads as "I have 14.5 volt at C816 with IC805 pin 2 floating"

|28-01-2009||If that so, check the voltage between Collector to emitter voltage, from datasheet of 2SB1548A the maximum voltage is 80V and base to emitter is 5V maximum and the collector current is 3Amps max, check it maybe over voltage or over current caused by the l|

|28-01-2009||You would not want any conductive glue for attachment of a ribbon as it will effectively bridge every trace?. I have never seen a ribbon-to-pcb connection only by means of glue?---it is normally used more as a re-enforcement of the connection.
