Fault at its main digital 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. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

SOURCE: No Picture - Samsung LN-S4692D 46in HDTV LCD

My TV (same model) had the same problem except the sound worked (no picture, but the back light works).

Samsung is replacing it with a new model due to a long delay getting a replacement panel.

The TV failed 2 days before the warranty expired.

The new TV has better specs & is now less then half the price of the original.

The repair guy said it's cheaper to replace LCD TVs now then to get them fixed - he said he wouldn't even call a shop unless it's under warranty because you'll just spend hundreds of dollars only to find out a better replacement is cheaper then repairing the old one.

SOURCE: no picture on Samsung LCD 40" TV

Nobody could guess that! it depends on where you are in the world. For Instance I am in australia network.
Call outs generally run to $AUD90 and $90 and hour Min 1 hour.
You do not say whethyer the power light lights up so its again guesswork.
If the power light IS lit then there is power from the wall to the primary coil of the power transformer. I would then suspect either the secondary transformer has failed, or that a fuse after the secondary and pre picture/sound module has blown. The power supply ( cant by bits) costs around $200. The fuse 0.60
add to the callout fees and you get some idea of the cost can cost half the value if a $1000 TV The plasma screen hasnt gone so that's always a plus and its rare for the video board and sound module to fail simultaneously. So my bet is the poer supply side and fuse

SOURCE: TV Cable card slot loses signal immediately after channel find

THis is not a solution but a similiar issue. I have had a scientific Atlantia Cable card with comcast for 3 years no problems at all. Spent the entire day trying to switch to Verizon today. The signal comes across for about 10 seconds, pixelates and then fails. This happen after every start. We have checked the lines, tried 2 cards and reduce the signal. We gave up for today- installed the old Scientic Atlantic, reassigned it to comcast and all works fine Any and ALL suggestions are most welcome Thanks

Samsung flatscreen tv model LN46C600F3FXZX has sound but no picture


Video section has become compromised and no longer functional. Audio being separate from the Video may work perfectly, but the Video portion sustained damage to the circuit board or the inline safety diode blew. If any parts of the Circuit Board fail, you need to replace the mainboard. The cost to generally fix a circuit board is usually more than the replacement cost for a new unit. Check all fuses or circuit limiters inside the TV and if there are no shorts, burned parts, or obvious smells on the mainboard, transient current may have trickled in and damaged sensitive electronics. Have a professional Technician do tests to locate the source of the problem.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Samsung monitor picture clicks off after 2-5 seconds...


Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Samsung flatscreen+ sky+


Is the TV connected using the HDMI port? If so then connect using the component instead and see what happens. If it works ok then possibly a software upgrade on the TV or your sky box.
