yamaha dgx 620 lcd screen brands

My respect! this is the truth, My repair lasted a few month and finally I changed the screen module to a new one, it"s cheap in aliexpress. I can see some improvement and so far so good, 3 years already.0

This Tuesday I opened the DGX620 and checked the display. I saw no way to open it easily but when lifting a side tape I came across two (only two) backlight leds. There it was easy!

I had some similar issues with my DGX-620 that showed to be due to pressure of the flat cables contacts. This was solved using a small piece of cellulose acetate cut from a 35mm negative and inserted in between the display flat cable end the connector.

Awesome instructions. After taking out all the screws and the board, I didn"t think it was going to work because the connections on the LCD board looked perfect. But I followed the instructions exactly anyway. I have zero experience with repairing electronics but the instructions were so good that I fixed it on the first try. I especially appreciated the detail of setting the screwdriver torque to 1 so as not to strip the casing when putting it all back together. Thanks!

Great advice. Thanks! Looking to buy one of these very cheap (because - you guessed it - screen problem!). Before I attempt to fix/replace... is it possible to play as regular piano WITHOUT screen function? My daughter needs a nice keyboard for piano practice... Hate to pass this one up!

Yes, you can catch the offer, the overall quality and durability are ok, as it made by YAMAHA, sound quality is decent if the internal speaker still original, or you can just connect to an externally powered speaker system. one thing I feel the keys are little noisy compared to a Casio, the strike sound, maybe the shock absorber is getting old.... Mine one is about 7 years stationary use. Hope this help.1

Thanks for the advice on the anisotropic conductive film cable. My DGX620 LCD was down to half screen and I wanted to avoid the cost of replacement, when it was clearly only a connection issue.

Hi there! glad my note helped in solving the issue, seems it"s a genetic bug of all DGX keyboards (i just can"t call it piano even it sounds good, but the keys stoke feels toy). I do recommend you have a hot gun to finish this kind of job, as the iron slide quickly on the contact ribbon, maybe may become open again in a few days. good luck!

Here"s a Yamaha DGX-620 keyboard with a broken LCD. Judging from the fact that there are quite a few videos and tutorials on how to exchange a broken LCD with the proper spare part, I"d reckon these LCDs break quite easily and often.

I was a little surprised to get a quote of 130€ ($150) for the replacement (Yamaha Part # WG299100), and I was looking for a replacement that"s cheaper. As this is a fill-in instrument, and long out of warranty, I wouldn"t mind not getting the original part. Also I don"t mind the tinkering.

Enter Pollin, a company selling electronic remnants, such as bags with 1kg of capacitors, sold as “perfect for tinkering”. By chance, they sell a “LCD-Modul NAN YA LTC79H202T50K, 240x320” (order #121307, €4/$5) which, on closer examination, is electrically 100% compatible to the Yamaha display. Only with a slightly different, smaller shape, and with a different pinout. Also, they sell the exact same flex-cable that Yamaha uses to connect the LCD to the CPU board: Flexprint-Kabel AXON FFC1.00A14/0200L5-5-10-10 (#562251) (€1).

Looking into the datasheet of the LCD provided by Pollin and the Yamaha DGX-620 service manual easily found online, it"s clear that electrically the display is compatible.

FR (first row) is FLM (first line marker), LP (line pulse?) is CL1 (data latch), XCK (x? clock) is CL2 (shift clock). Everything else has identical designators. Sanding off the back of the replacement LCDs PCB a little to have good bonding to epoxy glue...

Ugly patching of wires from the 14-in cable to the pads on the LCD according to pinouts shown above. After soldering the wires (which is hard on the flexfoil, as the plastic melts and the copper traces of the flexfoil will move around, creating shorts) and emitting a few prayers to the deity of choice, a picture appears! :-)

Then I added the display to the original plastic part from which I removed both the LCD logic and all the light spreading works. The complete LCD module almost fits in the cutout for the old glass, only a small plastic ridge had to be removed with a xacto-knive. I had to add a small slot for the flexcable, to feed through and added a hole for the big blob of goo by which I glued down the cables so that they don"t become loose.

Update: As Ulrich pointed out, one can directly solder the cables for the LCD backlight to the cables going to the two-bin connector on the power supply on more recent models of the keyboard. Some onlder ones have high-voltage for an electroluminiscent foil, though, so beware.

