SOURCE: Screen goes black

Hai,
Do you see any dull image on the screen ?
If yes the inverter Card/Backlight of the screen is having problem.

Regards,
Aby

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!

SOURCE: SCREEN GOES BLACK AFTER A FEW SECONDS AFTER TURNING MONITOR ON.

More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.

If this helps, please rate my solution. Have a great day.

SOURCE: my screen goes black after a few seconds

Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.

SOURCE: Screen goes black nafter start up. What can I do?

You probably have some bad buffer boards as well as a bad Y-main bd and or a bad X-Main bd. Have a trained samsung tech troubleshoot the set.

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced.

The blue light merely indicates that power is getting to your TV. It has internal power supply problems.
