When the issue happens, dose the radio display stay on….
I would pull the radio and check the connection plugs….
The radio display stays lit/on? If you put a cd in (if equipped)
does the sound play? Check in your trunk that nothing is hitting
the speakers or the wires are not together. Either a speaker is shorting
causing the amp circuit to overload or the amp itself is a problem.
You could try and unplug a speaker at a time and see if sound returns.If fiddling with it doesn’t resolve the problem, pull the radio and take it to the dealership. They will ship it off to a repair shop. When it returns expect to pay between 100 and 200 dollars.
radio display is functioning. volume intensity is showing but no sound. This happen three weeks ago. Last week the sound came back. Now no sound.

My 2006 Accord does not have sound and the light is on. I heard pop sound and sound went out when this happened a few months ago. Now, it does not “pop” any more – just not sound.If you repaired digitizer circuit on your radio, please share how you repaired it. Thanks
The radio and the climate controls are in one unit. There are two circuit boards:
– The one, mounted vertically, is for the display panel, volume control and climate control knobs.
– The head unit is mounted perpendicular to the vertical display unit. I open the head unit. Removed the heat sink thermal paste and re-applied a new coat of Arctic MX-4. The sound came back for couple of days. I may have touched something on the display/climate control board to make it worked for couple of days.I will take the unit out again and examine the display/climate control board. If I don’t see any visual sign of burnt components, I will use my hot air repair station to re-flow all solder joints on that board.
Another source of the problem is the connector between the radio unit and the display/climate control board. That is it – the connector is the problem. When I worked on the radio unit to replace the thermal paste, I separate the radio unit from the display/climate control board. It worked for 2 days after re-seating these two units. I will take a closer look at the connector on both unit.
But anyone have the fix for the 2006 Accord radio “pop” and no sound issue. Please let me know. Your help will be appreciated.
I took the head unit(HU) out yeaterday. Disconnected the connectors. From the connector, I measured the resistance from the connector to the each speaker. I got about 3 ohms for all speakers. I also tested for shorts from the speaker wires to ground. All speaker wires are fine without any short to ground. Therefore, the popping noise is not due to speaker wire shorting to ground OR speaker internal short.
I think the problem is inside the HU. I disassemble the HU and put it back together without re-flowing any solder joints. Same as last time, my radio is working again by disassembling and reassembling.
I used the FADE function to disable the both FRONT speakers. ATM, my radio is driving only the REAR speakers. My radio has been working for 1 day driving only the REAR speakers. This is my way to troubleshoot which part of the internal circuit has the problem. Stay tune for more updates.
