In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

My 32-inch lcd tv from sharp has no picture but audio works fine. No picture ever comes up, not even the "please wait" message. Whats going on?

My 3 year old Sharp LC-40C32U would start up fine but within a minute would go dark (audio continued fine). For a while I could turn the set off and on again and it would be fine, but over time this became less effective. My solution, which has worked for a week now, was to a) unplug the set's power cord; b) after 3 minutes plug it back in and turn the set on; c) on the remote hit MENU and slide over to SETUP (3 clicks to the right if the screen is dark) and one up to RESET; d) hit ENTER and follow the prompts. This puts the set in it's factory configuration so you will have to rescan for channels. Worked for me.

Sharp Aquos LC-32D41U pictures problem

I have had exactly the same problem. Sounds daft but by not using the remote, and only using the power on/off switch on the TV itself, it is working perfectly...no idea why
Use the remore for changing programmes etc but not for on/off
Try it anyway because I know how annoying this is

Sharp Aquos LC-32D4OU

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

Sharp aquos 32'' LCD

Dead pixels are a fact of life on these newer flat panel TV's I dont believe you can fix them. They will be "on" on a completely black picture.

Sharp Aquos LC-32D40U-picture goes off at random times

The bad news,your set needs a new inverter board installed.With persistence to sharp,you might be able to get them to pay for the parts.
