Same Problem with Samsung UE37D5500

I've also encountered the same problem and have also tried the suggested remedies.

One suggestion from other forums is:


Turn off the TV
If you have a 52" Series 6 model (my case), press 'Mute -- 1 -- 8 -- 2 -- Power.' If you have a Series 5 model, try 'INFO MENU MUTE POWER.'
The TV will start and you will be in the service menu (give it a few extra seconds to get there).
Using the arrows/enter buttons, go into 'Option Table (Service)'
Turn off the following parameters: hotplug and hotplugctr.
Turn off the TV.

Unfortunately I am unable to locate hotplug and hotplugctr settings.
Apparently this is a pretty good fix. Any help locating these settings would be appreciated!
