Just Had exact issue on my 2008. Stealership actually waranteed the DME, however I had already looked into repairing board. As for replacing components on a circuit board, do yourself a favor and get a decent soldering iron, and most importantly a push button "solder sucker" from radio shack. The RS employees will know what you are talking about. And don't be scared of the job. The vast majority of people out there would probably think that the job would be too complicated, but replacing components on a CB is actually pretty simple and straight forward.
*what you will need (typically)
- Replacement Parts
-Soldering Iron
-Solder (i prefer flux core for stuff like this)
- Solder Sucker
- Wet Sponge
- Dykes & small Needle Nose Pliers (depending on config)
-Good light
**Component Removal**
1. find component to be replaced.
2. Locate correct pins if they go through to the back side of CB.
3. Get solder sucker "cocked and ready"
4. Melt solder with soldering iron.
5. While soldering iron is in contact with solder keeping solder melted, put the tip of the solder sucker right down against the board over the pin or immediatly around the pin, and push the button that "fires" the sucker.
6. Repeat step 4 and 5 for all pins of component.
7. Gently remove component. (may need to remove more solder or just heat a pin or 2 while removing component)
**Component Installation**
*Steps 2 and 3 of installation should be done swiftly and carefully as to not heat the circuit board too much. If the Soldering Iron is left against the CB too long it can over heat the board and release the bond between the copper ring and the board itself. Don't let this scare you out of attempting this task, just be aware that if you leave the soldering iron against the copper ring for a few seconds and the new solder doesn't melt against it, then the iron is not hot enough, or the iron is too dirty. Iron can be cleaned up using a wet sponge. always good to have one handy anyways when soldering.
1. Place replacement component in original location. (pins may need to be bent or trimmed, depending how original component was installed. you be the judge.) However if the new component has long leads, and they are to be soldered to the backside of board. it is a good rule of thumb to leave the leads long until the component is soldered into place. Then trim off the leads as close to the new solder as possible.
2. Place hot soldering iron lightly against copper ring on CB for a few seconds. Gently touch solder to copper ring. Melted solder should very quickly fill hole and surround pin. (If not, clean iron, wait a few minutes and try again.)
3. Repeat step 2 for all component pins.
4. Trim leads if/as nessasary.
******DON'T GUILD THE LILY!!!!******** - Unless you are "ARE" a professional, YOU ARE NOT A PRO. If a solder point is good, but not PERFECT, do not ' attempt to make it perfect. Just because it does not look like factory does not men it's not effective. The more you mess with it, the more chances that you may burn the CB, or something else disastrous. You will regret it.
GOOD LUCK!!
