Do you have a coaxial cable attached to the antenna in on the TV? The TV has an ATSC (digital OTA) tuner and a NTSC (analog OTA or CATV) tuner. The initial setup wants the incoming antenna in signal to be present (this is the only message on the front of the TV manual).
Hello; I am John at J. D. Electronics, Poland Maine. This problem is usually caused by defective inverter transformers. These sets are made by Funai Corp. I have now replaced 100's of these. They are about $5 each and most sets have 5 to 8 of them. Replace them ALL at once. There are many other problems I have found that require replacing whole PCB's , so this is only a guess. John
This is Emerson's #1 problem.
The Inverter Transformer on the power supply/backlight inverter board goes bad. It's what powers up the screen for your TV. When the part goes bad, it doesn't have enough juice to power the screen and the TV automatically turns off. You have 5 Inverter Transformer on your board.
You can fix the problem by replacing the whole board or replace the bad Inverter Transformer.
Here's where you can get a new board for a good price: http://www.shopjimmy.com/catalogsearch/result/?q=lc320em9+inverter
Or, here's where you can get replacement Inverter Transformers:
Is it under warranty by chance?
What is happening is when you turn on the TV, it's trying to power up the screen at that moment. If it can't power up the screen, it will turn off automatically. This is what they call, "Protection Mode".
All the TVs made by Funai (Emerson and Sylvania) are having the same problem. The Inverter Transformers needed to power up the screen are somewhat low quality and burn out easily. I'm sure of of them burned out.
Your TV, I believe, takes 6 of those things to power the screen. And they are all on one circuit board.
If the TV is not under warranty, then let me know what the board number is on that circuit board. The board inside the TV should have maybe 6 connectors that hook up the screen. I may be able to track down a replacement board for you.
Give FUNAI a call they can walk you through the problem. There info is... FUNAI CORPORATION Customer Service Tel :1-800-605-8453 http://www.funai-corp.com
The failure with this LCD might be due to a failing power supply or backlight inverter board. Since your TV is less then a year old, I would suggest to call the manufacturer to get it fix under warranty.
Good Luck.
Hi, I just fixed one I bought on eBay with the same problem. My problem was caused by the screen backlight inverter. Fortunately I had one from another TV I bought last year on eBay. The repair only took about 15 minutes. Your best bet is to contact Funai Corp. and really complain even if it is out of warranty. They make Emerson, Funai, Symphonic and Sylvania and all the parts inside are the same (from the same years). If that don't work look on eBay for one with a broken screen or some other damage, call your local dealer and see if they have the inverter from a broken TV or ask around. We have a freecycle group in Michigan that recycles things rather than throw them in landfills you may have one in your state too !
Good Luck,
