Superstar 3900 weird issue
Posted: Sunday 16th Dec 2012, 3:14
Radio Make and Model: Superstar 3900 (single final)
PCB Number: EPT3600-14B
PLL Number: ?
Test gear available: multimeter, test light, bench counter (O-scope if I ever get it back)
Symptoms: radio will not turn on. ALL grounds good HOT (+) if power is applied to the unit, Basically all pins on all ICs, regulators and transistors all get 13.8v
What is working: nothing
What has been tried: tried desoldering audio IC, and transistors as well as the protection diode... nothing, also tried powering on with the bias board removed... nothing
Did it suddenly happen ?: radio was purchased this way for $10
Anything else that may be of help?: there is no continuity between the + and - connectors on the power plug... yet the chassis and all metal parts have a 13.8v+ reading when power is applied
