ive seen this problem before with these silly cd players, ive worked on quite a few as a company i used to work for had an account with alrenco, anyway, problem was that the ribbon cables would start to go bad after taking these things aparts so many times, there was a certain procedure i had developed for tearing these things down, if i remember right the easiest way to put them together was to turn the thing upside down first, then insert the cd bottom half while holding the cd door open, it just slid everything better that way. seems like there was also a problem with muting transistors in these on the audio lines, but i dont remember for sure. but just check with scope, follow from the d/a converter > selector ic > power amp board. >From: "Jim Myers" <jr.myers@xxxxxxxxxxx> >Reply-To: techassist@xxxxxxxxxxxxx >To: <techassist@xxxxxxxxxxxxx> >Subject: [TechAssist] Re: Audio Fisher TAD993--CD problems >Date: Wed, 5 Sep 2001 10:08:57 -0500 > > >I had similar problems with same model after making sure the assembly and >alignment was correct, I found that the lever on the front panel that opens >the cd slot door was out of place.