Please keep the item in its original condition, with brand outer box, MRP tags attached, user manual, warranty cards, CDs and original accessories in manufacturer packaging for a successful return pick-up. Before returning a Tablet, the device should be formatted and screen lock should be disabled.

I got an error when visiting www.fullcompass.com/brand/yam-yamaha/replacement-parts/musical-instrument-parts/keyboards-and-midi-parts/?page=1&categoryOrder=Z-A&ipp=48.

I came across this website while looking for a solution for why the screen looks so messed up on my DGX-620. I am taking the time to post this comment cause I was actually crapping myself at how to fix this issue. Now that o have thanks to you guys, holy crap thank you soooooooooo much. CHAMPIONS.

I have problems with my LCD display also! At the back of the Yamaha 620 you will find to the right a small protruding knob! This will adjust the light.

If the LCD is not displaying at all it could be a faulty connection ie where the temperature changes in the room and the soldering etc expands and contracts, therefore, when its cold it will contract and the connections fail, written information will no longer show. When it expands the connections are made and you will have the information in the LCD screen! This is what I was told when I asked in a music shop in Evesham. Hope this helps!

The display of this Dix 620 is only showing right side half and the left half is blank like a white paper is covering the left half of this display widow. Can you give a hint to get the left half working.

I have a DGX-620 and it has started to play a B+C second when I hit middle C, but only when certain other notes are being held in sustain at the same time. Sometimes only the B sounds loudly when C is hit, but again only with other note combinations in sustain. I have tried both the last-white-key and 3-blacks+last-white key resets, but there is no improvement. Anybody know what to do?

Dear Peter: The symptoms you describe point POSSIBLY to the rubber underlay pads under the keys being dirty/defective. I do not have a lsiting for a Yamaha Repair Service in Honolulu, but you can either ask the store where you boughT the unit who they use for repairs, or contact

I moved and when i tried to hook up DGX 620, nothing happens. The computer sais I have new hardware, but I have used it before and it is not new. Then, I try and download drivers and it downloads but the screen stays white and I can"t find the driver download. My computer says that I don"t have a DGX attached.

Dear Sue: 1) WITHOUT HOOKING UP THE DGX 620, if your computer works normally, it is an indication that 2) the patch cord from the DGX to the computer may be defective 3) you may not have followed the instructions in your Owner"s Manual when setting up the DGX after your move. The sequence of steps as required is important and must be followed. I hope these comments are helpful. Please post a follow-up message in this Forum to let other members know haoew you have fared. Thanks and good luck.

We"ve had a litlle accident with our DGX620: our cat has peed over the keyboard. The man at our local musicstore warned us, that in time the circuitboards underneath the keyboard will get damaged by the acid of the fluid. First it functioned well, but after a week or 2 indeed hitting a key resulted in messy notes, as if all notes are messed-up and played in random highs.

So: the contactstrips/arrays underneath the keyboard need to be replaced (all 4 of them). Total costs (including worktime) about ? 400,00. We didn"t think it was worth the investment and have now bought an dgx 630 (with keyboardcover :) ). However.. the soundpart of the damaged dgx 620 is still functioning well. If i connect it to my pc, all midi-files and internal songs and voices are still sounding correct. I can even trigger it by using an external keyboardcontroller via USB through Sonar on the PC.

Surfing the internet has resultet in very poor info about keyboards for the dgx 620. Our man at the musicstore told us, that FATAR produces good value for money keyboards. I have a few questions about the damaged arrays:

If all gets too expensive i am planning on ripping the circuitboards of the sooundmodule out of the dgx casing and rebuild it in another casing, thus using it as an soundmodule (kinda rackversion of the dgx 620) and then trigger it with my easycontrol 49 usb midicontroller. I even have the instrument definitionset for use in sonar, so i can access also the sweet and livevoices.

Sonar is a very complex midi/audio recording programm, so i guess i will be spending a lot of time figuring how to do all the midi stuff according to the 620.

Question: is there a way (or a programm) wich helps me to get more control over the dgx620? For example if i want to start a style using syncstart, it now don"t react on keyboardhits from my keycontrol. Also i want to be able to use split and dual etc. .... the functions that can be accessed on the dgx by pressing the buttons. But i want to access/controll them via midi. Can this be done?

