The power outage that hit a Corning Inc. (GLW) LCD glass manufacturing plant in Taiwan over the weekend is expected to hurt the company's results, but not interrupt flat-screen television availability during the holidays.

The liquid crystal display panels that Corning made for the Christmas season were already shipped to television makers like Sharp Corp. (6753.TO) and Samsung Electronics Co. Ltd. (005930.SE), said Corning spokeswoman Kelli Hopp-Michlosky.

Corning expects a "material" hit to fourth-quarter LCD glass volume, which is now expected to be flat to slightly down in the period. Before the incident, fourth-quarter glass volume was expected to have risen as much as 5% sequentially.

The impact from any product shortages would be felt in the middle of the first quarter, around February, Hopp-Michlosky said.

Sales of TVs and other consumer electronics are already seeing a stutter in demand. Best Buy Co. Inc.'s (BBY) fiscal second-quarter same-store sales fell 3.1%, hurt by a plunge in videogames, music and movies, and by ongoing price declines for TVs.

Corning's power problem caused the shutdown of several glass melting tanks and the company said it is in the process of determining how much capacity was affected and how long it will take to repair the tanks.

Corning shares were recently up 10 cents, or 0.7%, to $15.47.
