screen repairs

I ask myself this question, what would Roland benefit from lying about this?

A massive coverup, global conspiracy?

@lawndart

I just read your report on the other thread.

1 week!?

There are two problems I have with this: 1) if you just brought it home and it's broken, why have you not returned it to the store?

2) Multiple Rows of dead pixels? Are you sure this isn't a contrast issue? Dead pixels would be orange. Is it banding, is it vertical? Any way to take a picture?

I'm not saying you are lying, rather I'm confused with you keeping it, and the transpose issue has been noted around here before. Still, there seems to be some confusion about the LCD screen.

In other words, I'm not certain if this is a conspiracy against Roland or what, because it's not making any sense.
So far all broken units were from Z series, now appears there is an A serial broken too? On day 1? I thought the 'A' batch would have the 'MAde In Japan' sticker according to logic, presuming it woul belong to the batches 'relocated' to Japan.
Now, again, something it's not making sense here.

@dbijoux

1) I am going to return it. I just haven't gone back to the store to do this yet.
2) It isn't a contrast issue. I've played with the contrast adjustment knob to see if it would have an effect, but it doesn't. The pixels are orange and they are incapable of turning black to represent text/graphics. There is a horizontal band of these pixels that extends all the way across the screen from left to right. The band is about 4 or 5 pixels wide from top to bottom. When you start up the keyboard and it is in patch mode, it's not particularly noticeable because it is located directly below the part of the screen that says 001 Juno-G Grand. However, it becomes very noticeable once you get into the patch editing screens or step recording because those screens are actually trying to display text/graphics in that region of the screen. In addition to the horizontal band there is also a 1-pixel wide vertical band of orange pixels on the left side of the screen which I didn't mention in my report on the other thread because if that was the only problem, I probably wouldn't care about it since it doesn't really affect anything in terms of function.

hi guys!!! after 3 weeks (july 28- aug 20) my G is back from the service center here in the Philippines to my loving arms.... i must say, they had done a pretty good job of replacing the display screen and pitch bender.... sadly though, they DON"T update juno's to ver. 2.0 .... so i have to order my CF card from Japan which will be arriving soon.... and, yes i have paid for the services since it's been past warranty....i own it 3 years before screen goes nuts... i really appreciate all the helps and tips from all of the guys here for sharing their experiences and thoughts... especially to Derickeys, Blues4Dog, Outsider and Elwood.... i'll be checking for some of the updates on this forum every now and then.... on a positive note, i hope more people can post their serials (especially with defective screens) on this forum so Roland can finally accept that it's their fault and not ours.... IMHO, i don't think 8 or 10 serial numbers posted here will do us good....so i'm one those who encourage everybody to get involved for our and our G's sake.... gotta go now... more sounds to layer...tell you soon how my G performs after having it fixed... thanks!!!!

My replacement JG came in today. I've only been playing with it for about 15 minutes, but have not found any problems with this one so far.

Excellent to hear. Will you include on the serial # list?

Thanks for the update and enjoy.

just saw this thread. My guess from the images on the video is that the streaking is caused by interference between the vertical screen sync frequency and the inverter which supplies (and dims) the backlight (the burst signal). The frequencies (and harmonics) are supposed to be set far apart but the components used to set the burst frequency are temperature dependent, especially the capacitors.

Why I am telling you this? It's possible that in extremis a screen could be brought temporarily back to life or visibility by raising or lowering the temperature gently, thereby forcing the burst frequency away from the vertical sync. (No hair driers!)

Sir jegoy

good day where service center in philippines did you bring your juno G ,How much did the Juno G LCD cost I have the same problem pls. help thanks in advance

I'll say it again, despite my screen being far from useless it was nowhere near perfect, I had it replaced... by another screen of no improved quality. Also, I'll say again, that in the box were service notes that stated the screen was compared with stock components and was not noticeably different, but the screen would be replaced as a precaution.

Given that the quality problems would have been obvious to a 5-yr old, as an adult I can only conclude one thing... Roland (UK at least) know the screens are far from what they should be but don't see it as a problem.

Last week I suddenly got a horizontal line through the centre of the screen and nothing else. Thank God I had no patch, performance or song in need of saving!!!!!!!!!!

We won't be using these instruments in our old age. Not unless Roland sell off many spare parts!!!

Did you ever add your board/serial # to the list?

hi rytess!!! thanks for seeking help....
as for repair labor cost, it's 900Php
the replacement screen is 4,000Php
...have to make a 50% downpayment to start the process
... if you're in a hurry, you could order the screen and have it shipped right away in a week...but you have to cover the fee of 3,800Php
.... or you could just wait for the next shipment....it is up to you if you are willing to wait...especially if you have a spare keyboard to use for the time being...
....upon arrival of the replacement part, it will take another two (2) weeks or so for installing and testing...so patience is needed..(yet again!!)....
....the service center is the G.A. Yupangco Bldg....located at Makati City (Gil Puyat)..... you won't miss it....you could call 890-0033 and a certain Vangie or Stephen should be attending you for assistance.
...hope that helps rytess and i hope you can have your board fixed very soon....i know how inconvenient it is... wish you good luck and have a nice day.
P.S...
i hope your board is still within warranty period...if so, you're lucky and they'll replace it for FREE!!!....don't know about the labor though.

Sir jegoy

thank you very much for your kind help and words May God bless you more

Thank you for your concern and help Got my juno working again more power to all

I've read all sorts of crap....speculation that there is a "bad batch",as if to imply that there's only an isolated few that are faulty,some owners receiving free repairs-while others get burned,some people curse Roland for their lousy customer support,while others rave about it.

My experience is this: the display failed after one year and a half. Since in Europe the warranty lasts two years, Roland repaired it for free. Since many of the failures happened after 18-24 months, users have had free repairs or not according to how long the warranty lasts in their countries and to when the failure happened.
The other question is: is it a bad batch or not? It would be interesting to know if there are some users that experienced another failure after the lcd was repaired. Mine is working correctly (crossing fingers...), so I suppose that the defect has been corrected.
Also, some userslike Robjuno) complained about the LCD quality, claiming that when their screen was replaced there was no improvement. This is a completely different issue. The quality of the Juno-G lcd is not top-level, meaning that if you raise the contrast too much you will see some "smearing" of black pixels on white parts, but this is just the way the display is. You can change it 1000 times and it will be the same. This does not mean, however, that your display will fail. You can go in a shop and see for yourself if the quality of the LCD is satisfactory for you.
