roland td 20 lcd display manufacturer
Like many, I have a TD-12 with a non-functioning display. I replaced all the ribbon cables, cleaned contacts, etc. The display is just bad and there is no replacement.
So, I want to make a display retrofit with probably an OLED display and a custom made adapter. I"m an embedded systems engineer with over 35 years of experience. I"m going to attempt to reverse engineer the communications scheme with the display and figure it out. How difficult can it be? It would be much easier if someone had schematics or relevant tech info to share but I"m going to try anyway. If any other engineers want to collaborate or if anyone has schematics or tech info, please contact me. Thanks.
Each OLED includes instructions, spare LCD ribbon cable, and spacers needed to mount the new OLED and for the power unit. All the OLED"s have been tested and work great.
This is to help address the question I come across about once a week. The TD-20 LCD screen. Right now in 2019 and dating back to sometime in 2018 Roland does not have replacement LCD"s to fix an issue that affected some TD-20 modules. The issue seems to be that some pixels fade or die over time making the screen unreadable or hard to read over time. I have come across this issue a few times myself on trades. Its to the point to where I ask if this is an issue with a prospective trade and I am hesitant to take them on trade if there is any doubt. There are not many online solutions for this that I or my service person have come across. Roland does not have the part available and can"t get more from the vendor. We are not sure if the vendor just stopped making the item or Roland decided to stop ordering the part. If anyone knows of a solution or any more info please post it here or message us. Roland TD-30 and TD-50 modules are not effected as they started using newer easier to read and reliable screens in 2012-2013.
With the arrival and testing of the modules, REVERSE ENGINEERING was started, that is, the whole process took several months, between reading the protocol and analyzing how it forms the screen. Once this protocol was completed, research began to solve the speed problem. Because in addition to having the speed of Roland’s protocol, it would still have the protocol and display speed that replaces it. To solve this timing and protocols fight we have a microcontroller in the middle of the road that does all the heavy lifting.
We tested it on 3 models and it proved to be 100% compatible with the original Display protocol. Of course, as it is not original, we have a processing time to convert Roland’s protocol to a new graphic display, so depending on the function it may sometimes present a small latency or delay, but this does not compromise or affect its operation.
As Roland’s original Display is 5V, we opted for a 3V3 Display. In other words, we have an excellent resistive isolation between the module board and the board of our new DisplayTD-120.
With this isolation from the voltage conversion, we work 100% isolated from the Roland processor. And we can be sure that if any electronic problem happens, the probability of it being our Display is extremely low.
We offer a ONE YEAR money back guarantee against manufacturing faults and defects, but only when the display has been professionally installed. A claim will only be valid when supported by an invoice or receipt of professional installation from a suitably qualified electronic engineering specialist. If in doubt, please ask us before installation.
A very pricey, but necessary item if your td12/20 display is no longer readable. In the Netherlands a good used TD12 now sells for 400 and a good td20 for 500 and the x for 600 euro. Since I paid 350 euro plus for the display it is still cheaper than a replacement, The display itself is great, looks similar like my TD30 display. Overall a good buy, but it would have been nice of the cost would be cheaper for these old types modules.
1 Tip: In the installation manual it´s recommended to use 2 white washers to space bracket away from the bezel (cover window), But then the my screws were to short to get into the thread. I didn´t use the washers then, and it worked out too without crashing the display into the window cover. Just don´t tighten those 2 screws too much...
TD-20 even lets drummers add realistic snare drum “buzz” (the resonance created on the tom and bass drum) that matches the type of snare drum selected. It’s the subtle nuances like these that really make the difference during performance and recording.
Whether used live or in the studio, the TD-20 offers a host of powerful features designed to make life easy. Eight group faders are provided for adjusting the relative levels of each part (snare, kick, hi-hat, etc.), while 15 individual compressors and EQs let you sculpt each sound to perfection. The TD-20 also includes a
New to the TD-20 is a CompactFlash slot, which can be used for storing custom drum kits and sequencer patterns with optional memory cards. An expansion bay located on the underside means
there’s room for upgrades down the road. The TD-20 also features Roland’s V-LINK technology. Using an optional video editor from Edirol, drummers can trigger images or change cameras from the pads or kick.
Executing the Test mode on a TD-20 of system 1.xx while the TDW-20 is installed will delete the WAVE data stored in the TDW-20, making subsequent recovery
The system in TD-20 units of version 2.00 or later is not merely the successor of version 1.xx, but is a special system program for use in combination with the
