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.
I'm having the same problem and the television is not even a year old. My model # is LC32D47U
What is the model number of your TV? Is there any backlight, can you see light behined the screen?
When I asked you about light behind the screen I meant if you can see screen kind of glowing in the dark? In case that you can see backlightbut can not see a picture you will need an LCD CONTROL UNIT. If there is no BACKLIGHT, you need to replace BACKLIGHT INVERTOR UNIT.
Your main problem would be getting BACK LIGHT INVERTOR for that model. LC26D40U is not really a Sharp TV, it is build by ORION, that's why Sharp never had INVERTOR or LCD CONTROL available as a spare part. But, there is always another way to get parts. Places like Ebay,craigslist ETC.. If it worth it or not, I guess up to you.

This tv's model number is LC26D40U. I cannot tell if there is light on the back of the screen. I have taken the back cover off but don't know exactly what to look at. Help? Suggestions?
Any ball park figures on what a backlight invertor unit would cost to have a tech fix in US currency?
