Broken flat screen

When the LCD panel is broken, you should consider the TV 'Totaled". The cost of a replacement LCD screen is almost as much as a new TV. You can sell off the remainder for the set for parts and recover some of your investments to buy a new set.
You can search the .net for a TV armour screen to prevent this from happening again.

Samsung LCD tv - Turns on and off by itself.

Since you have another TV with the same problem you can try using an antenna(indoor model ok) to see if the cable is causing the problem. If not return TV before the warranty expires.

How do I troubleshoot my Samsung TV? I have sound, but no picture.

Caps can fail with no outward signs. It takes a special meter to test them. Your set may have a back light inverter that powers the back lights. When it fails, the picture cant be seen, but you have sound, to check this look for a picture on the screen using a flashlight

Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel.

Contact any service technician. The circuit will differ with models and versions.

Why dont i have a picture?

Hi, not sure if you have the same fault as i had, but our tv only had half the screen go off, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps jim
