Hi-fi Problem 1994 Celsior

[steve2006]

Hi,

Strange one this I have lost the sound from my front right speaker, if you turn up the volume and use the fader/balance buttons to feed only this speaker a hiss is heard suggesting output is ok with the audio at a low level in the background.

I've read up on other similar problems which suggest the telephone mute circuit but does this affect all the speakers or just this one and the 94 models?

Additionally even though I have some wiring diagrams none seem to match up to my system.

Any advice welcomed,

Thanks,

Steve

Here are some photos of my system including the boot mount kit

Thanks Andy,

I wasn't sure as it related to the 90-92 model but will do this tomorrow by the way I had a quick look tonight and from what I've read about removal of rear seat there should be two tags at the front of the base which you pull to release the locking device ( another site suggested a crowbar!!!! what on a Lexus!) could you confirm please and is the connector under the seat base or back part?.

Cheers,

Steve

No crowbar needed,pull the base of the seat upwards and it should release.

The connectors are under the base disconnect them and spray/clean with wd40.

Ther is a link under recent post started by tom hadfield which has a link about the problem although the picture is not an ls the principle is the same.

I had this problem on a 92 I owned but think it is related to mk1 and mk2.

Hi,

Seat came out quite easily cleaned and sprayed the connectors but no improvement.

I have now located and purchased a service manual for the Pioneer hi-fi system model CDX-M8036zt so should be able to diagnose and sort problem will update later.

I will also make this manual available to forum members on request.
