turn the squelch down? the RF gain down too do you have an attenuator turned on ?

There is normally an electrolytic capacitor on the back of the display that regulates voltage for brightness. Sometimes thy are easy to replace. Or give it to a radio engineer, or return it to Icom for repair. They would likely just replace the display module and board. Someone else reports low contrast. https://forums.radioreference.com/threads/ic-a24-screen-contrast.321716/ https://www.google.com/search?q=ICOM+IC-a24+blank+display ..

It can be a few things but first try resetting your CPU, while your transceiver is off, hold down the UP & DOWN buttons simultaneously then turn the transceiver back on, now it should be reset to the factory default settings

The RX light should light up when receiving a signal. It may be your squelch setting is too high. Push the VOL knob until it enters the squelch setting, then set the squelch so it just cancels noise. If still not working you could have a wire broken in connector from headset that plugs into the radio.

Send it in for repair. It is broken https://www.google.com/search?q=Icom+ic-210e

If you're hearing a beep when pressing a button on the remote keypad for your IC-7610, it's possible that the keypad is not programmed correctly or is not communicating with the radio properly. Here are a few troubleshooting steps you can try:

1. Check the connection: Make sure the remote keypad is securely connected to the radio's remote jack using the supplied cable.
2. Check the settings: Make sure the remote keypad settings on the radio are configured correctly. Press the MENU button on the radio, select "Set" and then "Remote Operation." Check that the "Remote Type" setting is set to "IC-7610" and that the "Remote Address" matches the keypad's address.
3. Check the keypad programming: Make sure the buttons on the keypad are programmed with the correct commands. You can check this by pressing the MENU button on the radio, selecting "Set" and then "Function Keys." The functions assigned to each key should be displayed on the screen. If they are not, you can program them by pressing and holding the F key on the keypad and then pressing the button you want to assign a function to.
4. Reset the radio and keypad: Try resetting the radio and keypad to their factory settings. You can do this by pressing and holding the POWER button on the radio until it turns off, and then pressing and holding the FUNC button and the ENT button on the keypad while turning the radio back on.

If none of these steps work, it's possible that there is a hardware issue with either the radio or the keypad. You may want to contact the manufacturer's customer support for further assistance.

The Fix Programming via CS-R6 with Windows 10 made the problem. Scanning was very slow. The CS-R6 program through Windows 10 made problems with the scanning speed - it became very slow, one frequency in 2 seconds instead of 100 frequencies in one second. Through programming CS-R6 on Windows 7, the scanning speed returned to the corresponding one in the ICOM instructions - 100 frequencies per second

Hi, please move the radio away from it's current position to attempt to find alternative position where it's frequency will be transmitted clearly as intended. Also, please keep away from any microwaves or speakers so as not to cause any interference. Thank you.

There are a few possible reasons why your radio might not be transmitting in CW mode. One possibility is that the keyer chip has gone bad. Another possibility is that there is a problem with the power supply. If you have a multimeter, you can check the voltages to see if they are within specification. Finally, it's also possible that there is something wrong with the antenna connection. Make sure that everything is securely connected and that there are no loose wires. I hope this helps!

Hi om sounds like you may have a break or something making that ant go haywire, have you checked all the line to see if there may be connection problem.another thing could you try the ant direct with a matcher inbetween to eliminate the auto tuner from circiut. This would narrow the fault down, have fun

Contact Icom to inquire.

Look at pages 16 to 20 in the user manual. This may give you some insight as to haw this may occur. Also, A google search for this radio brings up a lot of useful info. This is a complicated radio as is indicated by the 80 page user manual. It's not one that you can pick up and use right out of the box!

The link below should help you. Lots of info in the service manual. It's intended to let someone rebuild the radio from the ground up.

Try using an external speaker and see if you have the correct volume level. Radio speakers fail often, especially when used at high volume. The simple fix is to replace the speaker. It is seldom for the audio amplifier to fail this way. Usually they work or they don't.

Try adjusting your RF gain control. This will often cause this to happen if it is fully on.

Here's a link to the service manual - www.shercoares.org > doc_files > manuals > ica110_sm. This may help. Have you checked both fuses? They should both be about 10A. Use a meter to check them. A visible check may not show the fuses open.
