AUDYA OWNERS WITH AUDIO OUT PROBLEMS:

My left Channel out problems are getting worse!

I had to reboot the keyboard 6 times last night while performing to a full house and packed dance floor.

The embarrassment and the time spent rebooting and resetting the split point, auto fill, all the solo voice choices and harmonizer is just plain UNACCEPTABLE!

I am a very patient man, however I'm reaching the end of my rope with my ongoing Audya PROBLEMS!

The symptoms and causes for the Left Channel completely dropping out are very difficult to pinpoint to say the least.

I can only surmise that it is a combination of both a hardware and software problem.

Sometimes bumping or tapping on the keyboard will kick the Left channel back in, but not always! This symptom and correction technique, would lead you to believe there is a loose connection or a bad solder joint!

Rebooting the keyboard, sometimes as many as 4, 5 ,6 or 7 times will bring the Left Channel back, however it may still drop out again while playing. This symptom and correction technique, would lead you to believe it's a software glitch or a combination of both!

I will take the keyboard apart ( Again ) today, and go over absolutely every wire connection, every solder connection, every ribbon connection. I'll examine the motherboard and sound board with a magnifying glass looking for a hairline crack or a loose chip or anything suspicious.

I have a new replacement motherboard and I might as well replace that also!

I'll do my best guys to see if I can find ANYTHING that might be causing our problems!

What bothers me the most, is the fact that Skude has replaced all of his hardware and is STILL having the same problems!!!!!!!! Which leads me to believe it is a Operating SYSTEM problem.

My searching, my time and my efforts may all be in vain, however I must at least try to find something.

If I find the problem or problems, Ketron better offer me a job in quality control.

It would appear that whoever is currently in charge of quality control needs to be FIRED and replaced with someone that knows what they are doing!!!!

I'll post any and all findings here if I come up with something or not.

Wish me LUCK!

Jim

Jim,

I wouldn’t start looking at the PCBs you will never find any faults with a magnifying glass, its 10,000 volts it needs across them. I think this is all software related and I don’t think you are going to get it fixed, my Audya has just started playing up after no problems at all since the last update. I have had two INT PHASE ERRORS on boot and about 8 lockups all recently, I don’t know what’s going on but I thought it was all cured , not so. There is only one thing to do now before the bottom drops out the market.

Tony

Tony, You are probably right about the problems coming from the OS.

However, this is my question: When I bump or tap on the keyboard, the output sound will flutter or the Lt. Channel will kick back in or out!

Doesn't that sound like a connection or bad solder problem?????????

Jim

Yes it does and its time to take the top off again!

Tony, I have the top off right now! All ribbon and wire connections are snug.

I have not removed the push button PCB yet. I'm a little hesitant about pulling that off.

There is 18 mounts held on with nuts holding the right side board in place. Three ribbon connectors between the Left side PCB and the right side PCB.

Your thoughts about taking that board off and checking connections?

Jim

Here is a preliminary on Audya attempted repair.

Unplugged and replugged every ribbon and wire connection in the keyboard.

Have turned off and back on the keyboard 15 times and both audio outs are perfect.

You might know, while I have the top off it boots perfect every time.

Could I have lucked out and discovered it was just a connection problem?

We'll see. Playing both tonight and tomorrow night. I'll re-post Tuesday and let you all know.

Jim

Jim,

Can you play the KB lying on your back, with the top off, only joking... I don't know what to suggest you do, there are so many small pins in those ribbon cables, I am not certain if Ketron make them up themselves, if they do and they are not getting pressed home properly there could be a problem. But I don’t know of anyone who has yet traced this speaker problem to a loose cable only AJ says all the problems are loose connections.

These things reported about loose connections etc. certainly don't encourage me to
buy any Audya.
I've had some keyboards through the years, but not any who had to be opened to fix
loose connections to make it continue work, not even the SD1.

If the company where I work deliver that kind of faulty products we would be out off
business and the market, and staff would be without jobs long ago!
I don't know about Ketron, but we have something called Quality Control that follow
from the start at the planning and engineering department through the whole building
process till boxed for shipping to prevent bad products leave our factory.
Also different kinds of connectors have different kinds of safety to avoid disconnect.
Imagine a ship movements cause bad contact or connected wires to fall off?

To me it looks like too many items leave Ketron factory in a shape that customers have
to take action by i.e. open the KB. And when open and do selfmade repairs, what about
warranty issues?

Cheers

The ONLY way to troubleshoot loose connections is with a volt meter. You must know what the nominal voltage is at each test point and then take tests to see where the Audya deviates. This will trace right to the problem.

Can an average home user do that?

I didn't think so. Grrrr!

I just don't understand this.

Why are we not having these problems in the UK yet in the USA you seem to be plagued by them.

Could it be voltage/current related?

If that is the case and that there are NO problems in the UK then you may have a good point
Is there no one out there having any problems with their ketrons in the UK guys ?

Hi again all,

Just returned home from playing a gig. The Audya performed perfect.

Unplugging and re-plugging in all the cables inside may have done the trick.

