The screen is black and won't take pictures

In what way is the screen broken? cracked, distorted picture, no picture but has sound?

If it is cracked. Replacement of screen is expensive. Cheaper to buy a new TV.
If Distorted. Parts linked to the screen can be the culprit. Most common part to fail is the T-con board. Main board may not be sending signal to the T-con board.
If its no picture but has sound. Back lighting has failed which could be several things that can cause that.

without any other details besides "broken" it will be hard for someone to help with diagnosing your problem. We need symptoms like. has sound but no picture. Picture has horizontal or vertical lines. part or half of the screen is black, black borders don't count. Hope the info here has, in some way, helped bring you closer to what to do with your TV.

The ysus board is the most common reason.

lubbarlubab, Looks like you will need to get a power supply repaired/replaced in your unit. Before you call out the service guy, you should spend 30-40minutes at YOUTUBE and view some "LCD-TV repair" videos and also videos of "LCD monitor repair" and LEARN what are the most common components that are causing this plague of "BLACK SCREEN of DEATH" to disrupt your life. If the "cold-cathode-fluorescent-lamps" fail to light-up due to a failure of a single or multiple $2 parts on a power supply board you have a black screen!! This problem is also very common to LCD computer monitors. Try to view a vid by someone called "cal22583" who did his own repair to a Philips 42" or 50" unit.

Really? Your lcd screen might be damaged! take it to someone who can tell if a pixel is damaged or not.

If you have sound, it means the LCD is either dead or the video firmware has locked up.

You'd hope it the firmware. To reset it, the easiest thing for you to do is pull the plug, wait 1 minute and replug it.

Didn't work?

Then the LCD panels are made by Quanta Display Inc. (QDI) of Taiwan. A common problem with cheaper LCD panels is the backlight goes out, so the screen is black but there actually maybe a picture there if you look close enough. If so, its likely a dead bulb. It will need professional service unless you know someone savvy with electronics.

My daughter is now going through two replacements for the screen going blank on this model. I'm still having to pay a deductible for a phone that was replaced the first time for the same problem this time. Evidently this is a common problem with this phone.

I have a black box that blocks my picture, Sharp flat screen

Clean everithing around the battery conections, try another battery too, check the polarity (basiks).
Try to use with the computer in webcam mode.
But dont try too hard if the common sence not workig, use the warranty!!!
