a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Access menu service by press on your command, with your TV OFF:
INFO + MENU + MUTE + POWER ON
Then you should get access to Service Menu.
The last item says: RESET
This will do a reset to the TV.
Make no harm.
WARNING: If when on service menu you feel tempted to "screw" on anything FIRST take note on ALL you change! You can compromise the TV ...

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.

just spoke to Samsung support and it turns out that the freeview tuner had froze and needed resetting. To do this put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu. Press the 'down arrow' untill you've highlighted option 12 - 'reset' and then press the 'right arrow' to enter the option. TV will turn off and when you turn back on it will start in 'plug & play' mode as if new. Set the time and country options and then it will perform a complete scan. I've just retuned mine and all back to normal. Hoorah!!!! :-)
