I have a Technics SX PR 902 that recently stop getting any sound from the speakers. Sound will work with the head phone but that is it. I looked for any obstructions in the headphone jack but did not see anything. I also unplugged the connector from the headphone that goes t the sound board in case something is wrong with the jacks but still no sound. I have the correct power from the transformer and from what I know everything looks okay. I am looking for any advice on what to look for or try to get the sound back. Also any advice on checking the sound board or other thing that may cause this problem.

Thanks

John

Hi John,

Sorry, this isn't a helpful reply.
I was wondering if you managed to find an answer as I have the same issue with my 903.

Cheers

My fix was a broken solder joint on the headphone jack circuit board. My headphones get used a lot and even thought the headphones were removed the broken joint made the piano believe that they were still in. Once the joint was re-soldered everything worked fine. Hopefully your problem is that simple as well. If you use the headphones a lot I think that this would be a good place to start as well as a cheap and easy fix. Let me know how you make out.

Hey John,

Thanks for the reply.
I haven't got round to trying it yet, but it was a really helpful response and it'll be the first thing I check when I open her up.

I'll let you know how it goes.

Kind regards
