My 32 Emerson was working fine. today I pressed the remote to turn it on & only the Emerson name flashes on a black screen then quickly goes back to black. Any idea on this issue?

look on the Dish Remote for Format button , should be on you bottom left..

press power screen reads digital television then the power light and stand by light turn on then screen goes black

I had this problem with the LC320EMX, after extensive searching on the internet, I found a solution. The TV has entered some kind of test pattern, to escape from the flashing color test pattern do the following:
While the screen is changing from red,green,Blue,White, & Black, and is Unresposive, Take your factory remote, Press the up arrow, then the down arrow, then (ON THE TV) press the power button. Turn the set back on and it should be functioning properly. (BTW: the set gets into this test pattern if you press too many buttons on the remote, or if you use a universal remote with the wrong code)

last week i had an emerson 21 inch with built in dvd.,it was flashing colours.none of the front buttons would work.i unplugged the front buttons and plugged them back in again.set is working fine.ican not remember if i did it with the power on or off.try both.some how the front buttons were locking up the micro.

i install uverse, the auto seek is done by hit and hold TV and OK. wait for lights to flash enter 900 and push play over and over SLOWLY and when the tv turns off, press enter.

NOTE: some tvs WILL NOT program to our remotes

one of the floresant bulbs has fail there is a place in Haverhill Ma called Tops Electronics that can fix you up really quick but you will have to ship it to them they do good work there
their new name is pinnacle solutions group over 30 year serviceing

I have a 32" Emerson that did the same time.
The problem with mine was one of the Power Inverter Transformer when out. It used 6 of them to power the LCD screen.
I believe yours will have more than 6 since it's a bigger screen.

The Power Inverter Board is all one piece, the best place to get one at a good price is Shopjimmy.com

If the power indicator remains on (or LED remains green) when the unit goes dead, you will need to replace the main board to resolve.

TV worked FINE for the past 2 yrs---this morning we woke up and the screen is totally BLACK! No sound..nothing. REmote doesn't do anything to the TV. Red light says ON unless we unplug it. Remote won't turn off the TV.
Any advise? Picture tube??
Worked great w/out any problems until we woke up today!

Thanks,
Tina

i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel
