I have an Emerson LF461EM4 that won't power up. A red light comes on but that is all. Any ideas?

Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
I need additional info to troubleshoot the issue.

- Does the power light turn function according to push power button?

- How old is the TV and how long it have had the problem?


Customer: replied 7 months ago.
Power light comes on when you plug unit in. Doesn't change when power button is pressed.
Not sure how old unit is. Belongs to a friend.

Thanks for the info, it seems main board internal failure and most probably EEPROM chip has failed that stores TV firmware data (TV internal software) which isn't booting up so nothing appear on TV screen.

Please replace main board of TV which will help to resolve the problem, check with following supplier link to get replacement main board or search/google it to get better price and stock info..

I trust my input will help you out. Please feel free to respond if you have any additional questions.
