The maker Viera TV also announced that it would book a massive $9.6 billion net loss this fiscal year, as it undergoes a major overhaul of its troubled business. The company also said, though it will achieve an operating profit, restructuring costs and write downs will ultimately result in a 765 billion yen shortfall. For the six months up til September, the company’s sales of flat-panel TVs, digital cameras, and mobile phones tumbled, while sales of refrigerators and washing machines were encouraging.

“The global economy continues to contract with much deep remaining uncertainty, due to the European financial crisis and slowdown of the Asian economic expansion, including China,” the company said in a statement.

Panasonic Corporation (NYSE:PC) (TYO:6752)  also warned that a territorial dispute between Beijing and Tokyo, over East China Sea island chain, could also hit sales by $1.25 billion, as angry Chinese consumers neglect Japanese-brand exports. Moody’s rating, downgraded Panasonic Corporation (NYSE:PC) (TYO:6752) last week, cited weak profitability and high debt.

Apart from the competition, Japan’s electronics sector has also struggled by the rise of the yen, which makes its products less competitive overseas. The yen hit a record high around 75 on the dollar late last year and remains strong. The company’s rivals, like Sony Corporation (NYSE:SNE) and Sharp Corporation (PINK:SHCAY), which announced their earnings this week, have struggled in the television segment amid falling prices and stiff competition from overseas rivals. Japan’s Toshiba Corp (TYO:6502) (PINK:TOSBF) and Fujitsu Limited (PINK:FJTSY) slashed their full-year profit forecasts on Wednesday.

This year up till now, shares have dropped more than 20 percent, compared with a more than 5 percent gain in Tokyo’s benchmark Nikkei 225.
