Twas the night after Christmas and all was quiet. Mainly because the Samsung 40 inch LCD TV (model LE40R74BD) in my main room had decided to stick on channel 5. It was displaying the picture together with the DTV Channel identification and sound output info-blocks.
Using the remote or on-set controls had no effect, you could not select another digital TV channel, nor could you bring up the digital TV menu, guide, info, or anything else. You could switch to another source including analogue TV without a problem, and once there you could select a different channel in that source (a different analogue station for example).
No amount of switching off or powering off made any difference so it was clear that the software had got a glitch in some register and I would have to reset the box. Of course it was Christmas and a weekend as well, so there was no telelphone support from Samsung until the Monday.
Surfing for a solution to reset the TV, I found a posting in AVForums.com which explains what had to be done but I thought a bit more detail would be welcome.
With the television in standby mode, use the following Samsung remote keys (I have remote model BN59-00516A), one at a time, in the following order:
The TV will power up and after a short delay, it will show the system menu.
We need option 12: RESET.
You CANNOT use the numeric keys to enter the selection. Use the down arrow key on the circular keypad (see picture) to get to option 12, and then press the right arrow key on the circular keypad to make the selection.
The screen will show the word “resetting” in yellow and then both the software and hardware are actually reset back to the initial set up screen.
You will now have to search for both analogue and digital TV services, entering the time and date into the set when prompted. Once this has been completed, you will have normal service resumed.
Why did the issue happen in the first place, after 30 months of flawless service?
Perhaps I changed channels just as there was a complete dip in signal and that confused the TV – I doubt I will ever know but there have been no ill effects in doing a reset. I can give no advice on the other values on the service menu except that there seems little point in just trying them out for the sake of it!
