Mine was doing that then it quit even turning on just like yours so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

Problems can often occur with even relatively new Samsung LCD, LED Television. Some customers report their screen going black shortly after turning on the television, and flickering picture even though the TV's speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect.
First, check the input settings of your television. Often, users will experience a dark screen when first turning on their television if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player. If the problem persists, try reconnecting all cables on the back or sides of the television. It's possible that one of your cables has gone dead. If you have access to other cables, try swapping these in and see if the problem persists. Some customers report that turning the television off and unplugging it for an extended period of time, up to 24 hours, can fix the black-screen issue. Samsung TV - Power Supply Issues If you've tried all of these suggestions and problems persist, it's possible that the power supply inside the television is defective or broken. The power supply for most Samsung LCD, LED televisions will cost around $150, with labor costs of around $250. Unless you have a fair amount of TV repair expertise, this is probably not the sort of repair you'd attempt yourself.

Hi i have a 42" LG lcd tv .When i switch it on


the inverter for the backlight likely has a bad capacitor or more. The fluctuating high voltage is causing the jumping and eventual blackness until sufficient charge is on the caps, at which point it stabilizes...it eventually will stay black unless the caps are replaced.

I have a 42" LG LCD TV and just experienced this today. Watching cable, then the screen went to black, but audio continued. I pressed the guide button on my remote and pic came on with my guide menu. But then went to black again 10sec later and has remained that way for nearly an hour. Tried switching off both cable box and TV, disconnecting and reconnecting cables, but no luck. Finally unplugged mains, waited a minute, then turned back on. Everything seems normal now after the reboot. Phew.
