Did you maybe cross the wires somehow and pop the reverse polarity diode ? If you open the radio ,stick your nose down by the power input and take a good sniff you may smell something burnt,electrically. If you do then get a flashlight and look at the only diode that is near the power input wires ,if it looks burnt ,change it with the same diode but new. Make sure the banded end goes in the direction of the arrow .

This has an LED channel display, which is the same as the Cobra 29. You can pick up a new one, there are a few color options available. You need to be very proficient with de-soldering and soldering small parts. You need a desoldering iron or desoldering wic, and no bigger than a 30 watt sodlering iron, any bigger can burn the foil trace, and some solder. You have to open the case, remove the faceplate screws, remove the faceplate, remove the channel selector/pcboard, and the channel display pc board together. Now you desolder the pins of the display, aproximately 20, remove the diplay, insert the new display observing direction (make sure it is face with the decimal to the right place), solder each pin to the pc board, and clip off the excess section of the pins (which is sticking out of the back of the channel display pc board. If you have changed to a blue display, you need to remove the orange or green cover, and replace it with a blue one (I make mine from blue transparant report covers) and hot glue it to the inside of the faceplate where the old one would have been. The reason for this is that the blue light will not shing blue thourgh a green or orange cover, and if you use clear, the display will be extremely bright, and the blue cover will knock down the glare a little. Now just put the radio back together and fire it up.

Now with that said, if you think you may have any trouble with this, you can take it to any cb shop and they should be able to help you.

Any more questions, don't hesitate to email me at [email protected]

The RK56 was a good mike until Telex bought out Turner many years ago. Now the audio output is lower than it used to be & it's not a compatibility issue as Galaxy radios have microphone amplifier circuits similar to most other CB & 10-Meter radios. You'd have been better off buying an Astatic 636L or even a generic noise-cancelling mike instead. The only thing I can recommend is to hold the mike on your cheek, close to but not directly in front of your mouth, with the grille facing it & speak in a louder than usual voice.

SOURCE: no power to ignition

Check your ignition switch,it could be separating and not allowing voltage to go to the accessories

I hope you have the right equipment to work on this. http://www.cbtricks.com/radios/galaxy/dx99v/
If it was modded you may be in for a long haul. There are a lot of youtube vids on how to mod radios and not many of them do it correctly. Good luck

Is there a diode inside a galaxy dx99v that could be blown and not letting it turn on ?

Yes there are diodes in the power supply, but it could be a fuse, resistor fuse, or a bad switch, a host of things. You need to take it to a tech unless you have schematics an a good VOM.

TURN DOWN THE DEAD KEY ON A GALAXY DX99V

you must have a watt meter to do this correctly. turn vr 16 which is your low power and vr13 which is your high power.Adjust these to bring down your DK and vr 14 to bring up your modulation. if you want it lower you have to get into the radio and if you don't have the proper equipment you cannot do it , also you must be a qualified tech to go much further.

No transmit on a galaxy dx99v

Meter.......... oh that was to little effort.
Check the mic a broken wires/solder connection in the cord are often the most common problems. Bad mic switch?
If no luck with that pull speaker side bottom cover. Notice on back end inside of radio 3 square, black, 3 legged transistors. Which mounted to case they should not be cracked or discolored. The far left one is a predriver this would stop all tx the other 2 are finals which would just degrade power. After checking this check resistors for discoloration. A cold solder joint can act as a open connection notice the color of the solder on the other side of board a dull color to the solder is a indicator. If you suspect a cold solder press down with care and a nonmetallic tool in that area with power on and radio keyed while watching meter.
Finals can and do fail when over stressed by power modifications make to these 40 watt radios.


Although you have a aging rig Jul-2006 Stopped Production that has electrolytic capacitors that dry and leak these units can be very durable if they have not sat unpowered for long periods.
Hope this helps

Frequency counter displays two digets high from hump on fine clarifier adjestment on usb.27.186 insted of 27.185. also in am mode shows dead on with clarifer hump until mic is keyed thin dropes from 27.185...

Turn that fine clarifier a 1/4 turn or so to the right. I own a Galaxy DX99V and sometimes if that clarifier is just right it will drop down a hundredth of a MHz just like that when the mic is keyed. Your radio is just fine. Just adjust that clarifier a tad. The Galaxy DX99V is one of the best radios out there. I love them. -73-

I have a Galaxy 99 and I just swapped companies and I now drive a Peterbilt 387. When I plugged my CB in it tripped the fuse. I replaced the fuse behind the glovebox and CB still doesn't work so I am...

The Galaxy DX959 radio requires 12volt DC power. There should be a plastic fuseholder in the power cable near the radio end. There are no fuses inside the radio.
Ascertain that the radio has been connected up with the positive and negative the correct way around before replacing the fuse. Do not bypass the fuseholder or use a fuse with a rating larger than the origianal fuse.

If you have connected the radio to 24volt truck power instead of 12volt power even once you will probably need to send the radio to a competent technician for repair or buy a new radio.
