Several incidents of overheating have been reported in the United States, but Philips said materials used in the television sets were all flame retardant and there was no risk that they would catch fire.
"As a precaution we'll go to the consumers and replace the component. There's no fire risk," a Philips spokesman said.
He declined to say how much the house calls would cost the company. Philips would approach consumers individually and had not issued a press release.
The problem occurred in 42-inch and 50-inch (127 cm) sets. It is restricted to the United States, because the faulty capacitors involved are used only in the assembly lines for the U.S. market.
Philips this week confirmed to Reuters that it could not meet demand for its flagship liquid crystal display (LCD) flat TV sets, due to production problems involving high-quality display panels from its key supplier LG.Philips LCD, a joint venture between Philips and the Korean conglomerate LG Group.
It said it expected supply would meet demand in April.
LCD and plasma are different technologies and are the two main flat-panel displays systems used in thin television sets.
Philips is the world's biggest lighting maker, a top three hospital equipment maker, Europe's biggest consumer electronics producer and the region's number three in semiconductors.
