Hi everyone,
Just found a MX 3000 put out as trash on the street. Perfect condition - except that the sound does not work. The on screen display tells me that the sound is turned up, but there is just no sound coming out. Any ideas of how this could potentially be fixed? I think you guys in hear might know if the MX 3000 has any "classic problems" with the sound so you can diagnose it even without opening it :-)
I thought the MX 3000's always had issues with the sound, normally the left (I think?) speaker?
I'm sure some techie will be along soon to tell us more. :-)
Apparantly it is not just the left speaker - there is no sound at all :-)
Have you tried plugging in headphones to see if there is sound through the headphone socket? That may help a more techie person diagnose.

Also what are you trying to listen to? Analogue tuner in set or external box?
If its an external box make sure that scart lead is properly plugged in at both ends. If you are using built in tuner check that it is set for the correct transmission for your country.

I will try the headphones when I get some on friday :-)
I have connected no boxes to the tv so I am trying to listen to the tv signal.
By coincidence I have now found a give-away of another MX 3000 with a non-functioning screen. So now I just have to find out what parts to move from that one into the one with none functioning sound. Any ideas?
I want to keep the first one as the chassis here is in the best condition.
Opman > "If you are using built in tuner check that it is set for the correct transmission for your country." How do I do that? It probably is - I found the tv here in my own town in Denmark. But it could be something that someone have changed by error.
Its a very long time since I tuned one of these models. From memory when in the tuning menu pressing Shift + 3 changes the version of PAL between PAL I & PAL BG. I think that model also supported SECAM transmissions. Perhaps some one in your part of the world can check which transmission system the set should be using.
From experience in the UK if the wrong version of PAL is selected you can get picture but no sound.
Sorry i can't give you a more definitive answer.

Also, as you found it in the trash make sure the speakers haven't been removed.
Also check the soldering on the audio amps on the audio board and the reliability of the external speaker sockets ... with the volume up to max, are the speakers completely silent or is there some white noise?
