Hello, I've been lurking the site for awhile but just made this account to ask for help. I have a Mitsubishi CD/cassette/radio (model P04704383AE, circa 1998) recently bought off of eBay. It works just great - following Jeremy Schrag's guide, I cleaned all the buttons & sliders on the face PCB, which eliminated dirtiness & flickering lights in the EQ and fader, so it works even better. However, the CD player still refuses to play modern CD-Rs. I tried the 1/16th turns clockwise and counterclockwise on the laser power pot, without any success (with the CD port facing right, looking in through the side as pictured in Schrag's guide). Actually, going clockwise even 1/16th resulted in being unable to play CD-Rs or CDs both. I can't actually get in there enough to see the laser lens and tell if it's dirty; I only know that it will reliably play commercial CDs only. Could it just be a matter of having a dirty lens? It's worth noting that my particular radio's face PCB was held on with two screws, and thus is a little different than the one in the guide. But still - a laser power pot is a laser power pot, right? Going further, would be possible to swap-out the CD module in my unit with the CD module in a newer Mitsubishi radio (maybe one of the RAZ models)? If such a swap could happen, would it be very likely to solve the issue, or are those slightly-newer units just as picky about copied media? If the swap can't happen, are there any other practical ways to modernize the CD module? Seems like I remember reading about some company which offered modern radios packaged in vintage-like bodies. That would be very cool, if the price is right. Any help here would be much appreciated. I know I can just slap an aftermarket radio in there and it would work great, but in a perfect world, I'll get to keep my CD-R functionality AND have an OEM look in the dashboard. I already have mods in place for the amplifier remote-on and aux-in for MP3 players (in the form of a low-power relay and wired FM modulator). He'p me, Mr. Schrag! He'p me! Also, sorry about the insane wall of text up there.
