This radio came in with the old man complaining that the reception was intermittent. Sometimes it would be just fine, then all of a sudden, it would go away completely. I could confirm that this was indeed the case and cracked open the radio to have a look inside.
Immediately, I could see someone had been inside this radio before me. The hot glue was most likely tried as a way to fix the rear jacks in place. This is a common fault on this radio. The pressure on the jacks when inserting the plug, puts a bending force on the through pins of the jacks, where they enter the PCB.
With the lid off, I now began to look for the source of the intermittent connection. This is best done by carefully using a large screwdriver and applying shock around the board in search of the area in question.
I initially thought it was the white connector, however, the fault turned out to be in the voltage regulator just below it in this picture. One of the legs had a dry joint.
The pins were all re-flowed with fresh solder and the radio was back working again.
