tx works fine

Did you check under the couch cushions?

 

[Low_Boy]

tx works fine

JUST BECAUSE TX WORKS FINE DOES NOT MEAN THE BULB IS NOT BAD.

what Low boy is getting at is does the RX work on the radio? as he stated the bulb can burn out and RX will still work. read this 2 times and you do not say if the radio RX or not.

Did you test the old LED with a suitable power source? Maybe the LED is okay and your issue goes deeper..

 

[Low_Boy]

You still never checked if there was two points of power at the RX/TX bulb.

Yup check what feeds the LED, or the LED itself; let us know how you get on Kaos513.
