First of its kind in the region, the state-of-the-art display covering the western wall of the new WGBH headquarters debuted amid fanfare last year, when it began beaming an ever-changing array of images … But after generating lots of talk, and some distraction for passing motorists, the screen went dark five months ago.
WGBH, the public broadcaster responsible for the award-winning science program “NOVA,” has been stymied by a technical glitch. The television and radio station turned off the 30-by-45-foot LED display in June after it carried a pockmarked image of Big Bird, the last in a series of pictures marred by dark spots, caused by diodes that switched off when they became too hot.
Now WGBH is suing the installer and manufacturer for breach of contract and failure to honor the warranty for the massive display, known as a digital mural, which was supposed to be visible for 1 1/2 miles.
