Genesis Microchip ( GNSS) shares plummeted after the chipmaker said its fourth-quarter revenues will come in below its previous guidance.

Analysts were looking for earnings 15 cents a share and revenue of $65.3 million.

The company attributed the shortfall to weaker-than-expected demand for flat-panel television controllers in Europe and for digital CRT TV controllers in China. Genesis Microchip said lower-than-expected yield on one of its newly launched TV controller products hurt gross margins, which are expected to be 43%, below its guidance of 46% to 48%.

The accounting charge, related to LIFO accounting, is estimated to be $13 million to $15 million, compared with $6 million a year ago.
