It seams after watching FIOS for awhile the screen starts to have faint black lines running thought it before it goes off with the message NO SINGLE or NOT SUPPORTED on the screen . It goes on and off then off for up to 30 seconds and then comes back on . It might do this couple of times a day but never on other TV just mine. Could it be the FIOS box down stairs cause I had the regular FIOS box on the TV changed or is it something with the TV and Component 1 connection ? It will also display Component 1 on the black screen sometimes.