Dear Harry: Dick has beaten me to the punch, but as you will see from what follows, he must have been reading my mind while I was preparing to reply: "I believe my first message mentioned probable damage to the Rubberpads and Copperlines (TRACES) of the Circuit Boards, and how they might be cleaned. I also indicated how I might go about disassembling the Unit (Making notes along the way). That process as you are beginning to see, is going to be a ?work of love?. That is why Yamaha (and Dick and I) normally discourage any DIY activities. As far as the Traces of the PCBs are concerned. You can always ?bridge? any corroded ends with carefully soldered pieces of copper wire (Use low wattage iron.Never soldering gun). You are right about the Sensor points (Graphite Dots and the Key Velocity). As to updating threads, you have the option when you end your post to request alerts when other members enter their posts on the same subject. I am not a PC nerd and don?t know how to post pictures. Isn?t it done in the same way as you did in your original post?

NEITHER DICK NOR I HAVE ANY CONNECTION WITH YAMAHA. WE, LIKE YOU, ARE JUST MEMBERS of this Forum giving our best efforts to a friendly meeting place for enthusiasts. Mantius is the Webmaster and if you refer to the subtitles to the left of all posts you should find one that says ?Contact Mantius?. Dick, by coincidence, may have a Service Manual for your DGX, but I doubt it, and to purchase one you probably should get in touch with the Yamaha people at the following address: Yamaha Music Europe GmbH Branch Benelux

You have to understand that we have nothing to do with Yamaha as such or any other factory. People who are answering questions on this forum are keyboard enthusiasts, with a bit (more or less) experiences, (good or bad) with in general one or two Yamaha keyboards and/or piano"s.

Dick, is there any chance that u can get me a technical manual in which is described how to disassemble the keyboard and its arrays? (pdf will do). I understand that Yamaha only communicates via its retailers and not directly to endusers/customers, but i was kinda hoping u could pull some strings for me at yamaha :).

2. Being as mechanically and electronically inclined as you obviously are, why not do everything possible to salvage your 620? You have nothing to lose (you have the 630). Just avoid forcing anything, and make notes as you go along so you will be able to reassemble the unit when the job is done. Start by gently cleaning all accessible parts with a mild solution of detergent and water, followed by a COMPLETE DRYING of each part. This means all the Keys, Internal Circuit Boards (Traces), Sensors (be they rubber pads or other). Be aware that some of the internal Components may be static-sensitive, so take the necessary precautions to keep them safe.

Hi, I recent bought a Yamaha DGX 620 and i was wondering if there is any way to open USER SONGS on a windows computer, possibly with windows media or be able to open the file as a mp3 file or a .wav file.

We have the DGX-620. Is there any way to link all the songs together so you can listen to continuous music instead presing the start/stop button and selecting each song?

Dear Stefan: If you first google Yamaha DGX 520 and learn about that Unit, then do the same for Yamaha 620 you will be in a position to post any lingering questions in this Forum. No disrespect is meant, but you should do some "homework" before posing any questions such as yours. Most participants do not own more than one keyboard, and presuming the one they own is one of the two in question, they have no way of really responding without doing some "homework". All this said, please accept my advice in the positive spirit in which it is meant. I look forward to helping you further, so please don"t be shy to post future Forum messages. Keep well

After plugging in the power supply I push the "on" button and nothing happens. No display,zip. The power supply (Yamaha of course)works with other equipment but the Dgx620 has no response. No lights of any kind.

Hit "Function" on the Keyboard, and then on the upper right hand side hold down "Demo". This then opens up the PC mode on the little screen on the keyboard. Now use the scrolling circle (where it a "Data Entry" arrow is pointed) and move it up a couple notches to get to PC2 mode!

Also, for Mac users, just as a side note: when you unzip the file, there will be a lot of "installation guides" to open. Just skip all those and double-click the "Yamaha USB-MIDI Driver.mpkg" to get the real installation started.

1. I would like to hook up my dgx 640 to my mac and go into garage band and be able to hear my actual piano sounds and record them in there ( How do i set that up and how do i listen to it while i play it? if i am going from a 1/4 thats connected in back of dgx640 to my macs headphone jack, that means i cant hear as the headphone jack is in use

1) Get a 1/4inch cable, which you can connect to your yamaha in the output port on the back. Connect it to a mixer, and connect the mixer to the audio input jack on your Mac. If you have a macbook pro, the input is the headphone jack, but you need to go to system preferences, sounds, and change the port from an output to an input.

