Hey guys, I have a Sharp Aquos LC37D43U. This morning I turned it on and I got a brief picture (a millisecond maybe) then nothing but sound. I tried a dvd and again nothing but sound, no picture. I unplugged it for the day then rebooted it and it's still the same.

When I asked my daughter she said that last night she was watching tv and the picture just went out. She turned it off and back on and she got the same, no picture.

Any ideas?

Silly question, the input wasn't mistakenly changed? If not take it to the nearest repair shop.

How loud are you listening? How big is your room? Did you calibrate the TV? Do you have an SPL meter?

OK seriously, sorry... no ideas Rick, I was going to say unplug it for awhile...hope you figure it out man.

Hello wid,

How old is the t.v?
Can you get any of the on-screen menus to appear?

It seems the backlight on your LCD might need to be replaced?

Is the t.v covered by warrenty?

Good luck

When I was a kid I never admitted to my parents when I broke things either \:\) .

I did a search for you and found others with the same problem and asking for help but no responses other than contacting Sharp. I had to call them about my Aquos and they were pretty good to deal with.

Good luck

I bought the tv in March of 06. My wife insisted on an extended warranty so we should be covered. I am just curious if anyone had any other ideas.

I can't get to the menu at all, it won't bring up anything on the panel.

The inputs are ok or there would be no sound. No?

When you say you rebooted it, does that mean you tried "system reset"?

One other thing to check. On my Aquos remote there is a button that says "audio only", if it's on your remote also, maybe it accidentally got pushed and that's why there's no picture.

I tried what I found on line as a system reset.

I found this "The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem"

I did the flashlight trick and can see video so I think it might be the back light problem.

The spec'd backlight life for that particular LCD is 60,000 hours. I would guess your backlight has failed and will need to be replaced. It fits the symptoms.
