Accord Radio turns ON when the car is OFF 2005

This resistor is inside the radio, you must remove the CD drive to get to the PC board. The connector to the face plate is pretty fragile so take care to get it lined up when putting the face back together. Use a small soldering iron with a surface mount tip, tools are worth the $$$ to save the radio. Scrape the paint off the pc board adjacent to the resistor, get it hot enough to take the solder. After you're done soldering, clean with XYLOL or enamel reducer, alcohol is conductive and will leave a path between circuits, Lacquer thinner will eat the parts on the board.
What is the best soldering tool to use for this fix?

The soldering iron that I use is a Weller model WTCP with the small tip for surface mount like a PTR7. I believe the ETS or ETOB made by Apex will also work with this iron. There are many soldering irons that will work. The best are temperature controlled at 700 to 800 degrees F.

How did you get the circuit board out of the vehicle?
I have somewhat similar issue -- my speakers will be playing fine and them there will be a loud pop/thump and they'll go out -- and I'm pretty sure it's an electrical short of some kind.

As far as getting the circuit board out, you must pull the whole radio and the CD player out of the radio to get at it.

I finally found the culprit causing my 2005 Accord radio to come on when the car was OFF. A surface mount resistor was NOT soldered on the ground side.
See the attached picture, The dental pic is on the resistor next to D809. I had to scrape some paint from the ground to get it to take solder. This resistor is a pull down for the on/off logic. Drove me nuts, I traced every run from the power input through several resistors. This resistor moved when I tried to solder the side opposite to the ground. Radio has behaved normally ever since. Hope this helps someone, that radio is not only hard to find, it's expensive. Single disk CD player part number 39050-SDA-A020-M1. If the car was not used often, it would run down the battery.
