Backlight Problem

Subtronik · Post by **Subtronik** » Sun Jul 19, 2009 7:46 pm

When turning on my Voyager today I saw the backlight go dim for a few seconds, then go out completely. After about ten seconds it came back on. I didn't touch or move a thing during any of this.

I played with the dimmer knob afterward and it's working fine, so I'm pretty sure it's not that.

Could it be a loose bulb? Why would it flicker if the Voyager wasn't being touched?

I'm going to call Moog tomorrow, but if anyone has any ideas I'd sure like to read them.

Could it be the light dimmer pot?

I had two broken pots when it arrived last month, so it's not completely out of the question.

Not a broken pot come to find out.

The pot was switched out and everything worked fine until a couple of days ago when it did the same thing.

The backlight inverter is bad. I shipped it back to Moog to be worked on again.

I hate not having it in my studio...

Hopefully that will be the end of any problems.

I'm having a similar problem, happened today for the first time though.
Instead of the blue back lit panel going down it goes to full bright and when it does so the dim control doesn't react when turning it off. After about 5 minutes it worked normal again, very weird.
Now if this a backlight inverter issue as I'm reading here, I'm net very pleased to ship it back and fort to the US and would prefer fixing it myself if I get some instructions of course. Could this be a bad contact/plug or something?

Thanks for any info, cheers

You could switch out the inverter yourself if you're good with soldering, but the steps are a bit complicated. I'd leave it to the pros.

Could this be a loose contact issue? Ive thinking to open it and have a look for any loose contacts/components since it happened a few times after I moved the voyager a bit.

That was the first thing I checked and was not the problem in my case, but it's a good place to start.

I just had a look inside and found the middle gray connector out the 3 that connects the right board with the middle to be a bit loose, so I put it back in place, also found a screw loose that holds a gray wire in place on the back.
Anyhow after booting the voyager up again the back-light is completely out now. Before they went from dimmed to full bright at random moments then back to normal after a while. So my guess it's the inverter as well. Hopefully moog can guide me through fixing it.

Hopefully you can do it yourself because not having your Voyager with you can be painful.

Absolutely, I could say it a thousand time a day what a great instrument this is, though most people I know never heard of it ... they think I'm from some other planet if start talking about music and gear ... lol

From what I remember, the steps for changing out the inverter are around 6 to 10, and involve soldering.

I send a tech support request a couple days ago, Ill see what happens, soldering is not a problem for me, though the inside of the moog looks a bit complicated

hmmm weirdness... when I booted up today the back-lights where full bright again and after an hour or so it still was, no matter if I use dim knob it doesn't respond.
I just figured when I lift the unit up at the right side and put it back the back-lights suddenly work normal again... so my guess is that it might be a bad contact somewhere after all.
Any ideas where to start looking before I open it up again? How can I get access where the dim knob is located?

Thanks
