Troubleshooting:
First
check to see if the unit turns on at all.If no lights come on ,check
the AC power cord and the outlet it is plugged into.If these are
ok,check to see if there is an external fuse on the back of the unit.If
not, DO NOT OPEN the case as dangerous voltages are present inside the
set.The internal power supply may be burnt out ,so send the unit in for
service.If the unit lights up but you get no sound ,look to see if the
speaker selector is switched to the speaker output you are
using.Next,check that you do not have any switch such as "tape", "tape
monitor" , "ext source, eq,processor,or loop" depressed or
activated.Sometimes a small indicator light or symbol will be seen on
the display. Next, see if any warning light comes on such as
"protection" comes on and stays on when the power is applied.Most units
have a protection relay that clicks on a few seconds after the unit is
powered up. If you do not hear this click or the protect indicator
stays on , there is a good chance the output stage is shorted in the
unit.Also check that the speaker wires have not been pulled out of the
rear of the unit or out of the speakers.
Static,noise
and loss of signal can be caused by loose or defective
cables .move the RCA cables with the volume turned low and see if you
get static or signal dropout. If you do try cleaning the jacks on the
rear of the unit or replace the defective cables.If you have static
when you move controls and switches they may have to be cleaned.This is
usually a minor repair.
If the
CD does not play and the player lights up, check that the cd is
inserted correctly. Most CD players require the label to be facing up,
but some are just the reverse. check your owners manual. If the CD
loads but does not play you may have: 1, a dirty disc, 2; dust on the
lens of the laser pickup, 3; a defective pickup. First check your disc
and if it is scratched or has fingerprints on it, replace or clean the
disc. Consider the environment the player is in. If you smoke in the
room it is in, the lens will pick up a film of smoke particles and fail
to read the disc. The same thing can happen if any source of fine smoke
or dust is present. Sanding dust from home improvement projects,
fireplace dust and cooking smoke can do the same thing. If the unit is
in a bedroom, powdered makeup, dusting powder and spray products such
as hairspray and deodorants can fog up a CD lens very quickly. If you
suspect a dirty lens DO NOT WASTE YOUR MONEY ON SO CALLED "CD LENS
CLEANERS". NONE OF THEM WORK WELL, AND MOST DO NOTHING AT ALL.
Considering the low cost of having the lens cleaned it does not pay to
try to clean the lens yourself. CD pickups are expensive and can be
damaged very easily. If the drawer of the cd does not close all the
way, the load belt may be stretched out or worn. This also is not an
expensive repair in most cases.
