Chirping Non-Responding TV - Cody on November 14th, 2016

50" Emerson screen went blank and began chirping. After doing research I determined it was motherboard. Purchased new motherboard replaced, and now TV works like new.

Beeping TV fixed LF501EM5F - Gregory on September 13th, 2016

TV would not turn on. No lights or anything. Just a Beeping sound coming from the power supply board. After research, tested everything on power supply board. Everything tested good, purchased a main board. Replaced in 10 min and worked great!!!

if at first you don't succeed - Dan on August 29th, 2016

I have an Emerson 501 and it had a blinking red light and would not respond. I tried the small IR board (web said to try) and no change. Replaced the control board and we're back to normal. $79 fixed a $500 TV and it was so easy.

I'm one of the Walmart Black Friday victims on a 50 inch Emerson. After 6 months the TV would not turn on. After going thru 2 boards and the help of a tech named Chris, my set is back working and my insurance paid for it. Thanks ShopJimmy.
