Scheiber Panel Display

[leehadjiosif]

I'm looking to source the LCD display for my Scheiber PCB. I don't want to buy the whole board (yet) since I verified that I can replace the display only. If anyone knows of a source I would appreciate it. I searched many different ways with no luck. The display is about 6x4.5 cm and connected by a ribbon connector. See attached pic.



Thanks.

Trying to locate a replacement display for a friend. Display looks to be manufactured by tianma.

Any help is appriciated.

Thanks!

I think that you are correct and it is probably a Tianma TM12864G3CCWGWA FP-1

I'm not 100% certain but that's the code I wrote down many years ago. I decided to make a replacement board when mine blew years ago. The screen was the hardest part to source as it had to be serial, transflective, approx. 58x29.5mm viewing area and mounted on a board able to sit between the mounting points.

At least your job is simpler as your board still works.

I eventually settled for a parallel unit and used 2 arduino UNOs. One for screen and second for IO with serial communication. The display wasn't great and I decided to replace it with a better screen. It wasn't any easier second time around and I gave up on finding a perfect match.

I found a pair of touch screens (2.4" & 2.8") bundled with an arduino UNO on eBay for about £7 and decided they were so cheap I'd use the 2.8". I'm still working on it but the full colour display looks good and I'll probably replace my MkI twin Arduino version. The display is parallel and not transflective but I'm using a single ESP32 and have plenty of pins. I may also link the display to my cheapo eBay Bluetooth enabled battery Ah/Wh/V meter.

I was having same problem, my display slowly died and was too feint to read. Thanks for the help from Mistroma and VirtualBurton got me on the right track. 

With the help of the part number, found the product in China and speedy delivery had it within a week for $60usd w/shipping. I was able to solder the old display out, new one in and was careful on alignment, attached ribbon. Bingo, plugged it in today and works and fits perfect.

Thank you, I found it very helpful and I purchsed the lcd display as you have done. My only problem is on how to soldered out the old display. On the back there are four points where it seems soldered but even if I tried to solder out these point the lcd display stay fixed on the board.
Could you please let me know how did you do?
Thanks!!!

I'm afraid it's been several years since I removed the LCD. I was pretty certain that my board had been fried by an electrical spike. I couldn't source a replacement at that time and built my own from scratch as I thought the board was also dead.. I can only remember de-soldering 4 lugs holding the display and they just held it in place with no electrical connection. The signals, power etc. came via the small ribbon cable and that's easy to disconnect. No solder required there.


I think the solder bleeds through the holes and grips on both sides. I'm pretty certain that I just used a decent solder sucker to remove all excess solder. I vaguely remember doing that and still having to work around the holes in sequence a few times whilst levering the board up slightly near each corner at the same time. The combination of removing excess solder and gently lifting the corners in turn should work.

Perhaps someone else has dismantled the board more recently. I'll still have a look for the old board tomorrow to see if I can spot any other connection points.

Thank you! Any other suggestion would be very much appreciated!

I managed to find the old PCB. I can only see four mounting points and the ribbon connector.

The LCD board should come off if you can remove all the solder on the four mounts.

Not sure if it helps, and not trying to self promote, but I have my used one that I removed for sale if that could help. It’s the full circuit board with the display, everything was working when I removed it.

I replaced most of the DC control with digital switching and CZone on my boat so I don’t need it anymore.

DM me if you have any questions.

Thanks,

Hey Guys, I'm in the same boat. ha.

When I bought the boat, the LCD was in a bad state (but it worked!), warped as if it was in a fire.. Kinda strange. Anyway, I proceeded to get the LCD only from eBay and put it on and was a happy camper, but 24 hours later it was super dim, and 48 hours later it was impossible to read. I have no idea what is going on.

So I bought another LCD only but however, this immediately didn't show. So I'm out of pocket $120 and no solution .. (but I have two LCD's! In case anyone needs - I'd give them away free, PM if need be)

So I tried to source the PCB however there seems but one company that sells them and they showed having them In stock on Saturday, however, when I asked a question about it it is not listed not available.

Does anyone know where to get one ?

Or can I order "THE CUSTOM VERSION" from Mistroma? (I'll PM you)

Thanks everyone.
