This is an excellent system for a bedroom or small office area. The random color changing light feature is very soothing to fall asleep to as well as the random/all disc playback so you don't fall asleep to the same thing every night! The 90 minute max sleep timer is just perfect to give me time to read a little and still be able to fall asleep to music. I also use the random playback feature during the day to play my parrot's training CDs so he doesn't get bored either! This is a great system and I highly recommend it.

Emerson has the manuals for many of their products here: http://www.emersonradio.com/owner_manuals.php . Use the drop down menu to select the model. The direct link to the manual for the MS3105 is here: http://www.emersonradio.com/resources/owner_manuals/manual_1312901899.pdf .

I hope this helps.

kungfuz...I have had two of these emerson cd players. One is in my home and is still working after 3 1/2 years. The other was purchased for our church just over a year ago and it has stopped working. The disks will turn a little then stop. Occasionally it will still play a complete hymn but this is rare. Also a grinding sound can be heard with the ear close to the unit. I think when you pushed the combo of buttons and it stopped working, this is likely just a fluke and it was probably going bad anyway. I may be wrong but I have been down this road myself and your problem sounds very similar to mine. I can't offer you much encouragement...sorry...!

How often was the player used? Four years is a typical lifespan of a cheap CD player section if it sees constant use, and on this specific model i ran across a few cases in which the system died after a few months, and it makes you wonder why the warranty is only for 90 days(the ones i saw)... First, let's see if the player tries to read the disc. Load a disc and listen. Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable. Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word. This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces. You could try to clean the optics. It would involve taking the cover off and finding a way to take a slightly damped swab and gently rub the objective lens on the pickup clean, followed by a drying with the dry side. But, unless the player is prone to dust accumulation (which was a big problem with quite a few Aiwa shelf systems with the 3 disc changers), cleaning it may not help. Another possibility could be that the transmission ribbon which connects the pickup to the player electronics may have developed breaks, which is another typical problem with many shelf systems. Yet another possibility, which is the worst case: the pickup may have worn out. Again, if the player is four years old and was used constantly, it is very possible that the pickup has decided to give up the ghost. Another possibility, which is EXTREME worst case and is not likely to happen at any time with any CD player is a failure of the CD decoder chip. The decoder chip handles the 8-14 demodulation and error correction of the CD signal and outputs the processed signal as PCM for upsampling and conversion. If this chip fails, the CD player will spin up and synch to the disc but, without decoding, the player will be unable to read the TOC and play the disc. But, as I said before, this usually never happens as the semiconductor parts are the most reliable components in a CD player and usually never fail unless they were deliberately damaged by an external influence, like shorting out one or more leads with a screwdriver while the player is powered. In the latter three events, replacement parts may not be easily sourced, if at all, and the required labor to effect the repair may not be worth it. (In addition, a new pickup has a protective solder short designed to protect the laser pickup from static discharge damage. This short has to be desoldered in order to allow the pickup to function.) In this case, replacement of the entire shelf system becomes necessary. If buying a new shelf system, stick with some of the better brands in this area like JVC, Sony, Panasonic, Aiwa, Pioneer, and even Philips. Brands to avoid include Sharp, Sanyo/Fisher, RCA, Emerson, and any cheap store brands like Durabrand or CurtisMathes. But, in general, even the finest shelf systems are a compromise in design which can affect reliability. Most, even from the recommended brands, weren't designed to be serviced very easily when they break as people usually dispose of them rather than have them repaired.
