Typical Jeep Stock Radio Problem Repair Options

"@alfa01,

I think if you pop one open you might be surprised at how easy to repair that generation of circuit boards are. Especially vehicle pcbs as they have to be ""rugged"".

The power caps and ICs are the likely culprits. Check the solder points underneath the pcb too (most pcbs of that era are through-hole). Look for the solder to be cracked away from the via. A crack will look like a clean ring around the entire joint.

Heres an example off the wiki: soldering

The other thing to look for is blown capacitors. The electrolytic will ooze out the bottom (the top if they're really bad) and you will see gunk around the base of the cap. The bigger they are, the more likely a suspect.

Also, take some pictures and maybe we can help to trace out the obvious circuits to help narrow things down.

"In the 21st century, repair men and ladies are gone to the way side, the labor prices make these small jobs not worth the effort, everybody is just replacing their units with new, used, aftermarket or trying simple repairs themselves as mentioned here, good luck.

You can clean with alcohol but once the CD laser lens is cleaned, wipe it again with a dry cloth as the alcohol will leave a residue, just clean it a second time with a dry cotton swab. Any adjustment for the laser strength will need the help of an oscilloscope to view the tell tale pattern at the proper strength. Dry or leaking CAPS are always a problem."

I just fixed mine. There were cold solder joints on the main board. I pulled the bottom cover off and re-soldered all the joints. Some silicone sealer had to be removed from the solder joint area in the process, but the radio now works.