Playing again tomorrow night. Let's see if I can have another glitch free night.

Will post outcome of tomorrow nights gig.

Jim

YES, this is hardware issue...Take it from an ex-IBM service man...DO NOT use a voltmeter anywhere on those boards!
Todays typical VOM meters will load the ciruit and could cause blown components(if you don't short something out yourself anyways)..AND watch out for ESD (static) if you touch one of those components with you finger or a tool with a static discharge on it...BAM! Blown circuit.

Those circuits run on very low voltage and current. An osciliscope would be needed to work on the circuits and if you saw the schematic you would be amazed at how complex it is. Not the type of work for an owner.

If I were working on this issue, I would carefully and delicatly take an INSULATED tool (wood, plastic) and gently push/move/press/prod etc very slowly around on the circuitry. WHILE continuously playing. Make it fail.

Also, maybe it is heat/cold related. Now that you have the cover off...things may have changed on temp.

Also, you could WITH POWEE OFF, spray the components with freon to cool the circuits, then power on & test. Alsoa hair dryer used carefuly can suppy the opposite help.

If you find a place where you can make it fail...I would get Ketron to fix it. I would not tell them I had it apart!

You could say..in this or that area of the keyboard (covers on) when I vibrate it...it fails.

Quite honestly, I think you would be better off on a new board under warranty to return it for service OR better yet make them give you a new one!

If you scrw up here working on it...the results could be very epensive.

Leeboy,

There are no Ketron keyboards going back to the factory, Ketron don't do that. Your dealer will need to fix it and I don't care how far you are from him, he sold it you he should get it fixed.

Hey Guys:

Two nights in a row, my audya Played perfect!

Finally may have corrected the problem!

YEA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Jim

Jim,

Just beginners luck, it will do it again don't your worry.

Tony, I'm sorry but I don't share your pessimistic view.

My glass is always half full, not half empty.

My Audya continues to perform perfectly.

It normally would have given me an output problem by now.

I'm happy to post something positive about the Audya.

Instead of the normal ongoing negative crap that has taken over this forum!

Jim

That's great Jim....good luck with the Audya...nothing like Positiveness from fellow musicians in the trenches!!
sometimes ya gotta take the Bull by the horns!

Jim,

I am not saying it will but if it does I am sure you will lets us know and then we can do like whatever you do.

Hey Tony:

Day five, Practiced and played the Audya ALL DAY today.

Still perfect! Not a glitch to be had!

Jim

Skude ,


Perhaps Nitelife as found the answer, have you tried all the plugs, you must have you have changed all the PCB

SKUDE:

My Audya once again played perfect at last nights gig. I also played it for six hours during the day....perfect!

All I did was disconnect and reconnect every ribbon and wire connection I could find.

I don't know for sure which one or maybe more than one was causing my Left Channel Out Problem.

I suspect and recommend to you this: ( If you are still having problems with the audio outputs ).

The yellow and white and short black wires connecting the Sound Board and the Top Right Panel Board I believe is where the connection problem lies.

I know you have replaced most if not all of your PCB's in the keyboard and the ribbon connectors had to be unplugged and replugged in to do the replacements.

However did you unplug and replug in the connector on the ( Top Right Panel Board? )( Yellow, White & Black Wires. ) Probably not! Really no reason to do that when replacing all the bottom PCB's.

I strongly suggest trying that! Also try cleaning that connector with a little rubbing Alcohol and a Q-tip while disconnected. Disconnect and clean the connector at the Sound Board also. Also check that the top panel board's mounting nuts are all snug just for good measure. Mine were all snug.

Again, I can't say for sure that connector is the culprit, but through a process of elimination I suspect it is.

Give it a shot....nothing to lose! Maybe finally like me you'll get rid of the Aggravating Left Audio Out Problem!!!!!

This suggestion also applies to any of you out there having Left Audio Out Problems.

Let us know the outcome.

Jim

Glad to hear you have managed to sort the output problem Jim. well done!.

Jim
Glad you have solved your problem, must have been very frustrating when you play that much.
I don't have problems with any output channels. when I loose outputs it's after the INT.PHASE error message apears. Then the Exit/USB button lights. There can be weeks without that happens. I've had more problems with Left Sound that drops out. I have checked all connectors many times. Last week I used the Audya in my band. (not using styles) worked perfect, played fine all week Yesterday's gig I used my Korg, I really missed the Audya sounds and the keybed. If I can get myself to trust the Audya I will probably use it in the band all the time.

SKUDE:

When you say Left Channel Drops Out, isn't that the same as I've been posting about?

Did you check the connector on the TOP RIGHT BOARD that connects to the SOUND BOARD??????

Jim

Jim
Not left channel, I ment left voice. The one assign to the left slider voice. Sorry.
skude

+hi skude,
I hear of your left voice-problem.
I`ve got this problem ever, when I use the
fade out button. Only rebooting solved this problem.
Do you have a similar problem?
Keep swinging

Hi
I never had any problems with left voice using the Fade button, works fine.
