TRX-2: Radio Only Runs With USB

[k1jbp]

I have a TRX-2 that I got for Christmas. Last night I went to turn the scanner on, and it wouldn't start up. Figuring something was wrong with the wiring in my truck, I brought it in the house. By chance one of the suggestions was to upgrade the firmware because it might of gotten corrupted. When I did that, it came to life. Problem is now that it will only turn on if the USB cord is plugged in. I did try reinstalling the firmware, but it did not cure the problem.

The USB cable will power the control head and it will work regardless of the main radio unit. You could have a problem with the connectors between front panel and main unit. Hold in the lock button and pull off the front panel and inspect the connectors. Perhaps the only thing needed are to "exercise" the connectors to get rid of any oxidation that could easily happen in a car.

THe scanner is not even a month old. Taking the power cord off just freezes the display.

Try this:
· Unplug power cord from back of scanner
· Unplug USB cable from front of scanner
· Detach removable head
· Remove and then reinsert SD card
· Reattach scanner head
· Press and hold power button for 30 seconds (leave cables unplugged)
· Release power button
· Plug in power cord
· Press and hold power button until screen shows “Power on, release button”

I did as instructed. Held power button for 2 minutes to turn back on but still nothing.

Then reach out to Whistler or exchange it for a new unit if it is less than a month old.

I will have to contact them then. Looks like no one has run into the particular problem before.

If you Google TRX2 power issues you'll see plenty of threads about powering on issues.

Yes, I have done that. All say to disconnect everything, take the sd card out, and hold the power buttons for various amounts of time. But it is still unresponsive when holding the button for a second time to power back up.

Just a few questions when hooking up the scanner in your truck
RED to positive
BLACK to negative
Take a VOLTMETER and read to truck voltage motor off then read the voltage motor running.
Did the scanner turn off when you started the truck.

My TRX-2 would not power on. I had it in my vehicle at the time. I brought it in the house, and hooked up the A/C adapter. It would still power on. Someone recommended reinstalling the firmware. The scanner powered up when I hooked up the USB cable. I did redo the firmware, but it didn't resolve the problem. MY scanner will only work if I leave the USB cord plugged in. Do you have a solution, where I can restore normal operation to it?
