How long have you had the set for and when did the problem occur?
Was it after a storm or power outage?
When it shuts down are there any blinking lights on the front of the TV?
about a year and it happened this am I watched tv until about 10 pm last night no problems and this am when I turned it on I had sound only. after messing with it I was able to get nowhere then went to work. when I got home I tried it again. At some point and I don't really know what happened it found my PC and alerted me so I could read on the screen then I moved the inputs to HDMI1 where my cable is and the weather channel came on with full screen and sound then it all went away
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
yes problem still exists. should the red light be on or off when the power is on I can't remember
If the TV still does not power up, then there is a short inside the set stopping it from fully powering up.
It is most probable that there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.
The capacitors are located on the power board inside the set, where the AC cord plugs into and can be replaced by a Tech for no more than $200 parts and labor.
Unfortunately there is no sequence of buttons or reset you can perform to get the set working again. Do you have any experience testing live voltages, or soldering on electronic equipment?
If not, then I would suggest using the link below to locate a technician in your area:
If you need further assistance, let me know.
If you press Volume, Input, or any of the other buttons on the TV does anything at all come up on the screen?
it is hard to tell but i dont see anything my flashlight is not the best and it is like a mirror reflection
The problem I indicated above is what is wrong with your TV. If nothing comes up on the screen then the set is NOT fully powering up- meaning that the backlight inverters, or the panel itself are not powering up. There are no settings on the TV that will prevent the Volume, Input or MENU functions from coming up on the screen and this indicates a problem with the TV as I stated above.
