TXRX(Video)
Description
This message indicates that the radar video signal from the scanner is faulty.
If TXRX(MHV) or TXRX(Heater) is displayed, handle the error first.
Since this message is displayed even when the transmitter is not operating, first check the
magnetron current on the test menu of the display system, and check if the transmission function
is normal.
If the transmission function is abnormal, the modulation circuit CPA-264, the power circuit
CBD-1682A, or the T/R control circuit CMC-1205R may be faulty.
If the transmission function is normal, the receiver NRG-162A/NRG-229 may be faulty.
