Synscan screen

[Anthonyexmouth]

Does anyone know if it's possible to get a replacement screen for the v4 synscan handset. A now ex friend just broke my screen. I never use it but it's bloody annoying and if I can fix it I'd like to.

Pragmatically: Wait for some time for a 2nd hand one to come up here or on Astrobuysell - they are 50 - 75 pounds. Looks unlikely that the parts and work are cheaper.

Astroboot have several handsets for sale at the moment, including a V4

thanks but really want to find a broken one with a screen i can salvage or get a new screen. seems stupid and wasteful that i cant fix this one for the sake of what is probably an off the shelf lcd screen worth about £1

Fine if you can manage it, but I suspect that the 'screen' doesn't just unplug or unscrew, and to change it you will need specialist surface mount desoldering/soldering equipment that will cost more than a replacement handset.

No, just a ribbon cable, that's what makes it a frustrating waste if I can't get another screen.

Is there any identifying mark on  back, maybe AliExpress would have it ?

blank on the back and numbers on the front don't bring up anything on a search

Hmmm, now you are asking..I honestly cant remember, but thought it was less than that, and it should be less really... 

[Anthonyexmouth]

Yeah, can't imagine any takers at that price.

It looks like a basic 2 line LCD module, but the 30 pin connector is confusing me a little.
Visually very similar to ones like https://www.alibaba.com/product-detail/1602-16-Characters-2-Line-LCD_60758385192.html?spm=a2700.7724857.normalList.78.bd9048604VZ0Uu

but unless some of those pins are shared I can't imagine what the difference is?? All the ones im finding are 15 pin

 

[Anthonyexmouth]

Found plenty of 30 pin. But nothing as yet in the right form factor. I don't think for one minute that it's a bespoke display. I wonder if the screen is the same in other versions. 

Hate to lose this for the sake of a £1 screen

[Anthonyexmouth]

Just checked the numbers on the back light but no luck. 

[upahill]

I thought it was a character LCD at first, but actually I think its a graphic lcd panel, which would explain the extra pins.

I have had some success in the past asking manufacturers to help identify components. I would start by seeing if something like this matches the physical dimensions of the LCD you have. Then get in touch with that supplier and see if they can identify compatibility / alternative options from your pics.

I imagine that the pinouts are going to be the same across similar screens, and believe there is no embedded controller on these so may be worth a punt for a few $?

 

[Anthonyexmouth]

Be a bit of a win for a few people if a screen can be tracked down. In my search I've found a few posts of people with broken screens but only the usual result of suppliers trying to flog a new handset

[Rob Coleman]

I'm in a similar position - I have a v4 handset with a damaged FPC cable. I was hoping that I could replace the LCD with one from an old v2 handset but didn't realise that the v4 has a 30 pin cable.

Looking at the part numbers on the LCD, it seems that it is an unusual 144x33 graphic display. The only one I can find with this resolution is here: https://www.made-in-china.com/showroom/jerry22520/product-detailJXqxAaKChzhB/China-Graphic-LCD-144X33-Ktg1443301.html

I think my only option is to try to repair the FPC with some fine gauge wire...
