If the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.

If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.

Audio is fine. Why did picture suddenly go black?


The board that controls the back light for the screen is called an inverter board. Sometimes, depending on the model , the inverter is combined with the power supply board. Go here to find the parts :www.shopjimmy.com

Hello,

The problem you are having is the power supply in the TV is failing. When you try to power the unit on you get on power or a slow turn on. It also can explain the problem of not running at full 1080p resolution because the higher the resolution the no power is required to operate the TV. Check out the article that explains the problem and how to repair it.

Picture goes out, comes back, sound is fine


I found several instances of this probllen on various forums, and determined that it is the bulb after all. It seemed that a bulb should either work fine or be burnt out, so I thought it might be something else, but so many other customers had this identical problem that I am 99% sure it is the bulb. I found a replacement bulb with housing for about half the price of the Sony Store, so i ordered it. In the meantime, another customer offered a suggestion to try adjusting the Power setting to Power Saving instead of Standard. I tried this last night and the picture worked fine! I will replace the bulb when it arrives and keep the old one on hand in case this happens in the future. Thanks to all of the posters out there!!!

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.

It was working fine then no picture dark sceen sound work fine


More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?
