I have a 32 inch Samsung LCD TV. It has worked fine hooked up to a digital cable box for over a year. Suddenly today the screen went black and there is a message box saying ''Weak or No Signal''. All other TV's in the house working fine, so I don't think it is a Cable issue. I tried pressing the Source button on the remote, and I get a message saying ''No Device Attached''. Hopefully this TV isn't toast after a little more than a year!
Try swicth cable box for testing....if sam problem..need replaced tv main board

Thanks.I have tried switching out the cable box, the problem is definitely the TV. Is the main board going out a common problem with LCD TV's? I bought this one 2 years ago because the board went out in a 2 year old Westinghouse LCD. The repair guy at that time said it would cost as much to replace the board as to just buy a new TV. I can't believe this has happened again!
