the backlight is either going out or the capacitor for the backlight is bad to where its not storing enough power to run the backlight the start capacitor must be good but the run capacitor might be bad usually the backlight itself goes bad but not if it turns on for a few seconds it would have to be the capacitor.

is there any picture at all ? if no signal message regardless of any signal input , ur ad board need to be change.

Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

it either needs new front switch panel or new signal module, turn the tv on and disconnect the front switch board if it quits doing things on it's own you need a new front switch panel, if it still does functions on it's own you need a new signal board.

I presume the back cover does not really open from the back or if it does you cannot see the speakers from the rear?which if you cannot see them with rear cover removed leaves two possible paths, the entire panel unit with the screen has to be removed and they are under it OR the entire front may be snapped together and has to be pryed out (if you see a seam or crack like area running around the side up front get a thin metal putty knife and try to open it, seen a lot of computer LCD monitors where they come apart from the front--and are snapped together much like some of our plastic remotes--have to go in from the front and not the rear.Do some careful looking to see what you have.

Hi SgtHoagie and anyone else:

I ran across this problem too, at 1:30 this morning. At that time I had to get out of bed and try to figure out what the hell happened. It seems that my flat panel TV somehow got switched over to the computer monitor mode. When this happens, the light will turn an amber color. On the bottom of your flat panel you'll see some very small buttons, marked "MENU," "CH" "VOL" and "SOURCE." You'll want to click on the "Source" button and that will switch your flat panel back to the TV mode. Your flat panel TV can also be also used as computer monitor.
