reseat the LVDS cable inside the unit. this is the cable from the main board to the panel. if the problem is still there then replace the main board 1st, part # BN94-00629F. if the problem is still there then the panel is bad, part # BN07-00245A. if you are not familar with TV repair have a tech repair this for you, if it is under warranty call the manufacturer for nearest repair place.

If this is for a universal remote, the different manufactures assign their own user code to set up their universal remote. They internaly convert to the proper protocol for the TV based on an internal software table.

Can you hear the sound of turning on?
I think that you need to replace the main board.

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.
