I realize this thread is a little old but I just signed up because I purchased a 2006 Accord for my sons first car. It’s a Value Package 5 speed manual. The radio is model 39050-SDA-A110-M1 but the board looks identical to OP. The problem is the backlights don’t work and no sound. I experienced the radio flickering on and off one time with the key out but we’ve only owned it a week. I was excited to find this fix because all of the other threads on here and the Drive Honda forum seem to be about the failed resistor/fuse from a different board that apparently comes with the CD changer model with a ribbon cord. When we bought the car we knew the radio didn’t work but didn’t know the backlights didn’t work until we drove it at night. So I need to fix this and I’m a little more anxious now that I’ve seen the flickering with the key out. It took me a little while to figure out the screws holding the CD player in (you have to remove the plastic shroud). But once I got it out it was identical to OP’s so I thought I would give his fix a try. You can’t appreciate how small this resistor is until you try to solder it. I used a magnifying glass with reading glasses but still had a hard time getting the solder on each end. Maybe I’m not very good at soldering because I melted my wife’s plastic stand a little that holds the magnifying glass because I was laser-focused on the task. Anyway, I did the best I could and even replaced the heat sink compound as mentioned in another thread. Someone in another thread mentioned cleaning the board with alcohol but it appears to me that the blue film on parts of the board was from the factory so I didn’t do that. I replaced everything and had a somewhat difficult time getting the case to snap back into the front panel but it seemed like it pooped in OK. However, no difference after the repair. I’m kinda bummed because I don’t see anywhere else to turn now except to replace the unit. It didn’t flash on/off with the key out but I am worried that it may do it again and run down the battery. I am probably going to go aftermarket as I fear going OEM it may just be a matter of time before it happens again. Aftermarket isn’t ideal either but I feel more confident about it long term. Probably either the Metra 99-7803G or the Seicane H619K. Can’t go with the less expensive under-compartment option because that still keeps the factory radio controlling the climate controls which is the major problem. None of the options are inexpensive. If anyone knows of other reasonably-priced options please let me know.
