Feb 20 (Reuters) - Electronics and home appliance retailer Conn's Inc cut its profit forecast for the current financial year, citing higher bad debts and weaker sales growth for televisions and other electronics.

Shares in the company, which offers credit to customers, fell 19 percent in premarket trading.

Woodlands, Texas-based Conn's said delinquency and charge-offs rose in December and January, leading to an increased provision for bad debt in the fourth quarter.

The company reported weaker same-store sales trends in electronics this year, in part due to higher prices for many televisions as suppliers cut back on promotions.

Conn's operates 79 stores in Texas, Louisiana, Arizona, Oklahoma and New Mexico.

For the year ending Jan. 31, 2015, Conn's forecast earnings of $3.40-$3.70 per share, down from a range of $3.80-$4.00 issued in December.

Analysts on average expect a profit of $3.96, according to Thomson Reuters I/B/E/S.

For the fourth quarter ended Jan 31, 2014, Conn's said it expected adjusted earnings of 75-80 cents per share, far below the average analyst estimate of 93 cents per share.

Conn's estimated net sales of $301.6 million for the fourth quarter, below analysts' estimates of $361.5 million.

Conn's shares traded at $45 premarket. They have risen about 75 percent in the past year to Wednesday's close of $55.80 on the Nasdaq.
