Muted TX81Z...

Post by Spadz » Sat Sep 01, 2007 4:57 pm

Hi,

I have this TX81Z that just stopped producing any sound. I can see it receives MIDI signals and all buttons are fine. Of course, the output is at max (in case someone asks...).

It just stopped.

Does anyone have any ideas?
I know some synths and computers can do some strange things when the internal battery is dead, but all the programs are still there. So i don't think it's a battery issue ( i could be wrong). Someone i know said it could be the converters... Is that possible?
I know that last few weeks before it went mute, i occasionally had to restart it because it wouldn't sound anymore.

Anyways, any ideas would be appreciated.

Thanks

Of course, while in there check the battery. Below 2.5V change it (3V CR2032).

The A/D Converter could be at fault. I'd check around and test capacitors and transistors while at it.

I'll test the battery. I'm going to leave the capacitor resistance thing to pros like you.

I have a few synths to have fixed. Some i'm not sure it's worth it, some i need rather fast. Would be simpler to explain on the phone.

Is it possible to drop you stuff on saturdays?

I'm going to call you during the week. OR would you prefer me giving you my phone number to call me when you can?

Thanks

No preference. Call at about 4h00/4h30 on the week - that'll be a good time to reach me. Anytime on the weekend. The same applies to the drop off.

What's the deadline? I might not have all the parts in stock. And if I order, they're will be a delay, depending on the nature and rarity of the parts.

You can personally reach me at: steph.jATmuzikelektronixDOTcom

[EDIT] I am currently working on a grocery list for my suppliers... with all the parts that could have failed.
