Have TV Questions? Ask a TV Technician
Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
Can you access to service menu of TV now?
OK, turn Off the TV to put it in standby mode. Press Mute-1-8-2-Power buttons on TV remote to get into service mode.
Please reply back with the result.
Are you trying it with Samsung TV remote?
This is odd, unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and try again.
Thanks, ***** ***** back with the result.
I'm sorry, I'm out of ideas why TV isn't going into service mode, let me repost this question so other experts can have a look, hopefully some one will soon respond to assist you further.
One more thing came to my mind, put TV into standby mode, press Info-Menu-Mute-Power on TV remote.
Does it help to get service menu?
Just turn Off the TV by pressing power button on remote (do not unplug TV power cord) to get it in standby mode.
OK, so no luck with Mute-1-8-2-Power or Info-Menu-Mute-Power ?
OK, let me repost the question for other experts, I'm opting out now.
Hi. Do the mute, 1, 8, 2 and power button work on their own in normal (inverted) TV operation? Also try different delay (always the same delay between each button in a sequence) as you may push them too slow or too fast.
My pleasure. I assume you are OK figuring the last steps. Be sure to not change any other things than you need as this may render the screen unviewable. Don't forget to rate me :)
