On the Ranger RCI-2950 will the display stop working if the internal battery gets old or flat. Mine comes on and works for a while then after about 20 mins a few legs of the display starts flashing on and off till they faded completely and after a while the display goes completely blank with only the side led lights on. I have removed all the boards and checked for dry joints and checked all the plugs and all seems fine...Anyone with the same problem ????

get hold of ranger and they should be able to help you.

have you tried it on all bands? still won't transmit?take it to a tech so they can fix it properly.

i have the same radio rci 2950. Ive had the same problem with mine,turns out with mine the processor would lock up,turning the radio off & on repeadly would clear the problem and the radio would work fine x-mit & recieve. the solution to fixing the problem is to replace the memory backup battery this battery works similar to a computer motherboard cmos battery when this battery goes dead all sorts of strange things happen to the radio wont transmit wont recieve or like your problem transmits continiously. the problem with replacing this battery is finding out what year & model your ranger 2950 is. the internet says only first generation ranger 2950s use the battery second genration & third generation do not use the battery. but the internet could be wrong. so i suggest getting a hold of (usa ranger.com) & give them a phone call or email and ask them about the year your radio was made. they may even service it for you or if you are electronic savvy you can do it yourself. the battery is located close to the main cpu on the front panel if yours uses a battery.

You either have a bad LCD display OR the connection for the LCD display is loose/off. Its impossible to tell what channel you are on with a 2950 without the screen working, but when you turn the channel knob do you hear any other cb transmitting on ANY channel?? This is a tough one!! I really need some more info on the radio.

Open the case and look at the area that the display is in (front of radio). Slightly wiggle all of the little plugs in that area. If you see the LCD screen come on or flash then you know where your problem lies. If not, then you're probably looking at buying a LCD display for the radio.

Good luck.

could be a number of different problems causing this. I would start with your microphone make sure it is working. it is responsible for transmit & recieve. next check to see if the memory battery is dead this will also cause this problem. next check the regulators in the radio to see if they are supplying voltage.next check voltages in different parts of radio to see if all stages are recieving power follow these steps and something will show up also check your switching diodes to see if they are bad the diodes responsible for x-mit & r-mit of transceiver.

check the ground wires

Bad mic? dirty mic pins? If the mic is bad, you will have no receive.

Hello, Just offhand I'd say you have a bad solder joint on the main circuit board. Without more info, I can not tell you where to look,,,,, Mechanic
