Question about Samsung Televison & Video
The TV has been 'Locked'. To unlock it press the DISP button for 4 seconds. Since you have a universal remote and there is no way to determine which button is the DISP button try holding each button on the universal remote for 4 seconds until, hopefully, you find the correct one.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Heard back from Toshiba. They said to unplug the TV, wait at least 3 minutes, and then plug it back in. This should allow it to reset itself. Sounded too simple, but after doing just that the tv has worked fine for the last three days! Toshiba noted that if this didn't resolve the problem we should contact them to have a Toshiba Authorized service person come check out the tv. It worked for us, hopefully it'll work for you too. Good Luck

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
