Tech Update #3
for DX2547 with s/n before T1T01601
| Symptom: |
Some
voltage is present on the chassis of the radio. |
| Cure: |
Remove
the regulator transistor from the heatsink on the back of the radio
and check that the white mounting screw insulators are positioned
on the heatsink correctly. These white round insulators should be
mounted on the black heat sink material and not on the voltage regulator
pcb so that the mounting screws do not short the transistor case
onto the heatsink. |
