Have you tried a factory reset? I had a similar problem my TV was stuck on standby (red light only) I did this

1. Turn on the TV.
2. Wait approximately 40 seconds for the TV to completely start up.
3. On the TV remote control, press and hold the UP ARROW button

and it worked!

Is the tv signal originated from cable tv box? Or a antenna?

hi,
After factory reset all the settings of the tv will goto factory default. To get the video again you have to auto tune the TV. For the go to the menu and select setup then select Auto program. Wait till the auto tuning end.
OK

Reset the tv back to factory setting,by unplug,repluging it an hour later.Go in ur tv AUDIO setting reset it,now it back to factory setting,Should work,not than the tv Tuner board recieve the broscast signal boad is have problem must br replaced.

Try to use the reset factory reset feature. Unplug the set. After unplugging press the power button for 30 seconds. Plug the set back in and turn it on.

Try 2 things:
1. If you have a cable box with the yellow/white/red outputs, use a compatible cord to run the 3 to another input on your TV (ie input 1 vs cable). and/or
2. Do a Factory reset. Hold the "menu" button on your TV then on your remote hit "menu" then "8" then "select" and go to "factory reset". You may have to unplug the TV as it may freeze on "factory reset". Replug it then try it out.

Hope it works.
