2003 Accord radio LEDs
 

The LED's behind the six preset buttons are out. Does anyone know how to replace them?
Thanks,
Ron

the LED's would not all go out at once. likely a loose solder connection at an LED or the drop resistor. if you are handy with soldering SMD devices (they are TINY) - fully disassemble the radio to inspect. i would start by re-soldering each LED lead and the resistor lead. that will likely solve the issue.

note that the surface mount device (SMD) LED's are cheap, but the actual task of soldering them is quite a feat.

this is a representative pic of SMD LED's in an aftermarket head unit:

LED's are wired in series in groups, then a drop resistor sets the current through them. a single lead in the chain can take out the group. solder joints fail. hopefully it's that and not the actual LED driver/controller IC.
