I have the same problem as above - intermittent green light, no transmission. Red light charging OK. Slapped its bottom and green light comes on, but only for a minute or so. Lots of static volume but will not tune in. Would appreciate any help you can give me. Cheers.

I found this and incredibly it worked for me too!

Just use another power strip

"...I realized an extra device had been plugged into the power strip. It appears the strip may have been overloaded. Tried again with a new strip (careful not to load too many appliances this time) and the green light came on properly."

I tried every input signal and no dice, then I just unplugged and reinserted the power in the same strip. It started working immediately.

simple and effective solution. Thanks!

Who would have thought that a power outlet would discriminate power usage? (:

No green light?

Disassemble the transmitter and tap the crystal with power on. use non conductive tool !

The crystal is up front and has a shiny case.

I suspect a component value has changed and the oscillator circuit fails to start.

By tapping the crystal it starts the oscillator.

This makes the unit work until power is removed.

…or give the unit a sharp slap with the palm of your hand…that gives same result

..anyone have a circuit diagram to post? I may be able to determine the fault.

We'd had a thunderstorm the other day and our house power flickered - that must be when it stopped working.

No green light with any input. After I unplugged the power supply and then reinserted it the green light came back, we were working again. Phew!
