Question about Electro Brand Vertical 3-CD Stereo Shelf System

5 Answers

Has power but controls won't work

A friend bought the above model (it was described as a memorex) but made in china. memorex model # vcd8bm/mo. they don't know anything, or even heard of it.
he droped it while trying to wall mount it. now, i still get power to the blue lites-except for the power/standby button. no lite and no function can't turn off or on. also, none of the other buttons work at all. no sound from radio or cd's. can't ajust clock, etc. and the right "saloon door" won't close properly. also won't work with remote-tho. maybe a separate problem.
please help.

    ser. # s/n 4800 mp3 007783

    power/standby lite doesn't work-the unit is in where i can''t even turn power to standby.

    all 3 cd lites on, no cd's work

    can't change radio stations etc. etc. etc. no buttons work

    if careful, can open cd doors, mech. does work. will get radio, but sometimes, when i carefully close doors, will get reading and cd will spin a little, then stops, will then tell me something the number of tracks and nothing else.

    guess that's about it.

    thanks

Hi,

In similar workloads/repair jobs, often the problem is either or a combination of:

  • loose connectors/wirings;
  • mechanical misalignment;
  • cold/loose solder;
  • cracked board, open foil underneath PCB (very often).
Corrective measures would involve opening the unit for a look and see. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Should you be considering a DIY, then initial diagnosis/checks would have to be done on the power supply. There should be a constant standby B+ (most likely +5VDC). Additionally, the mains B+ would either be triggered on through a relay or a switching regulator. Often, as earlier stated, cracked foil/trace on the PCB would be the culprit. This is component level repair and should be reasonably easy saved that it is time consuming.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

There is something wrong inside of the unit,caused when falling it down,try to check for the crack of the circuit board and misalignment of the mechanism of the CD player.Your unit now is in protection mode to prevent further circuit damage,that's why it will not turn off / on.Look for short circuit(accidentally joining its other parts when it fall) and if happens you see a breakage or crack try join it a wire jumper,if cracks solder joint,reworks the solder joints.

Hopes this may help;

Regards,

When the unit fell it might have moved the controls you might have to open it and have a look

Posted on Sep 11, 2008

  • chris07551 Sep 11, 2008

    what you should do is open it up and see if any thing inside came loose or undone any bits might have moved out of place

is this the unit in question?

Id almost just buy a new unit. by the sounds of it alot got shooken up in there and well your best bet would be to get someone to take alook at it that is familiar with the unit and able to take it apart and put it back together.

or open it up yourself and find out if you see what has happened inside. use a digital camera to take pics of where you got special screws ect from.

so you know what order to put them back in.

When the radio fell it may have popped the interior fuse or may have came out of the the holder... take the radio apart and look for the fuse. there may be more than one that would cause it to have power to only certain things and not the other

On my Philco Turntable CD with cassette the CD player does not close all the way. If you manually close it, it does not play


You are describing too problems, won't close all the way, could be a bad loadind belt. the second issue it will not play, the timing gear is out of sync, or the laser pickup is not functioning, you will need to take it to a service shop for assessment.

I got a Sony CMT-NEZ30 from a friend and I don't


Get the manual , which a simple search engine query for "sony CMT-NEZ30 remote" would have led immediately to...

http://esupport.sony.com/US/perl/model-documents.pl?mdl=CMTNEZ30

As far as remote failures go...

Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.

Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.

or check eBay: search for "(model of the device or the remote) remotes", check the 'include description' box. Usually cheaper than the vendors.

My Memorex MX4118 no longer has sound when CDs are played. The display shows the CD tracks and progress while "playing" but no sound. Used a cd lalser lens cleaner but still no sound.


If it's clocking time on the disc predictably don't mess with the laser.

http://www.retrevo.com/support/Memorex-MX4118-Radios-manual/id/1082dj096/t/2/

Is the CD indicator lit? See page 18.

Press the PLAY/PAUSE > '' / POWER ON button to select CD; the CD indicator will appear in
the display.

I have tried to record from Tape to CD with No result. I have followed the instructions for this task, to the letter and still nothing on CD.


Hi,
First make sure yoou are using correct cds. You need CDR Audio discs not blank pc media type (Yes they are different). Once you have the disc type right, make sure you are finalizing the disc as they will not play in other machines until u do this

I bought a Memorex MX3905 shelf system at big lots for 30.00 last August 2008. I had lcd display problems and exchanged for another one. As I exchanged it, this one had no lcd problems, but has amperfirer...


I work for Memorex tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your system needs to be repaired. However, I don't believe the internal parts for that model are available which means repair would not be an option. Memorex has moved toward replacing their electronics for customers with warranty claims rather than stocking parts for repair.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

I bought a used RV as well, and while the manual was not included, we were lucky enough to have the original "90 Day Limited Warranty Card", which provided a toll free number to the Customer Service Department. I called and a copy of the manual is in the mail to me today. 1-800-982-3954, ext 117. Good Luck!
