Re: will freeze up
You could have taken back your set to the supplier since it was under warranty then now it is too late.you will have to pay for repairs of your set.take your set to a tech the problem is in the power circuit more or less a cap is defected there.good luck.

I guess you answered the question right then....., you need the antenna. If you've lost the antenna, I'd suggest a piece of wire, not too thick though... As for the AM, that uses a loop antenna, so you might have difficulties with that one.
These are rare model with a limited service support and it is important that you need to get this part ONLY if the failed unit has a universal replacement which must be checked physically with any electronic showroom. If this is not properly confirmed please do not spend any more money on it as a replacement also can be short lived if the quality of spare is poor.
Hey...if your system is less than a year old it may be covered by the warranty, if not remove the cover to access the inside of unit. Near the power supply inside there is a fuse, it may be blown.
Can be found at local electronics supply.
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...!
I bet your unit is about 4 years old... I have installed 4 of these systems 4 years ago and each is failing at about the 4 year mark (3 so far).
The flashing volume lights are a communication error, meaning the keypads are not communicating with the controller. If all of the keypads are doing the same thing and your have checked your cables then the problem is with the controller. I would unplug the unit for a few days and see if that helps.
It appears the units work consistently and reliably for about 4 years however in my case 75% have failed at the 4 year mark.
Fortunately I have a meter and oscilloscope and determined why they are failing. The main power supply unit that feed power to the 5VDC regulator is failing.
It is not clear whether M&S replacement units have addressed this problem or not. Therefore, to fix the problem for my customers, I added and additional small power supply (fits inside the case) and injected the signal on the input side of the 5VDC regulator. My solution hopefully will not expire after 4 years.
It appears to me from my small sample size that M&S may have a flaw in their original engineering and replacing it with the same will guarantee future failure.
Unfortunately, these older systems lose value rapidly and the cost of repairing problems like this can end up being as much as buying another system! Actually, you might be surprised to learn that JVC Service still sells many accessories and components from older systems. You can buy this sub woofer for less than $100, which should easily beat any repair cost you'll face. It may even come with the satellite speakers. The part number is VSDT2000R-SPBOX .
NOTE: JVC Service has a free shipping coupon going on right now, so you'd want to use that: DZYZXFX49GYZZ81
Also remember that there's a standard connection between the head unit and OEM sub woofer, so you're free to use a non-JVC unit. I would try to find one with a comparable power rating. Of course, the only drawback is that it won't blend in with the unit... but then, the sub woofer is usually tucked away out of sight.
did you ever get a solution to your problem ? I have the same problem, I called Customer service and they wanted me to reset the unit by just unplugging it for 40 seconds (and holding down the power button while it was unplugged) which didnt seem like a way to reset it to me, since all of my radio presets were still there. it did it again yesterday, the volume all the way up. The Cust Svc person (who im sure is not a tech) said she had never heard of this problem and said I could send it in for service for $69 plus parts. (not worth it.) email me back if you found out a better solution, i just found the resetting by unplugging didnt work for me. jen21090 @ yahoo . com
Yeppers, when you where changing out those speakers, you shorted them and that in turn blew out the audio output IC inside this unit. This will require you to disassemble the unit, locate the blow output IC abd unsolder it, get a new audio output IC, put some heatsink compound on the back of the new IC, resolder the chip and reasassemble the unit. But before you turn on the unit, double check those speaker wires again to make sure they are not shorted as if they are, even one tiny strand, this unit will blow the IC again. Never work the speaker on any solid state electronic amp when they are plugged in and on. Good Luck
