I'm sorry to hear about this problem. Your description sounds like a service issue. Normally, I'd direct to your own country's support, as this is a non-US model, and I support US products and customers. However, you seem to indicate that you're living in a country other than where this model intended for. May I ask which country you reside in now that I can direct you to the right support portal?
I bought Samsung LED TV (Model:UA40EH6030R) on december. Since few days my TV giving me automatic restart issue. It restarts often sometimes in 2-3 mins gap or sometimes stays for long.
Note: No wireless or internet connection attached to the LED and checked sleep timer too which is disabled.
Anyone from samsung please assist or help.
Also, let me know how to register for international warranty for this model.
