It seems new TV.

But that kind of problem is related LCD panel.
If you can replace LCD inverter first.
then not working need to replce LCD panel.

You need to change the 1000uf caps in the power supply. only if you are handy with a soldering iron. Take back of remove psu. You will see them bulging at the top. Think there is 5 to change :)

Your LCD has gone bad or their is a high voltage problem that powers the LCD. Usually a inverter board.

SOURCE: Samsung LCD TV doesn't power on, just blinks 5 times

After about 5 years the Samsung LCD televisions backlight fails which prevents the TV from coming on and the powerlight just flickers the backlight can be changed but it is often alot easier and cheaper to buy a new Television

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

No picture on TV with powerlight on


If you press the power button *on* your TV (rather than using the RC), does the power light still stay on red rather than turn green?

Color problem with Samsung 40 in LCD HDTV


Check your component cables. You have 3 colors coming in. Red,Green and Blue. Make sure the Red cable is good. You can do this by substituting the red cable only, or just change all 3 cables
