Juno G Screen Clarity/Quality

Wow, there is whole club of bad G owners!

I have bought one in spring 2008. For about a year LCD has only different contrast in different quarters. It was Okay, we do not used to complain about every little problem here in Russia. But later, LCD sometimes has started to failing in various ways. For example, the part of display may freeze when some top pixels are on (some edit screens). Or other weirdest fail: Left-Top quarter displaying in left-BOTTOM corner and LT and RB quarters are scrolling down as they are out of V-Sync. Just imagine this messed up picture! After some resets it had returned to normal state and i didn't had that problem again for month or two.

Sometimes it happened on rehearsal or at home. "Oh, okey, it's not a live performance, i'll deal with it later when i have time". But once this bastard messed up display right on our gig! Fortunately my performances was prepared to just increase it's number and play.

When i called in our local service center in October, 2009, ready to order LCD unit, manager sayd that there's no avalaible units right now and promised to call me later and took my number. 8 manths has passed and still no call, no answer and display just degrading deeper and deeper.

Once it started scrolling when i just turned keyboard on but haven't yet plugs inserted. Magically, when i connected line outs, problem has gone!

Now there comes the most hot summer ever known and Juno's LCD may scroll during all day long.

I don't know what to do. When i bought this one i had good work and was able to buy such expensive things like synthesizers. Now i'm unemployed and unable to purchase new LCD unit. And i can sell it — no one will take failing synthesizer! 250$ for LCD is about 1/3—1/2 of our monthly earnings.

What do you think, does Roland still provide free replacement?

hi there! if you still have warranty rolandrus will replace it for free, otherwise it's something like 3500rub... i had the same problem and replaced display myself 'cause rolandrus did't have them.... i recieved a letter from them saying they reicieved displays.... it was in april or in may.... they located in Moscow....

Thanks for your advice!
I called them and at the same day they replaced LCD with no charge for new unit! (My keyboard are out of warranty). All entire work took less than one hour and about 60$!

By the way, new LCD did not yet malfunctioned but it seems that G's LCDs are all quite far from being perfect.
(http://rpocc.livejournal.com/183862.html) 1st and 3rd pic are new unit and 2nd is old faulty unit.

wired, rpocc.... replaced lcd with no charge without warranty???

and 25-th was sunday.... Moscow is not in Israel ))) seems you are like god ))

Update, well a little over year after having sent my juno g in for new display the plague has returned, the only difference is that the screen now goes completely blank, that makes for a very uncomfortable situation when that happens in the middle of worship service on sunday morning, no way to see your patches,key transposes ect. I guess I will try to once again contact roland and see if they will do the right thing and make this product "fit for use" BTW I noticed another post on internet on retail of juno g going down to $750 is that not just another nail in the coffin so to speak for owners that have in good faith paid the full price and yet have had to deal with the contiued probs with the displays going out just past warranty.sorry for the ranting on, I am just dissapointed in this product at the moment and feel that roland needs to come to a more permenant solution than 13 months per display

gstrat isn't alone with the issues returning.

In June 2009 the original LCD went berzerk. I got it repaired at no cost (yay) and have been playing along fine until about a month ago when the display issues with the new LCD have come back. I'm getting very strange things going on. A bunch of pixels are randomly dead... or wait, no they aren't, those are fine, but now other ones are dead... wait, what is going on here. When I load certain songs, there are really dim/dead areas of the screen, and other songs get to where holding buttons (such as STOP) causes lines of text (such as the PART MIXER title) to turn into random garbage.

I just don't know what to do about it anymore. I'd feel kind of bad selling it, what with it being my first real synth, and the display being bad.

So I snapped some pictures of things my LCD is doing.

On RolandUS e-mail support they pretty much flipped me the bird. I'm quite disappointed with Roland at the present, needless to say.

yep - join the club.

Today my Juno-G screen is 95% readable. For nearly a month I was lucky to get half a screen, usualy a quarter would be viewable - I had given up on it as unworkable, not to mention an inspiration killer.

Reasons for fix?

It has been warmer recently, we are just moving into summer, but today it was raining hard, so the humidity theory maybe does not apply here.

What I did do (today) that I'd never done before was midi-out from Juno to my MC-303 just so I could use Juno as a full keyboard controller for the 303. I had heard theories that plugging certain things into the back of Juno (and/or unplugging) has been known to cause/fix the screen error.

Makes you wonder if there's some sort of 'earthing' process going on?

So there you go - another theory for the pot.

UPDATE: Next morning after leaving Juno on, the screen is now 100% clarity, better than it has ever been. Get those 5 pin dins out of the cupboard everyone

interesting method MeNotU ..

but for purpose of these posts, what you all have tried to fix this bug ? is there something that really solve this problem ?

cause I´m in the club yet.

thanx

Well, here I am again, just got my Juno-G back from roland repair with LCD number three. They said they turned on my Juno and "burned it in" for 24 hours, they could not get the LCD to malfunction but replaced it anyway, not sure what message thats sending out other than they have to know something is up with the LCD's but dont seem to be forthcoming about admitting there is a problem. Are they really fixing the problem or just putting a band-aid on it and hope we'll grow weary of sending our juno's in every eight months to a year and just give up. I must say they did do a update version 2 and sent a supplementry manual, I guess time will tell how how all this pans out.

My screen has been 3/4 dead for about a year now. Since my synth is out of warranty and people who have had it fixed have reported the problem arising again, I just havent wanted to put down the money on it.

Now it sits in the closet collecting dust. Sad really.

Well, you can use the juno with the computer and the editor. You can't use the sequencer, program the arpeggiator, or record audio, but playing programs and performances is possible with a computer even with the display of the juno broken.

Hmm.. I actually did not think of that. But dont you have to put the juno into usb mode? I dont recall how thats done and I cant see any of menus.

Has anyone been told yet what's causing the display to go bad ?
My Juno - G has been with me for about 4 and a bit years now and my screen is absolutely crystal clear.
Maybe I'm just a lucky one !
However I really look after my synthesizers.
I always vacuum and keep them in a cool environment.
It would be interesting though to know why the screen display is going faulty on you guys.
