Question about Sony MHC-GX470 Shelf System
I have a Sony HCD-GX470 3-disk shelf system..
When I play a CD, I will hear a click sound after a few seconds of play, which continues and it will make my CD skip repeatedly...
I'm beginning to think these mini CD players are a waste of money because they quit functioning properly after less than a year...I really don't wanna have to buy another one, so I'd appreciate a solution to my problem. Thanks

I think grooves are dirty / clogged in sled section of lens mechanism. There is flexible wire between lens and circuit board and this should also be checked as it can be cracked or misaligned.
Below is exploded view of lens in MHC-GX470 and marked area to be checked or cleaned.

Hi There are many things that can cause your problem, I can tell you the most likely ones, but I recommend you don't take the unit apart, as the mech. in a 300 disk changer is complicated & delicate, and you may just cost yourself alot more money than getting it repaired. The symptoms you sescribe can be caused by failing laser pickup, dirty laser lense (especially if you've done home renvations with drywall), split drive gear that moves the laser on the sled rails, or even a hair or piece of dirt in the gear teeth of that same gear. The unit will play fine, until it hits the tooth where the debris are, then it skips, or jumps back a bit and starts again until it hits the same spot. Also..badly scratched or finger printed disks will cause that, but that is the first thing most people check. I wish it was something you could repair yourself, but my best advise is to take it to a reputable repair shop, and hope it is not a bad laser, as that is a fairly expensive repair. Hope this helps, Good Luck!

Try using a laser lens cleaner. I have the Maxell Thunderon one thats on a Gold CD that you can get at best buy for like $20 or so, seems to work good here on the computer disc drives

Try cleaning the lens. If you can see the lens when you open it to put a cd in, you can clean the lens yourself with a q-tip. Use a very small amount of alcohol or windex, just enough to make the tip of the q-tip moist, and rub it on the glass lens in a circular motion. then use the dry end of the q-tip to dry it off. You can then try another cd and see if it plays good. If so, you are good to go, if not, you probably need a new laser pick up. If it needs a new laser, you may want to just buy a new boombox. The repair will most likely cost as much or more than a new boombox would.
If you are not able to see the lens and clean it yourself, try using a cleaning disc. They do not work as good, but they can help. You run it for about 20 seconds, or whatever the directions state. Then give it another try, see if it plays better.
Those are the only reasonable steps for an end user who is not experienced with repairing these type of units. anything else you may end up trying could just cause more damage to the unit, if you are not experienced with electronic repairs.
I hope this helps, let me know if you need more help.

all the rca's have been released without quality control... you will have to open and adjust the potentiometers (the adjustible resistors on the main board) to re-calibrate the laser timings. However the way that the boards are mounted inside the boombox's chassis you will need to take apart everything to be able to reach the main board (inside vertical right side board with large heatsink and fan) without causing a short (as to be able to properly adjust these you need to have a cd playing and the whole thing needs to be upright.
I would recommend throwing it all way, not worth the time if you don't have the patience.