Hi all..need help. I have been able to record from dgx to GarageBand..(using the garage band sounds).HOWEVER, I have nit been able to record the full sounds and effects I want to use directly from my dgx 220 into GarageBand...why is this?

I"ve got a Yamaha Portable Grand DGX-505, and I"m trying to connect it to my Mac laptop (running OSX 10.5.8.). I"m trying to be able to record into Logic or Garageband through MIDI. And nothing works. :( I installed the driver mentioned on this page, and it installed fine. Garageband recognizes one MIDI input (presumably my keyboard) but won"t do anything about it. Any advice is welcome, I"m at my wit"s end here. Thanks for your input :)

Dear Tracey: Google the Yamaha Parts Dept. (Essex in UK??? Then google Yamaha UK). Provide your model number, etc., and hopefully you will thread your way to the webpage. Happy hunting!

I want to use the A-B repeat function on my DGX-620 a bit like a loop pedal i.e. record a phrase and have it play over and over so I can play along with it.

This hasn"t been looked at in a few months so hopefully there is an answer soon. I"m having the same problem. I"ve been able to mute it so that the metronome doesn"t play, but now it"s just a gap where the sound of the metronome would have been. I"m using a DGX-230. Here"s what I"m doing. I recorded a piece onto the first slot in song memory that I want to loop. Then I press repeat A-B before i play it back so that it records from the start (as it says in the manual). I then press repeat A-B again where i want it to end. Everything works except I get a get an 8-beat gap between the looped recording. How do I get rid of this? Thanks!

I have a DGX 620 which is 2 1/2 years old. The display screen has faded and only shows 50% of the screen. This appears to be a common fault with various owners reporting the same or very similar problmes. I assume that as this appears to be a faulty part this should changed free of charge.

I never followed this through but have noted wide world that this is still a problem for DGX 620 and similar models that use the same screen. There is a solution on You Tube for replacing the screen yourself.

My Yamaha DGX 640 is about 1 (one) years old. Today after switch it on I got a badly surprise when only half of the display was on. The other half was fade-out. Just right in the center. I have the ORIGINAL adapter which I bought with the piano. If it is a common problem, THEY SHOULD REPLACE IT FOR FREE. No question about it.

I have a Yamaha DGX 620 Grand Piano and the F# and C keys have stopped working when I press them. Can this be easily fixed? Can someone guide me on opening up the keyboard to check for a loose connection, etc.

I have the same DGX 620 and the 3 lower C"s and the 2 lower F and G sharps quit working.. I was playing today and the 2 lower D"s all of a sudden quit midsong! FRUSTRATING. It was a "refurbished" instrument, its just barely a year old -- I hope its warrantied!

You problem, if all C"s and F#"s are not working it looks like a contact pad (for a better word) underneath the keys is broken. If that is the case, it can easily be replaced by a Yamaha repair person with the right tools.

How do I create new styles for the DGX-620? The existing selection is a bit short in the Waltz department and I would like to be able to have a few more.

Thanks for your comment. Only problem is that I don"t see the DGX-620 anywhere. Tons of PSRs and Tyros, but nothing for my keyboard. Is this a case of one name for the UK and different name for the same thing everywhere else (as in some Canon cameras) or am I just not looking in the right place?

I am a computer programmer, among other things, so am not daunted by complex procedures, but cannot discover - even from Yamaha support or Michael Bedesem a year or so ago - how style creation or adaptation actually works.

ations:Dear David: If you are using an Adaptor, it may be defective. Sometimes the output degenerates. Try a new one. If the Display still is blurred, you should contact one of these two Yamaha operations:

I"m planning to buy a digital piano for my 12 yr old daughter. Deciding between a very good condition second hand dgx620 and a brand new dgx630. We want to save some money all right because the cost difference is about $1000. But is there any major difference between the 2 models?

Dear DowmUnder: Thanks for contacting us. Google (separately) Yamaha DGX 620 and DGX 630, and you should be able to compare the specs of the two models. This Forum is not an arm of the Yamaha Corp., and other than the info to be found in the index to the left of this post, our discussions do not include unit comparisons. When you decide which unit you purchase, we welcome you to come back as a participant. Good luck.

