May someone please send the service mode specifications for a Samsung LED 40 inch TV UA40EH5000R?
I don't have service mode specifications but I do have a Samsung and looked around for how to get it in service mode some time ago because the HDMI cables somehow disconnected themselves a lot. Thought it was an electronic problem but it turned out to be a parenting problem instead SO I have never used this information and can not vouch for it. I cut and paste it from a note I copied from a forum entry to use at your discretion:
First post:
To enter "Service Mode" Press the remote - control keys in this sequence :
From Standby Info-Menu-Mute-Power On
- The buttons are active in the service mode.
Remote - Control Key : Power, Arrow Up, Arrow Down, Arrow Left, Arrow Right, Menu, Enter, Number Key(0~9)
Careful though there are things you shouldn't touch in this menu.

Good luck. Just a basic suggestion you probably don't need: keep track of any changes made by writing them down so you can put it all back if you have to.
