JTV-89f no Variax no Workbench red Led

Recommended Posts

Jtv-89f:

No Variax/Do not connect to Workbench/USB flashing red.

 

-DSP is changed.

-Battery=Ok

-Tested with Cabled power kit=no difference

-Paper trick/removal of hat on knob=no difference

-Tone/volume and standard pickups=Ok

-Watchdog seems to be up and running (U12/pin 2)

 

TP1: -4.5v

TP2: 3.28v

TP3: 4.9v

TP4: 1.0v

TP6: 3.28v

 

U17(pin 21): 3.3v

TSR jack: 3.3v (Pin 2/J7)


The only thing I notice is that LED under modelling knob turns red once when you insert the tele-connector. But...pushing knob wont turn on Variax functions.

 

Please help
 

Thanks,
