+# VTX troubleshooting:
 
-The Red LED is a simple indicator of power status and should be ON solid during normal operation.
-
-- If the Red LED is Off, dim, or flickering: Test power input to VTX is stable at expected voltage and within input voltage tolerance of VTX.
-
-The Blue LED provides these status indications:
-
-- flicker 3x after boot indicates MSP signaling is detected.
-- OFF = camera lost (check camera and cabling)
-- ON/OFF @ 1hz = heat protection
-- ON/OFF @ 4hz = 0MW pitt mode active
-- ON/OFF @ 2hz = 0.1mw pitt mode active
-- Flashes quickly 2 times per second = RF chip(dm6300) failure
-- ON solid = VTX operation normal
-
-If both Red and Blue LEDS are on solid but no video signal is detected by VRX:
-
-- use spectrum analyzer (available on some analog VRXs) to verify VTX RF output on correct channel.
-- use a PAT version of firmware for your specific VTX to verify RF output from VTX and test patern signal is received by VRX.
-
-The test pads on the VTX can also help verify some segments of the VTX cricut. eg: pad labeled 1v8 should be approximately 1.8 Volts.
