Cobra 75 WX ST powers on but does not work

This is a new CB I installed recently. When I power it up the back light comes on and that's it, display is blank. I have the same CB setup in another vehicle so I tried the hand unit there and it worked fine. I had another remote connector box handy so I swapped it in place of the one that I thought was not working. Same problem. There are only three connections here, power/ground/antenna. It powers on so the ground and power should be good but I cant see any reason the antenna would cause the CB not to initialize.
Any help would be appreciated.
Thanks

Problem fixed. I only had 11.59v where I had tapped in. Ran power from battery and everything works fine now.

MAKE SURE THE ANTENNA IS NOT CONNECTED, THEN TRY AND SEE IF RADIO POWERS UP, IF IT DOES NOT THEN YOU DO NOT HAVE PROPER GROUND
ALSO ARE YOU USING THE COBRA STOCK MIC ?
ALSO MAKE SURE THE RADIO IS ON CB MODE NOT WEATHER MODE

I get no squelch on my cobra 75 wx. I can't receive when somone transmits near me.

that's normal . If someone near you has more power then you he will walk all over your signal . You just might be doing the same to them.

Cobra 75 wx st fuse keeps blowing. As soon as I plug the transceiver into the connector box the fuse blows.

Hi and welcome to FixYa,

Initially, check the reverse protection diode, D18 (1N4004). It would be located / connected at the power board of the DC connector.

Good luck and thank you for asking FixYa.

Cobra 75 wx st everything seems to work eccept receiving signal meter will spike on trx and it seems to receive but no sound there is sound in wx mode

WX is for weather. If you put it on WX, and you do not hear anything, then you need to change the weather station it is on. in wx mode, you change weather channels by pressing channel up and down. To communicate with 2 way, press the cb/wx button so it is on CB mode.

Cobra 75 wx st

Hi and welcome to FixYa,

Initially, pls a couple of ideas you may want to consider/explore or try/check:

PA/CB switch must be to CB;
RF Gain max clockwise;
Squelch counter clockwise;
Volume to your desired level;
Mute (off);
external speaker/speaker connection;
audio amp, verify if there is TX modulation;
antenna, antenna cable. SWR should be low.

Good luck and Thank you for using FixYa. Happy New Year.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate this at all. Cheers.
