I am trying to source a green LED display panel ... 200mm x 200mm ... used in a roadside sign.
The part number is CST-U400-0808A-250C
I’ve spent hours on google and not found any reference at all.
The sign (10 years old) is double sided and uses 24 panels. Many have non working leds ... over 120 all up ... and because of potting, many can not be accessed because their connections are below the plastic frame of the module.
I probably will end up replacing individual leds ... but a source of new panels would be handy.
Thanks for any help.
