The LCD panel is bad.

Clean the connectors from the main to the Tcon along with the flat cables that go to the panel, next would be repalce the tcon board,if that doesn't fix it you may have a bad panel

They are fairly easy to replace. If you can replace a headlight on your car or a hard drive in your PC you can do this. Lay the panel face down on a large surface covered with a blanket or cloth. (make sure nothing gets between, glass will crack)
There are screws, that you can visually identify, to remove the back panel. Once screws are removed, lift back panel slowly. Sometimes wires are cable tied to the rear cover.
Look close to identify the board you need to remove. You should keep track of cables that you unplug and where they go. If you lose track of one dont panic, most are keyed. Pay close attention to the connectors and how they work. Some are very tough and some are not.Pressure connections are easy to break. This type holds data cables that look like small ribbon cables.
Good luck

Can be downloaded from samsung.com . Just type in name and model in search and scroll down to manuals.

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having. If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors pictures: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.

I had the same problem. http://www.youtube.com/watch?v=tK7zFBBU6p4&feature=related We're not alone - its a common problem with Samsung. I watched a few of these and was able to see the bad capacitors, de-soldered and replaced them for under $5.00.

INVERTER PANEL ON BACK OF LCD SCREEN FAULTY REPLACE

AVERAGE REPAIR COST £80 TO £100

try ebay

Call 1-800-Samsung to set up a warranty service call. They will repair it in your home if they send a Samsung Field Engineer. You probably have a bad Main bd.

First thing to do is to hook up a DVD player or a External Antenna and see if you can get a picture with sound. This will isolate the tv from the computer. If you get a picture then the fault is with the computer. If you cannot get any picture or even the OSD (On Screen Display Menu) then you either have a bad Main bd or a bad T-Con bd.

WHAT THAT MEANS IS UR TUBE IS DONE U CAN HAVE IT FIXEDWITH A REPAIR GUY BUT IT WII B ONLY A MATTER OF TIME TILL IT GOES OUT AGAIN BUY A NEW TUBE 4 IT OR JUST GET A NEW 1

seems like your remote is getting bad and also a keyboard control board from the TV,
whats the model number?? maybe I can give you the part numbers for it

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

What would cause that is failure of some part (probably a filter capacitor) in the set's power supply. The usual cause is component stress due to manufacturers keeping their costs down by using parts that just barely can stand their operating voltages. (Higher rated parts would last longer, but would cost more.) Some parts are just a little too weak and break down. It's not unusual to have this kind of problem these days. The set would be repairable unless there was physical damage to the circuit board itself. You might have it looked at and get an estimate for the repair.
