Hi same here
The cables want to be in their correct place. After you have made sure that the cables and plugs are in their place. Check the input on the remote control. If your connection through the antenna and the the remote does ot show that,move to the antenna input.
The same method goes for the HDMI or ADSL Broadband or what.
Move to the correct input. OH and another matter, check that the scart plugs are iwhere they should be.
Good luck
kolbrun

SOURCE: Samsung LN-R408D - No Picture

My Mom's LNR408D also had sound but no picture. I was able to fix it by soldering in a jumper wire across a blown (1.5A ???) SMD picofuse on the "T-Con" board.
Consider attempting this ONLY if you: 0) Know enough to avoid the potentially fatal High Voltage parts of the power supply board!!!
1) Are a fearless hackazoid 2) know what you're doing with a soldering iron and teensie SMD parts 3) are gonna throw the busted thing out anyway so you have nothing to lose and won't be sad if you screw something up.
4) Know enough to avoid the potentially FATAL High Voltage parts of the power supply board!!!!!

This board is at the top center under a close fitting RF shield. The suspect part was labeled "CP" on the board and marked with "P" on the part. It is visible above the right-center of the connector from the main board. An ohmmeter showed it as open, so I bypassed it with a jumper wire from connector VIN to the hot side of C13. One image shows the suspect part and the jumper in place.

The other shows the TCON board placement top-center (under its RF shield). With care, it seems possible to test the fuse and put the jumper in place without removing the shield. (Obviously don't touch anything else with the VOM leads!)

Thanks to ZORBUS and Steve's TV and Electronics for the idea.

SOURCE: I cannot get my PC sound to play through my Samsung LE32457A HDTV

I hope 3.5mm to twin phono would have plugged in headphone jack of PC to get sound for TV, right?
Reduce PC volume level up to zero and increase it very little bit to get sound in TV.
TV is getting excessive sound level from headphone jack and causing mute circuit to activate to avoid any internal damage.

How to tune in for blu ray dvd

You do not tune in your Bluray player but connect using an HDMI cable or Composite cable. If you have a HDMI cable connect the Bluray's HDMI out to the TV's HDMI in at the back and using the TV's remote switch the Input source to HDMI. You will see the image from the Bluray player in high definition.
If you don not have a HDMI cable connect the composite out of the Bluray player using the Yellow/Red/White cable to the TV's composite input ( same three color sockets ) and switch to AV input on the TV. Using this connection won't give you high definition image but will work OK.

Trying to connect laptop to Samsung HD LCD TV using VGA cable.

I had the same problem with my Samsung series 6 32" Lcd. After many hours of trying different settings and banging my head on the wall I found the solution. What the problem is your VGA cable not supporting the high resilotion of your Samsung TV. The simple solution is to buy a new VGA cable that supports HD. Take a look at this site you need something like this one! Hope this helps.....C
