i have a 22" samsung series 4(450/451) LCD TV, and recently when i turned it on after not using it for awhile, the remote will not work but the light flashing showing that there is a connection. the buttons on the side of the tv do not work other than the power button turning the tv on and off. I am utterly lost and confused as to what is wrong with it. any help/advice would greatly be appreciated. thank you in advance.
