Alesis QS-7 Display woes
Anyone have experience buying/replacing the LED display module on an
Alesis QS-7 synth? Mine is on its way out fo' sho'. Half the time it is blank
and the other half it spells out dirty words and insults me..
Thanks All.

I'd call that a feature, wish mine would do that...  The only synth I can get to talk dirty to me is my old Akai AX-80. But if you must get it fixed I would suggest sending it to an authorized service center, might be more then just the display. Might also be able to get by without it if you had software to control it like QSEdit.

I've got an original QS6, and the display on mine gave out about two years ago. It displays random gibberish... random characters that for some amusing reason scroll one character to the right with every MIDI event, so at the very least I have an indicator that it's receiving MIDI data.  I brought it to a repair guy, who after (apparently) contacting Alesis when he was stumped, announced it would take nothing short of a complete motherboard replacement. At prices two years ago, I could have bought a whole new '6. Soooooooo.... if you do happen to discover anything, do let me know. I'd chuck the 6 but I'm still in love with all it's organ and drum sounds, and use them frequently. kevin at forkboy dot net

Thanks for the intel Ohhey and Forkboy........I can get a module from Alesis for
around 60 bucks I think......I plan to open up the QS tonight and check out the
job of changing out the module. Can't be too hard right? (famous last words!)
I will keep ya posted as I blow up my studio....

If the LCD replacement doesn't pan out you could always improvise with the QS Studioware panel or the QS Patch app that are out on the web.

I just remembered that at the time I was looking to fix my QS, the repair guy also told me that Alesis was on the brink of bankruptcy, that they were probably going to sell off their whole keyboard line if not discontinue it outright, so I shouldn't plan on any help from Alesis at all, seeing as how they were about to go the way of the Titanic.
Please let me know how the screen transplant goes... 60 bux might be worth getting my 6 back to full functionality.
Thanks!

This is a good point... I never gig with my QS; it just sits quietly in the corner with the dust cover on. I've got the instrument definitions loaded into Sonar, so I never have to see the screen on the QS.

This sounds like a problem with the QS series because I had the same problems with the QSR module and I saw a QS6 at a local music store that sells used equipment that the same issue. I have a DM5 drum module and it also has this same problem. (Maybe that's why I haven't bought anything else from them in quite a while). I'm not in the market to replace the drum module so using the instrument definitions sounds like the way to go!!!

I have an old QS-8 and have had no problems with the display. However, it has seen studio use only and has not been "roaded".

Mmmm.... That sounds that alesis uses Faulty LCD displays....if im right they use serial inteligent LCD.....the mainboard of the keyboard or module send by serial data what to diplay....you can replzae that with another same line caracter LCD.... if you can take apart that LCD please look at thit close it...if they have a small chip or round glued like chip...that is the LSI chip that have the serial port and logic to diplay characters also gives the refresh clockt to the lcd.... old time untis have DUMB lcd diplays, the board have dicrete IC to manage LCD refresh and to make the interface works... if you can take a close up of the tear apart LCD form front and behind and post it here so i can take a look and advice what kind it is...and maybe we can look for a replacement on the WEB.... if it is a SMart lcd...there are plenty of them on the web... you can found a lot of stuff at www.mouser.com www.digikey.com www.dalco.com

I am holding in my hand the credit card sized module with the lcd display box soldered to it. Now I get now characters, just a nice green glow. Looks like a pretty simple fix,and my ordered part from Alesis should arrive next week.
I will let ya know how the saga continues. Man, if Radio Shack only carried this, I would be made in the shade for about 12 bucks I bet....
And another thing, the keyboard still works great, so I didn't blow up anything
yet! But hey, it's early....

Hummm... that reminds me I wonder if I should replace the backup battery in my 1987 Akai AX-80 synth.. it has been a while. The manual says it's good for 7 years...

I understand rolo95......but I cannot do that at the moment.....
wait a minute....wait a minute.....I project a 66% chance of failure if I ask
spouse for money to buy a digital camera. Will explore alternate borrowing
strategies. Stand by.....

Glad to see this thread is still going, as I've been curious...
I hereby volunteer to crack open my QS6 and take pics of the keyboard guts in question. I've got a digital camera, but I won't get home from work for another hour or so, so stay tuned.

Huzzah! Here's the pics. All of these pics are as high-res as my cam would allow (which is a measly 2 megapixels), at 1600 x 1200. They weigh in at 1 Mb to 1.5 Mb. I wanted to make sure you could get all the details. The screen itself measures approx. 2 3/4" by 1 3/4" outside. Guts of the beast Back of LCD, installed Back of LCD, removed Front of LCD, removed So...... can this be replaced? Anyone? Bueller?

Fork... how many wires are in the ribbon cable that gets in the LCD and can you peel a little the paper stamp that have the bunch of numbers to see what the word is " DATA VISI...." and last is there a header when the ribbon conects to the LCD,,, or a HARD wired (soldered) if you can take a pic ot that it would be WELCOME One thing here it looks that the LCD is SMART...hence the round GLUED black chip...inside the EPOXY is a chip that controls (decodes) the data comming from the KEyboard mainboard.... but it seems that are PARALLEL not serial as the ribbon is like 8 bits wide.... Waiting for your response Fork..... Stand bY........ ORIGINAL: Forkboy

FOUND!!!!!!!!!!! 2 replacements ...guess what... the number 16235 in the paper tag that is printed on a dot matrix printer is the actual model number and yes it is parallel....unlike other smart modules that are serial.... more...... one company offers diferent colors...than the stock green i love the blue baclight with white letters...so you can have an QS synth that nobody has with blue LCD or ORANGE or red....

Holy cow!!! Rolo, you are my new hero. Nice work! I hereby offer you, as a token of my gratitude, my firstborn. I guess my only question is this: my display shows nothing now, but still lights up... before, it did show characters, just incorrect ones. It would show actual letters and symbols, just at random, which led me to believe originally that the LCD was working fine, it was just being fed bad data by the motherboard. Am I wrong in this? Could the LCD unit itself be the source of the gibberish, even though it's being fed correct data? And you better believe that I'm ordering a better color. I'd be the only kid on my block with a tricked-out QS6. All I need now is a Honda "Type-R" sticker.

Fork it depends on 2 things...that the LCD of yours is damaged.....or that the mainboard of the QS alesis...is damaged and sends nothing or giberish... so the only way to know is to look with friends that have a QS sinth and swap the part..... if dont work on a working QS your lcd is faulty... on th eother hand if it works....its always sign that the mainboard is not sending correct data to the LCD or not sending data at all... in that case you need a mainboard replacement... but taking in case....that the QS is still operating...just no LCD.... i think is not the QS mainboard.

Outstanding work comrades! Now this is an example of a forum kickin'
ass and getting stuff done! I am very impressed with the info brought to the table. But like I said, if this part has an actuall cost ofonly about 3 dollars, I will be upset. Think of all the beer I could have bought....

Hey all. I can report that all is now well with the LCD replacement. A really easy fix that ya can do in no time. One thing is that the newer LCD board as shown by Forkboy is larger than the originals, but all ya have to do is remove a bracket and you are good to go! Now off to record a platinum hit....
Be seeing you.

Hey Vuzz, thanks for the update.
So you ordered the new LCD direct from Alesis, and it was about $60?
I'm still looking at the links that rolo posted to see if any of those companies will sell a single screen to a regular joe.
