tft touchscreen lcd replacement

[VoltDaBolt]

I would highly appreciate any help in resolving this. I have a damaged 5 inch tft touchscreen display (800 x 480) Dot-matrix LCD (128x32)(6) screen that needs to be replaced. Unfortunately I am unable to find any more information off the assembly. I have spent days trying to find the right replacement however I could use some help. Please see the images for details. Thank you.

Hi VoltDaBolt,

welcome to the forum.

By the looks of it, it is an assembly of a front glass panel, the touch panel and a display, to which I doubt you will be able to source a replacement, unless it is from a device made by a reputable company with a replacement service.

Maybe if you provide us with some additional information, someone is able to tell you more about it.

There seems to be some writing on the metal backside and on the front panel that might give a clue, but can't be read from the photos.

Thank you pcprogrammer for the information. Yes, there is the touch panel and the display panel. It came out of an instrument, I already have contacted that reputable company, and they offered 20% discount on a new instrument when the old one is returned to them. It is quite frustrating to hear that however I am on a mission to find a workable solution without having to spend another $1400.

Thank you.

What I did with my cheap scope that had a defective touch panel was to look for both separately. Unfortunately I broke the glass panel and ended up making a thin acrylic replacement for it.

The touch panel looks like a capacitive one with some GT chip on it. The display who knows. Is it really broken? If it is only the glass and the touch panel are busted it might be easier to repair.

Aliexpress does have lots of displays and touch panels, but it might be a bit tricky to find the right one.

would be nice to know  wich reputable company you talk,    being cryptic  doensn't help

and take a photo of the flexible touch panel  ending  and you have some model numbers on the lcd back plate ....

if its a 4 / 5 wire  etc ....in some cases its or could be an usb interface ... you have tons of models availble  on fleabay just take the diagonal measurements ... 

sometimes its a glass under the lcd touch surface,   in this case  it seems to snap on top of the lcd

we see some numbers  under the touch section ..........

To get help you should tell from what device model it is and post photos of all numbers present on the display. You did neither. How are we supposed to find a replacement for something abstract?

[wraper]

Also there appears some model number on the touch, maybe separate the display and post a photo. BTW I guess initially display was working and only touch was broken. When they are not glued together and there is only a foam adhesive around perimeter that holds them together, usually they can be replaced separately. But it looks you have destroyed the display too.

It also looks as if the display cable has been cut with a pair of pair of scissors. If so show us the rest of the cable. There might be a number on it, or at least show how many pins there are.

It could be 50 pins, 40 pins or any other number of pins.

The display is most likely fixed with some double sided tape onto the touch panel. The touch panel is most likely fully glued to the glass pane. There are special cutting wires on the market to separate them from each other, but I can't recall a name or brand. Someone wrote about it in the same thread I wrote about the acrylic replacement.

My apologies for the missing info, I needed to get the info from my kid who is away at school.

Instrument: Synthesizer
Make: Roland

I have taken some detailed pictures however this forum has upload size capped and I am unable to upload the images. I will  try to host these images somewhere else and then share the links images can be viewed in full details.

That is only the display. Means he still has to source the touch panel and a replacement for the glass.

There are utilities to reduce picture sizes. On linux gthumb is easy to use.
A problem with referring to pictures on some hosted environment can break the post over time.

Are you sure that the FA-06 has a touch panel?  To me, it looks like a piece of glass to protect the LCD.  It looks like the glass is a long distance to the LCD.  A touch screen would be bonded directly to the LCD with optically clear adhesive.  The photo just doesn't look like a touch screen to me.  Of course, I could be wrong since I have never seen one of these instruments in person.

Not necessarily. In the sandwich I encountered in the FNIRSI 1013D the touch panel was bonded to the thicker tempered glass with a clear adhesive. This combo was then attached to the metal rim of the display with some double sided tape.

The second photo in the original post shows a wide flat cable with a chip on it. This could be a clear indication of a capacitive touch panel.

To make sure a lot of pictures of both the display/touch panel/glass sandwich and the hardware inside the FA-06 can help a lot. Like for instance a closeup of the chip on that flat cable.

I took a quick look at the FA-06 manual and looked at a couple of youtube videos in operation and there is nothing that indicates that this is a touch screen.

I do agree with you that it looks unlikely to come from a Roland FA-06, by just looking at the front panel of it. The section with the display looks like a single panel with cutouts for the buttons and the rotary dial.

The Roland FA-06 does not have a touch screen.

I bought an official Roland FA-06 LCD just over a year ago, so they probably are still available.
