Rami,
I still don't understand "bands flashing".?? Are you saying that the display for frequency flashes?? That occurs when you are trying to transmit on a frequency the radio is not programmed to transmit.? However it flashes "TX Error".? Can you enter the display menu 11?? Press the F key once and rotate the select knob (lower left) until the display shows CHG VLT DSP.? Press the B button underneath the display until the voltage appears in the upper left of the display.? What does your radio show?
