You can hear the sound of the show, means the TV's main board have no problem. The problem should be with its backlight inverter board. Just check it. Take a torch light, and light it on the screen, and see whether there is any picture on the background. You will see that, if the main board is OK. If so, concentrate on the backlight inverter board. It is common fault with most of the LCD TVs, irrespective of its brand. OK?
If you wish to get some details; check the sites linked here.

Lightening strike.....then 50" Insignia TV screen went black but you can hear it. Nothing will show on TV screen, not menu or anything!!! Help

If you can hear sound but no picture that means the Data Display Channel card is good and that there is hope to bringing it back to life.
Now LCDS use ccfl (cold cathode fluorescent) as the back light that means they are not lighting up; for some reason mostly the invert-er that steps up 12vdc or 24vdc to light the ccfl. Check if the invert er is receiving voltage if it is receiving but not stepping it up then the invert er must be changed. If there is light ,sound but no picture then replace the T-CON BOARD

you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

Turns on but will not display anything on tv no background or anything power went off yesterday but is on serge protector same as tv

Try a video reset:

While the PS3 is off (solid red led) hold down the power button until you hear the SECOND beep, quickly release.

Let me know if that solved your problem.

My xbox wont show on my tv,cant hear sound but no

It's possible that your Xbox is sending out a picture that's higher resolution than your TV can display. Try reducing the resolution of the Xbox video output.

Red light stays on

First before a reset the set must turn on, if the set just sits there with the red LED on you have further problems, so does the set display anything?
