SC430 2007 Audio Amplifier

[Avril]

The amplifier in my SC430 has stopped working - any idea where to get another - desperate - thanks

hi

the LS430 amplifier has a common problem also whereby the power supply fails and the amp stops working - everything else works except no sound.

When mine packed up i got it repaired by svt services in edinburgh for £285 - they specialise in this sort of stuff

it might be an idea to give them a ring (speak to chris) and see if he can help you.

Yes agree with the above if it's definitely an amp fault and everything else has been checked. They do come up on auction sites from breakers etc but better to have it repaired if possible.

There are a few on eBay. One in the UK at £295 but a few others in the states on auction format so a bargain could be had.

Here is update on the situation re Avril Amp 'failure' - apologies it took so long but just got it back.

Amp was taken out of the car (radio showing on with channels and frequencies showing etc - SatNav shows only set up screen no other response),. Sent ot to SVT Services in Edinburgh - 'Chris' tested it on bench for 5 days and said it is in perfect working order, and returned it yesterday. Local Lexus blamed the Amp, but if its not the Amp ???

Has anyone any suggestions - and is the amp in some way part of the navigation system ie the audio perhaps or more intricately involved ie is partial apparent working of the navigation system a clue ?

 

Many thanks any help / Avril

I would take it to a good local car hifi shop and let them test it. If there is anything else that's causing the sound to be muted they should find it.

Thanks the reply. Today refitted (connected) the amp to system - i have all screens on radio and navigation working, radio showing channels, volume, frequencies, Navigation sign in screen etc etc - only thing is no sound. So now going back to Lexus see how they respond to statement its NOT AMP -  PLSE CHECK OUT RADIO etc

Did try a lot of radio fitting companies but they wont touch a lexus, and mostly only fit store bought radios in other cars - no diagnostics - all say business is too time consuming and costly - new radio is much cheaper option for most.

Let you know how it goes / Avril (thanks to all for replies)

That's disappointing, is there any sign of a car phone kit having been fitted to it, or any other work done on the car? I've read on the the US site Club Lexus that problems with speaker cables can sometimes have a 'no sound' effect. 

One more question, does the Sat Nav voice work?

Hi Everyone who followed / helped out. Finally have  a conclusion on this one - as previouslyadvised - not the cae -  the amplifier was not at fault (taken out tested and OK) . It was put back in the car and the local dealer had a SC430 in stock, changed the radio itself and bingo its working - so fault was in the radio itself. All now replaced with new unit and working fine.

I guess only message to take from this one is to have individual components checked if possible to confirm dealers diagnoses. On this cae I would have possibly ok'd a new Amplifier to find out that was not the problem - then what ???.

Many thanks everyones help and I highly recommend the company in Edinburgh - SVT SERVICES 9 speak to CHRIS) - first class absolutely top notch - breally nice people. You can trust them.

Excellent, good to hear the problem was traced in the end.
