Thanks for the info.Does power light blink contentiously or is there any pattern like 2 times slow blinks then 5 times fast blinks then pause for few seconds and repeat the blink pattern? Flashing power light is an error code and I'm trying to get that error code which will help to diagnose the issue.

Thanks for helping me in troubleshooting, this kind of problem occurs due to failure of EEPROM (memory) chip on main board of TV, EEPROM chip stores TV firmware (internal software) data and bad EEPROM chip isn't allowing TV firmware to boot up so it get stuck. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.If TV is out of warranty then you would replace EEPROM chip on main board which is available at following supplier for $15 or replace entire main board in TV..http://www.shopjimmy.com/sharp-lc-39le440u-9jy0139ctj01100-main-board-u3102-eeprom-only.htmhttp://www.shopjimmy.com/catalogsearch/result/?q=LC-50LE440UIf you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...http://tvrepaircanada.com/I trust my input will help you out.
