Question about 2000 Isuzu Trooper
This sounds like one of the most common problems with CD players(automotive or otherwise), a dirty or dust-covered lens on the laser head. To really get it back to good performance, the unit needs to be taken apart and the lens cleaned by hand. It is possible for an average guy to do, but if you have never done something like that, I must warn you: There are many ways for you to ruin the unit before you even get it apart. Once you do, the lens mechanism is extremely delicate(like your eyeball, really!) and can be misaligned by a single twitch if you are touching it. And, there is no guarantee that cleaning the lens will solve the problem-it could (also) be out of alignment from an impact or "sagging" lens suspension from age, or have slipping or missing belts(it may or may not have belts) on the disc select elevator. Listen for motor noises after the magazine is loaded. If it is a seperate changer unit, they usually have an inline fuse in the wiring behind it. But if all that seems OK, and it displays the disc and track number, but is "waiting" to start playing, you are probably better off replacing it, as servicing it at a shop will cost more than a new one, and there is no guarantee that it will be back to 100 percent even after that. I've been a pro sound engineer and service technician for 30 years and did plenty of auto sound systems as well along the way. CD changers are marvels of electro-mechanical engineering, which unfortunately makes them expensive to fix properly. Mp3 players are making them obsolete due to their mechanical simplicity (no moving parts) and relatively low cost to produce. That might be a better way to go. Good luck!