I am looking at the Yamaha DGX-630 (at Costco) (I imagine it is called 630 as opposed to 620 because it is at Costco). I see it has weighted keys, but cannot find if it has touch response

I have YAMAHA-DGX620 and i"m playing in the band, but i"m having trouble when using Sustain pedal, because it"s decay just lasts for too long. Is there any possibility of reducing it? I need quick help!

I have a DGX-620 and using the mains power adaptor. the keyboard is on but the key sounds in intermittant. The demo is working ok. The menu function key will only show one setting and cannot be adjusted.

I have PC windows vista. I am trying to record my keyboard sound with Mixcraft 4 trial version. However, I do not hear any sound output neither through the soundcard nor from the instrument (could be it is headphones out jack). I tried to connect my DGX 620 through USB cable and also phone output to PC soundcard. My PC has recognised the USB driver. I have also upgraded the USB driver. Mixcraft also recognized the Keyboard. So what is the issue? Shall be grateful for help.

At last managed to transfer the song data through USB flash drive in Midi format. However, when I played it in Mixcraft4 I found to my horror that the sounds of most of the voices were altered!! (I read about this problem in another site too). Some background style (pre-recorded) disappeared showing blank midi track lines. I later used virtual instrument voices of the software to envelope the sounds. It took some time. I am still to exploit the MIDI feature of the DGX 620 vis-a-vis computer.

Does anyone know where I can locate the plastic cover for the LCD display? The glue came undone and I have lost it. Keyboard is fine, but need to know what I"m playing. Thanks.

A month after I posted the above message the display died again. I opened the DGX620 and the problem was, again, a bad contact on the display flat cable connection.

My DGX-620 is also crapping out on me. Somtimes it works...sometimes the screen looks as though its moving but it"s really hard to read and other times I have only a couple of vertical lines with a lit up but blank screen. Pisses me off!!.. I paid good money for this and by the looks of it, this is a common issue that should be repaired free of charge.Bastards at Yamaha!!

My name is Paulo de Tarso and I’m from Brazil. I also have a DGX620 with problems on the LCD display. Sometimes it works fine, sometimes completely blue !

All keyboards from Yamaha that use this display have problems. I have not analyzed my unit but from the reports and comments from people throughout the web it appears there is a loose solder joint problem on the display itself, as when you tap the back of tail of the display the display comes back to life.

Same thing here. I own two of these keyboards (DGX 620) and both do the same thing. LCD screen fail!! I wish Yamaha would recall these screens or send replacement screens free of charge. I"m willing to go at the screws for 2 hours and do the repair myself. Let"s all say Class action........

I noticed on utube a guy just touching one of the cables to the display and you could see the display change. This was not a DGX620 but a different Yamaha keyboard that uses the same display.

my dgx did have the same error. the dealer believed the display is bad. he sayed i must bay a new display. you open the keyboard. you must lay it at the top and open all the screw.inseits you see conducter plates. you take off all the cable bands which go to the display. now you do contactoil on a soft paper and put it on the contact. now the dispay goes ok.

The problem has something to with the flat cable on the board. If I tap the unit I sometimes get the display back. There is a utube video showing this on a different yamaha keyboard.

Neither Canadian and USA Yamaha representative accepted to help me in any ways. So finally i must agree that it"s the last time i buy Yamaha"s products. It"s a shame that they dont support their products more than that. Too bad my next synth will be Roland, Moog, Casio etc. If i want to repair i"ll have to pay more than $200 plus custom fee $100 plus shipping and taxes $100...Forget it!!!

Unbelievable. If that is what Yamaha is charging for what seems an overly common defect with their units then that is seriously the last time i am buying a Yamaha product. Why don"t they just issue a recall or something of that nature?

Dear Jan: In addition to Dick Rector"s wise caution, you may want to contact Yamaha Canada Music Ltd. at 135 Milner Ave., Scarborough, Ontario, M1S 3R1, Canada

If I was to connect my Yamaha DGX620 to a computer, what cable would I use? Did the piano come with one? (I don"t know if I got one, and my piano was used when I brought it) Or do you need to buy it? If so, where from?

I don"t know how old your post was and you may have sorted it out. I have a dgx500 and Have just ordered a Roland midi/usb interface from Ellaways Music at Kedron in Brisbane. Amanda there was very helpful and convinced me that I didn"t need the much more expensive Yamaha UX16

These replacement keys are for the Yamaha DGX-6200 but will also fit the following keyboards. Be sure to select the group you need from the drop down during ordering.
